Open Models vs Frontier Models: Who Actually Wins? | The $100K Token Budget Every Engineer Will Need

Harry StebbingsClay Bavor

YouTube
TL;DR
  • Clay Bavor’s central model call is that cheaper open weights will absorb yesterday’s frontier workloads, but they will not eliminate demand for the frontier itself. GPT-4-level intelligence from spring 2023 now costs roughly one-300th as much per equivalent token, creating an “assembly line” from frontier to fine-tuned open models. Yet coding, science, legal work, invention, and discovery could sustain “unbounded demand for, call it frontier levels of intelligence.”

  • Token prices will fall technologically without necessarily collapsing economically because reasoning consumes more inference while GPUs and power remain scarce. OpenAI’s o1 showed performance continuing to improve with test-time compute, while the founder of Nebius told Harry that even 10X more supply could sell out in a day. Bavor has heard and observed top engineers spending over $100,000 of tokens annually on a run-rate basis and would bet steady-state spend lands “much closer to 20%” of developer salary than 3.8%.

  • AI should produce smaller, higher-leverage teams, but Sierra’s enterprise motion argues against extrapolating a 149-person software company across every category. Its engineers estimate Claude Code, Codex, and Sierra’s internal tools make them three to 20 times more productive, yet customers representing 40% of the Fortune 50 still require integration, trust, regulatory understanding, and forward-deployed help. Bavor’s qualification is important: FDEs are not mandatory, but they are “an important catalyst.”

  • Sierra is becoming AI-native internally through a shared data gateway, a companywide agent, reusable skills, and a strategy model grounded in operating context. Pinecone can interrogate permitted Slack messages, documents, presentations, and reviews; Bavor uses a custom skill to scan every hiring packet. Sierra Brain adds a 20–30-page company primer, board letters, operating reviews, and strategic beliefs to create a “strategy thought partner” that knows the business deeply.

  • The product thesis is already moving beyond customer support toward an agent-mediated front office spanning discovery, sales, conversion, service, and marketing. Rocket deployments cover home discovery, refinance outreach, loan preparation, and servicing, while Next uses Sierra for personalized product recommendations and basket building. The destination is a world where “the conversation is the interface,” supported by reusable vertical expertise rather than an endless collection of bespoke projects.

  • Sierra runs governance and financing around milestones rather than calendar convention or maximal headline valuation. Its board alternates three-hour and 90-minute meetings every six weeks, using six-to-10-page memos because “writing is just thinking on paper”; the cadence let management react when Claude 4.5 and Codex 5.2 changed software development. Every financing round was inbound, and Sierra “guided to and took a lower price” than available to fund the next unequivocally higher watermark.

  • AI fluency is reshaping who creates leverage, how Sierra interviews, and what an entry-level advantage looks like. Some of its most effective employees are 22 or 23 and “completely AI-pilled”; engineering candidates now receive $150 for the coding agent of their choice and build on their own laptops before explaining the result. The broader hiring filter remains “smart, nice, intense,” coupling tool fluency with systems judgment, product thinking, and culture.

Digest · the substance, structured for research

1. Sierra was founded at a platform reset without chasing pretraining

  • Bavor left Google after 18 happy years because late 2022 aligned three conditions: a longstanding desire to found a company, confidence in Bret’s competence and character, and language models reshuffling “the proverbial deck of cards” toward smaller companies. They had known each other for 20 years and had nearly worked together a couple of times before.

  • The key Google inheritance was a willingness to descend as far down the stack as the product required. Sierra anticipated language-model agents in April 2023, recruited the Princeton professor behind the ReAct paper as founding head of research, and built new agent frameworks and architectures when the capability “should be possible” but was not yet operationally possible.

  • Pretraining was considered and quickly rejected. Bavor called a frontier model “a highly perishable bag of floating point numbers” whose initial and continuing capital expense works for very few companies; Sierra instead slipstreams behind labs and hyperscalers, then builds proprietary fine-tunes atop open-weight models. His boundary: control your destiny, but do not invent a story that you must own more of the stack than necessary.

2. Open weights inherit yesterday’s frontier while intelligence demand climbs

  • Harry’s bear-case challenge was direct: if open models can handle an expanding majority of enterprise tasks, does the frontier inherit only increasingly difficult problems? Bavor’s answer starts with the current denominator—fully automated enterprise work remains “a rounding error,” and the gap could reflect model, application-layer, and organizational-diffusion problems alongside model capability.

  • Bavor separates routine capability overhang from high-value intelligence. Any software company would upgrade staff engineers to principal or distinguished engineers; returning shoes does not need the best available model, but coding, legal work, science, materials, invention, and discovery suggest that demand for useful intelligence has no obvious ceiling.

  • The economic pattern is an “assembly line”: GPT-4 in March, April, or May 2023 supported valuable workloads, and equivalent intelligence now costs about one-300th as much per token. Those workloads can migrate to fine-tuned open weights while frontier models remain aimed at tasks where greater intelligence earns its cost, leaving enterprises to mix both.

  • On China’s stronger open ecosystem, Bavor’s hedged explanation was scaled distillation of US frontier training runs. US labs would pressure their own hosted-model pricing by releasing comparable open weights; if another company cannot build the frontier itself, “maybe the next best approach is to distill them and offer them up.”

3. Reasoning and scarce compute keep token economics from collapsing

  • Bavor’s overlooked milestone was OpenAI’s o1 in late 2024. Its test-time-compute chart kept moving “up and to the right”—logarithmically, and therefore eventually flattening—as additional inference and thinking produced better performance. The implication is that cheaper tokens can enable models and agents to consume more tokens in pursuit of greater intelligence.

  • Hardware will produce more equivalent tokens per dollar, and some workloads will migrate to cheaper open weights. But if demand for intelligence is effectively unbounded while Blackwells, H100s, power, and GPU capacity remain limiting inputs, basic supply and demand creates a floor under token costs even when the underlying technology improves.

  • Harry relayed Nebius’s claim that 10X more capacity could still sell out in one day; Bavor believed it. Self-hosting removes part of the frontier provider’s margin stack, but not the constrained physical inputs of energy and compute.

  • Local models can improve consumer experiences but would not by themselves alleviate the server-side challenge. Phones encounter thermal limits; Bavor can imagine language-model-optimized devices or a mains-powered home compute appliance that might help alleviate some demand, but frontier work still requires “a giant rack of TPUs or GPUs in a data center somewhere.”

4. AI-native engineering moves the bottleneck above code

  • Sierra engineers who are deeply using Claude Code, Codex, and Pinecone estimate they ship three to 20 times more features. Bavor expects smaller, higher-leverage teams across functions, but treats the software-engineering and data-analysis gains as already unmistakable rather than speculative.

  • Sierra’s internal foundation is an MCP gateway aggregating its main systems and services into one permission-aware interface. Added to Claude, Codex, or Pinecone, it lets an employee reason across everything they are entitled to see—Slack, documents, presentations, and operating reviews—without granting access to another person’s private material.

  • Pinecone layers company-specific harnesses and a shared skills library onto that gateway. Pinecone knows how to build Pinecone; it has harnesses around its own engineering and around Sierra’s core agent architecture and Agent Studio, where agents are built and deployed. Bavor’s private “Clay scanner” encodes what he looks for in interview packets, accelerating his review and approval of every hire. The system is “approaching indispensable.”

  • Sierra Brain supplies any agent with a 20–30-page account of the company, organization, competition, strengths, and weaknesses, plus recent board letters, operating reviews, and other beliefs about the world. As code generation improves, Bavor expects the constraint to move from writing code, to reviewing it, to deciding what could exist and editing it into what should exist.

5. Enterprise AI still scales through people embedded with customers

  • Harry contrasted Sierra with Lovable, which had reportedly—and, in Harry’s phrasing, “I think”—reached $500 million in ARR with 149 people. Bavor accepted the direction toward leaner teams but rejected a universal template: 50% of Sierra’s customers generate over $1 billion of revenue, 30% exceed $10 billion, and the company works with 40% of the Fortune 50.

  • These regulated, technologically complex organizations are “snowflakes.” Success requires understanding business outcomes, integrating into heterogeneous stacks, building relationships, and earning enough trust to become a partner—not a vendor that “throws some software over the wall.”

  • Sierra borrowed Palantir’s forward-deployed model through early design partners including Olakai, SiriusXM, Sonos, and Weight Watchers. Engineers were embedded so deeply that founding engineer Mihai effectively became a Weight Watchers employee, even receiving performance-review emails. That proximity taught Sierra what deploying customer-facing AI actually demanded.

  • Bavor rejected the categorical claim that enterprise AI cannot sell without FDEs: Sierra’s platform is transparent, exportable, and usable independently. But customer-plus-Sierra deployment has taken Next from kickoff to phone and chat production in six weeks, and Cigna live in roughly 58 days—making FDEs an important catalyst for time to impact and result quality.

6. Sierra is expanding from support into the full customer lifecycle

  • Rocket illustrates the direction: Sierra worked with Redfin to rethink home search, contacted prospective refinance customers, built Rocket Assist to shape loans and gather information, and supported later servicing. Next uses personalized recommendations to assemble outfits and larger baskets. These are inbound and outbound sales motions, not merely support automation.

  • Bavor’s platform strategy is to build applications that inform the reusable platform, making the third, fourth, and fifth applications easier. Coding agents now make a truly unique Fortune 50 requirement economical to build, though his hunch is that apparent one-offs usually recur elsewhere and become shared vertical capability.

  • Competition is the price of a giant market. Bavor says customers are “voting with their feet,” with Sierra multiples larger than its nearest similar-vintage startup competitor and growing faster; because platform breadth and industry experience compound, his hunch is an Uber/Lyft-like market rather than an AWS–Google Cloud–Azure structure, with Sierra seeking the larger pole position.

7. Six-week governance trades ceremonial boards for fast repricing

  • Sierra alternates a three-hour board meeting with a 90-minute one every six weeks because “the AI time clock” outruns quarterly governance. The purpose is to absorb new evidence, update priors, and change course while the evidence still matters.

  • After winter break, Claude 4.5 and Codex 5.2 coincided with what Bavor saw as a fundamental step change in coding-agent capability. It altered Sierra’s software-development method and core product approach—exactly the kind of discontinuity the six-week rhythm is designed to surface.

  • Instead of decks, Bavor and Bret write six-to-10-page memos: “Writing is just thinking on paper,” and writing makes weak reasoning harder to hide. In their first eight quarters, even after beating forecasts, a typical letter names roughly seven areas of dissatisfaction, giving directors time to challenge real questions instead of being presented to and managed.

  • One early admission was that Sierra saw demand but failed to recruit quickly enough in early 2024, leaving additional customers it could have served unserved. Financing follows the same milestone discipline: raise enough to reach the next unequivocally higher watermark, remain sensitive but not maximally so to dilution, and accept a lower price than Sierra could have taken; every round cleared below the available price.

8. Craftsmanship and intensity are operating systems, not slogans

  • Craftsmanship means a great company is the sum of “thousands and thousands” of individually excellent things—people, processes, culture, and product. It also signals how Sierra will treat customers’ most precious asset: during its first Black Friday/Cyber Monday, a lead engineer, operations head, and either founder personally monitored every agent conversation in real time.

  • Intensity reflects competitive reality: customer interaction through sophisticated agents feels inevitable, but no company is entitled to win. Sierra hires against the difficult Venn diagram of “smart, nice, intense,” while Bavor and Bret try to remain the pacesetters asking why something cannot happen tomorrow rather than next week.

  • Founder mode is selective “direct applied force,” not indiscriminate involvement 17 layers deep. Japan exemplifies the method: asking what would make a major business possible this year implied needing 10 people locally, which led to acquiring Opera Technologies and building around Japanese service expectations such as omotenashi.

  • The counterweight is family, one of Sierra’s explicit values. Bavor rejects the “sometimes performative grind” of startup culture: people can turn on the afterburners while protecting children, parents, friends, or whatever matters beyond work. His warning on timelines applies equally—“work is like a gas” and expands into whatever space it receives.

9. AI fluency has become an entry-level unfair advantage

  • Bavor argues young graduates have an unusual opening, not merely a displacement risk. Four years of effectively unlimited time and disposable hours can produce mastery of AI tools that 1,000 companies want; some of Sierra’s most effective employees are 22 or 23, “completely AI-pilled,” and more comfortable with the tools than experienced colleagues.

  • Sierra rebuilt its engineering interview around that reality. Candidates choose an application, receive $150 for their preferred coding agent, bring their own laptop and tools, build, and explain their process. Architecture, systems design, product thinking, values, and “smart, nice, intense” still matter; Bavor wanted every interview to gain a strong AI-native component within two months.

  • In-person work supports the apprenticeship and mentorship that Bavor believes are important for learning. He invokes Richard Hamming’s advice to “find great people, work with them, and learn from them”: knowledge and hard work compound like interest, making early exposure to excellent practitioners potentially trajectory-changing.

  • Cybersecurity looks increasingly important because offensive capability has “ratcheted up five notches.” Bavor nevertheless leaves the product thesis open: the defensive winners might be specialist vendors, or the models and coding agents themselves.

10. Cofounder complementarity converts disagreement into judgment

  • Bavor and Bret recently split over whether a slow area required stronger process or different leadership. They interrogated both views and concluded it needed some of each; their shared test is not ownership of an argument but the truth-seeking phrase, “This is correct.”

  • Instead of dividing the company, they assign majors and minors. Bret majors in sales and software engineering, with instincts on system design and architecture that Bavor trusts deeply; Bavor majors in operations, finance, legal, and running the company. Consequential contracts require both “nuclear keys,” preserving overlap where mistakes would matter most.

  • From Sundar, Bavor learned “dynamic range”—moving from five-year strategy to pixels, drop shadows, sounds, and textures without losing humanity. His broader Google lesson is that an enduring mission, smart people, a truth-seeking culture, and well-directed people caring for many experiments can make an organization feel capable of solving almost anything.

Clay Bavor

We have not yet appreciated the unbounded demand for, call it, frontier levels of intelligence. Part of the driver of the difference is probably the willingness of Chinese companies to do scaled distillation of the frontier models. If you can't build frontier models yourself, okay, maybe the next-best approach is to distill them and offer them up. Every one of our rounds, we actually guided to and took a lower price than we could have. Some of our most effective employees in the entire company are 22 or 23 years old and have been completely AI-pilled. We completely changed our engineering interview process.

Harry Stebbings

When Pat Grady at Sequoia and Neil Maitra at Greenoaks tell you someone is special, well, it kind of means something. Clay Bavor joining me in the hot seat, co-founder of Sierra, one of the fastest growing AI companies in the world. Sierra has raised more than one and a half billion. They work with some of the biggest companies in the world, and they're valued at almost $16 billion, and they work with 40% of the Fortune 50. But before Sierra, Clay spent an incredible 18 years at Google, where he worked on some pretty cool projects. Google Labs, naming one. Google Workspace, Gmail, Google Drive, Google Photos. Jesus, is there anything Clay didn't work on at Google? On top of that, he's just an awesome dude. Luckily, we had a chance to do it in person in London. This was so much fun, and I can't wait to hear your thoughts and feedback on this episode.

Harry Stebbings

Clay, I am so excited for this, dude. I said to you downstairs, we do a lot of shows. I often speak to people before a show. When I speak to Neil Mehta, Ravi Gupta, Sangina, and GV, and I hear what I hear, honestly, they were some of the most astounding references I've had. So thank you for joining me.

Clay Bavor

Oh, it's nice to hear. No, it's a pleasure to be here. Thanks for having me.

Harry Stebbings

Listen, they paid a lot to be featured, so you've got to drop a sponsor.

Clay Bavor

They're great. I'm so grateful to be working with each one of those guys.

Harry Stebbings

It only cost 500 million bucks. I want to start with—I heard that Bret tried to hire you or start a company with you several times before Sierra.

Clay Bavor

Yeah.

Harry Stebbings

Why third time lucky? Why, after 18 years—

Clay Bavor

Oh, third time's a charm?

Harry Stebbings

Yeah. Why, after 18 years at Google, were you like, “Ah, now?”

1. Sierra Begins At Google

Clay Bavor

Yeah. Bret and I met 20 years ago. We both started our careers in the associate product management program at Google. He was class 1; I was class 3. We met in the context of some kind of shared project that we were assigned to, hit it off, and ended up staying in touch socially through mostly a monthly poker group that, in a good year, might play 2 or 3 times, so not quite monthly.

We had always wanted to work together and almost did a couple times. I think when Bret left—I can't remember if it was for FriendFeed or Quip—he tried to get me to join that. The short answer is twofold. One, I just loved my time at Google. Culturally, it was me. I learned more than I could ever imagine having learned in those years.

The people were so extraordinary to work with. I had a series of managers and leaders I got to work with who took bets on me and gave me, on paper at least, more responsibility than I deserved. I also got to work on truly fascinating things. I was just incredibly happy and engaged and growing as a person and professional.

And then, in late '22, the planets aligned in a way that I didn't think they would probably align again. I'd always wanted to start a company. I started a very modest company when I was 13 years old and always thought I would start another. If you're going to start a company with someone, you want to make sure that they're excellent in competence and in character, and then that the timing is right.

We could see that language models were going to be a thing. If ever there was a time when the proverbial deck of cards was shuffled in favor of smaller companies, it was at the advent of a new technology. So, happy at Google, the planets finally aligned, and I took the leap. We're 3 years and change in now.

Harry Stebbings

18 years at Google—

Clay Bavor

Yeah. Well, I started counting in colleges. Gosh, I've been there 1 college, 2 colleges, 3 colleges, 4 colleges. Yeah, it's a long run.

Harry Stebbings

That's even more terrifying.

Clay Bavor

Yeah. It's a long run.

Harry Stebbings

My question to you on the back of that is—and it's a terrible question, so you can chastise me for it—what are your single biggest takeaways from that experience that you took with you to Sierra?

Clay Bavor

Mm-hmm.

Harry Stebbings

And what did you leave behind?

Clay Bavor

It's such an interesting question. Of course, the scale of a 2-, then 10-, then 100-person enterprise software company is very different from—I think when I left Google, it was roughly 150,000 people. Things that I've definitely brought with me, number 1, are a willingness to invest as far down the technology stack as you need in order to build the service and product that you want.

Google, I think, from the early days, famously built its own, if not data centers, cluster architectures, and was really the first to use commodity hardware. That required building novel distributed systems for serving and data storage and so on.

And so we could see as early as April of '23, when we started the company, that agents were going to be a thing. This was before all anyone wanted to talk about was agents. We realized, okay, this should be possible. It's not yet possible, but we're going to have to invent frameworks for building these things, our own architectures really from scratch.

So, actually, our founding head of research was the Princeton professor who literally wrote the paper on language model-based agents, the ReAct paper. So we invented and went further down the stack than I think some companies at that point would have been willing to. We're not doing our own pre-training. We'll leave the capital expense there to the labs and the larger companies.

Harry Stebbings

Before we move to 2, can I ask: did you consider training your own models? Because I completely understand the desire to own as much as possible.

Clay Bavor

Yeah.

Harry Stebbings

Did you consider training your own models? And what was the thought process around not doing so?

Clay Bavor

It's a great question.

2. Why Sierra Skipped Training

We did briefly and discarded it. If you recall, in late 2022 and early 2023, as a startup in AI, you were kind of nobody if you weren't doing your own pre-training and building your own foundation models. Character, Inflection, and Adept had great people at these companies, but the capital expense—the ongoing capital expense—to create what is effectively a highly perishable bag of floating-point numbers just doesn't work for any but a small number of companies.

And so our calculus was, for areas that are deeply capital-intensive, how do we slipstream behind the investments that the labs and the hyperscalers are making, take as much as we can off the shelf, while still being willing to engineer more deeply? So today we have a set of our own proprietary fine-tuned models, but these are fine-tunes on top of open-weights models. We're not going all the way down to the mega-cluster training runs.

I think it's important that you are in control of your own destiny enough, and that you don't tell yourself a story that you need to go further than you actually need to go.

Harry Stebbings

Is the future open models fine-tuned to specific company needs? And if that is the future, with the realization that frontier models are too expensive, is that a bear case for frontier models?

Clay Bavor

I think it's a lot more complicated than that. If you asked any software company, "Would you like to upgrade your staff-level software engineers to principal- or distinguished-level software engineers, yes or no?" 100 out of 100 would say, "Yeah, that sounds pretty great." So I think we have not yet appreciated the unbounded demand for, call it, frontier levels of intelligence.

Now, you don't need that in every domain. For instance, in our own business, we build AIs for companies to interact with their customers. You don't need Mythos to return a pair of shoes, right? You're good. You want to do that well, but we've got some capability overhang, so to speak, for doing something like that.

But in a range of domains—coding, certainly; science; materials science; legal—where the stakes are very high and there's a high degree of complexity, I think we're going to see effectively unbounded demand for greater levels of intelligence, and therefore for frontier models. That said, there will be an assembly line of, "Cool, GPT-4, which in March, April, and May of 2023 was good enough to do some set of things, is now 1/300th the cost for an intelligence-equivalent token." And so you'll have some assembly line of taking models that were once at the frontier to perform certain workloads, and then building open-weights fine-tuned models for those.

I think you'll end up with companies using both, mixing and matching them depending on the task at hand.

Harry Stebbings

As we see open models become more and more advanced, does that not mean the problem set for frontier models becomes more and more challenging? As you said, we've seen the progression of open models so much that they can actually do the majority. I get it for solving climate change, cancer treatments, and materials science, but for the majority, what percentage of enterprise tasks can be done with open models today?

Clay Bavor

Well, I think if you look at what percentage of enterprise tasks are completely automated today, it's a rounding error, right? It's very low. So is that a model gap? Is that a gap in diffusing the technology into the company? Is that an application-layer gap? I think it's probably all of these.

You're obviously correct that as the open-weights models become more capable, the set of things they can do grows larger. The set of things where, all else being equal, if they're much less expensive, you would want to point a frontier model becomes smaller. But again, I think we're not imagining just how high the ceiling is in terms of demand for frontier intelligence.

Invention, discovery, building new products, and building new services—I think it's hard to get your mind around, when you have intelligence that can work around the clock to invent, build, and discover, how you would use that and how much of it you could use.

Harry Stebbings

Can you help me understand? When we look at token economics, we thought that with chat, tokens over time would go down in cost. And with the movement from pure chat to chat and agents, and an agent-economy-based model, we're seeing token costs increase, not decrease. How do we see the evolution of token costs with the evolving formats, do you think?

Clay Bavor

You missed one thing in there, which is that a large amount of token use is driven by reasoning models now—thinking out loud to themselves. I think one of the most underrated developments of the past few years was the o1 model from OpenAI in late 2024. If you recall, there was a chart that showed test-time compute, or the amount of inference done—the amount of thinking out loud—and performance, and it just keeps going up and to the right.

It's logarithmic, so it starts to level out. But what it effectively demonstrated is that if you have enough time and compute, the model will be that much smarter.

As for what happens with token economics, I think there are many drivers underneath it. One is that you're going to end up with hardware that is able to produce more tokens at equivalent cost. The cost of the inputs, so to speak, will go down. We talked about how you'll have this migration of certain workloads to open-weights models.

I think one of the drivers that's hard to predict—how it will play out across both the open-weights models and the frontier models—is just the availability of compute. It's classic economics, microeconomics 101: supply and demand. If you have unbounded demand for frontier-level intelligence or GPUs to run open-weights models, and the rate limiter is the number of Blackwells and H100s you have, you end up with a floor on the cost of tokens because you've got to pay for the energy and you've got to pay for the compute.

Harry Stebbings

We had the founder of Nebius on the show the other day, and he said that if they 10x supply, they could still sell out in a day.

Clay Bavor

I believe that. And I think that makes the point, which is, okay, open-weights models will be cheaper because you're avoiding some of the margin stack in the hosted frontier models. But what is the fundamental input? It's GPU capacity and power. That's still constrained.

Harry Stebbings

One thing that could slightly alleviate that is actually running models locally. People say that it could be—

Clay Bavor

Yeah, on your cluster of Mac Minis or whatever?

Harry Stebbings

Yeah, or even on-device, on phones. I don't quite understand that when we think about always-on AI, 24 hours a day. That's an awful lot to run locally. Is it a pipe dream, or do we think that's actually a reality that would alleviate the server-side challenge?

Clay Bavor

Oh, it certainly wouldn't alleviate it. I think it will make some consumer applications much better. But the reality is you need petaflops and exaflops of compute, certainly for training, and you want a whole bunch of compute quickly at inference time. You just run into thermal limits on your phone.

I do think it's shocking that we're all carrying around hypercomputers in our pockets these days. Will they get better? Yes. Will you have language-model-optimized hardware rolling out in our phones and in our computers? Yes. I can see a sort of home appliance where you plug into the mains and get on-demand access to a whole bunch of compute for things in your home, and maybe that helps alleviate some of it.

Certainly for frontier workloads, though, there's one place you can go for that, and it is a giant rack of TPUs or GPUs in a data center somewhere.

Harry Stebbings

We spoke about frontier versus open. Now, frontier models, obviously, you have OpenAI and Anthropic in the US, who are the dominant leaders—everyone knows.

Clay Bavor

And my alma mater, Google.

Harry Stebbings

And Google, of course. We had Demis on the show. Incredible, incredible. I love Demis.

Clay Bavor

I loved Demis, too.

Harry Stebbings

Also one of the most humble leaders I've ever met, so I absolutely agree there. Open models in the US have lagged behind. We see Chinese models being unbelievably advanced and impressive. Do you agree that we have a challenging open ecosystem in the US, and does that worry you?

3. The Chinese Distillation Advantage

Clay Bavor

Part of the driver of the difference is probably the willingness of Chinese companies to do scaled distillation of the frontier models from the labs. My impression is that many of the open-weights models coming from China are derived from training runs done in the US.

I think if you have the US-based labs and hyperscalers developing the frontier models, there's an obvious question: Are they going to compete with themselves and drive price pressure on the frontier models by developing and releasing open-weights models that are of similar capability? If I was running that business, that's not something I would do.

So if you can't build frontier models yourself, maybe the next-best approach is to distill them and offer them up. I think that's probably the main driver of the difference.

Harry Stebbings

I have to ask: You mentioned earlier that enterprise is a team sport. I love that.

Clay Bavor

Mm.

Harry Stebbings

And you mentioned earlier who wouldn't want more advanced software engineers internally. Lovable announced yesterday that it had hit, I think, $500 million in ARR with 149 people. And in a show that comes out tomorrow, Rory, who's one of my co-hosts on this weekly show that we do, says, "Well, if you're Sierra, you can't do that." I mean, as you mentioned, Sierra is an enterprise business, and you have to have a different structure for the team.

When you look at the future of teams, are we seeing a world of dramatically leaner, fewer people in teams, or is it still very much dependent on customers? Will we still have very large teams for companies like Sierra with enterprise customers?

4. The AI Native Company

Clay Bavor

I think the general direction of travel clearly is toward smaller, higher-leverage teams. We have software engineers who are completely AI-pilled and using Claude Code, Codex, and our own internal agent, which we call Pinecone and use to run much of the company. They estimate they are between 3 and 20 times more productive in terms of features shipped.

The productivity gains, certainly in software engineering, data science, data analysis, and other areas, are coming in spades. I think, in time, it will touch all parts of really every company. So that's the general trend.

I think within a company like Sierra, where we serve, in particular, the large enterprise, we work with 40% of the Fortune 50. We have 50% of our customers doing over $1 billion in revenue, and 30% doing over $10 billion in revenue. These are some of the most complex and, in some cases, regulated organizations in the world.

To be able to sell and implement our product and solution successfully for organizations that are snowflakes, the process of selling and, more importantly, successfully implementing and deploying a solution like ours into the large enterprise is still a lot about deeply understanding our customers' business outcomes and objectives. It's about understanding their technology stack, integrating with it successfully, building relationships, and earning trust to show up not just as a vendor that throws some software over the wall, but as a true partner in diffusing this technology into, in our case, all of the front office—sales, support, marketing, and so on.

Harry Stebbings

I mean, there's so much for me to unpack there. I was scribbling furiously. You mentioned the internal agent, Pinecone.

Clay Bavor

Yeah.

Harry Stebbings

Can you talk to me about what that is, how it was built, and what it does? I'm intrigued to see how companies change and how they operate.

Clay Bavor

Yeah. It's one of the more significant developments in how we run the company over the last 6 or 9 months. We began by building what we call our MCP gateway. This is a single MCP server that aggregates all of the main systems and services that we use to run the company.

You can add this single gateway to your Claude instance, your Codex instance, and indeed to Pinecone. Basically, via any one of those agents, you have full access, with the permissions, of course, that you have as an individual at the company. You can't read someone else's documents, but you can read your own Slack messages.

It's like having superpowers, right? You can interrogate, in essence, the entirety of the company—all information that is published, whether it's Slack messages, presentations, operating reviews, and so on—and use that access to better reason, make decisions, and get things done.

Pinecone, of course, incorporates that MCP gateway, but then is a purpose-built harness for all of Sierra. Pinecone knows how to build Pinecone. There's a whole harness around the engineering of Pinecone, and our engineers there are phenomenally productive.

We have a whole harness around the core of our platform—our agent architecture, Agent Studio, where you build and deploy agents—which speeds up software development there. Then we have a shared library of skills that anyone at the company can build. You can build one that's private to you.

I have a whole bunch of skills, including one that is basically the Clay scanner for interview packets. To date, I review and approve every single hire we make, and I get some help from Pinecone. I've basically taught it what I look for and what I scan for: flag these if there are any instances of them. It's a shortcut to a faster, deeper read of every packet.

Pinecone has just become this approaching-indispensable tool for running the company. I think we're not quite there yet, but we're approaching indispensable. I could go on about some of the other interesting things we've built. I've been working on what I call Sierra Brain and some other things in the same vein.

Harry Stebbings

What's Sierra Brain?

Clay Bavor

Sierra Brain starts with a 20- or 30-page document that grounds any agent in what we are as a company, what we do, how we're organized, our team structure, the competitive landscape, our strengths and weaknesses, and all of these things.

On top of that, I've given it access to every one of our recent board letters, every one of our recent operating reviews, and other insights and observations we have about what we believe to be true about the world. I can then use it to reason about what we should be doing as a company.

So it's a bit like a strategy thought partner, if you will, that knows the company, if not inside and out, very deeply.

Harry Stebbings

We're going to get to your board letters, because I heard about these.

Clay Bavor

Oh.

Harry Stebbings

And how you have boards every 6 weeks, not every quarter—

Clay Bavor

Yeah.

Harry Stebbings

—because the world moves too fast, apparently. Trust me, I stalk the shit out of you. But I just wanted to stay on internal builds. You mentioned the internal agent that you have. We're having a lot of CEOs who I speak to say, “I have no idea. Do I just let my dev teams run wild on token spend? Do I give them some form of budget?” Or—

Clay Bavor

Token maxing.

Harry Stebbings

Yeah. What's your personal take, and what do you and Bret say around the fire? Do we put a cap on this? Do we just encourage them to go wild? How do you approach it?

Clay Bavor

Yeah. I think over the past 6 months, using a bunch of tokens was a proxy for using AI. You were leaning into it and trying to be more productive with it, so I think it's generally been a positive signal.

I have heard and observed that top engineers who are really leaning into Claude Code, Codex, and so on are spending more than $100,000 on a run-rate basis on tokens per year. That's a meaningful fraction of an engineering salary.

I think the direction we're headed is toward some amount of token budgeting on a per-employee basis. For CFOs in the future, capital allocation will look more like how we allocate OpEx and then headcount. Headcount will be both headcount for salaries and SBC, and also tokens associated with headcount.

So

here's your salary, here's your token budget, have at it. We are not yet at that point. Our usage, compared to some of those larger numbers, is modest, and I think the benefit of learning at the fastest rate possible outweighs the capital discipline at this point. We prefer to learn quickly and see what works.

It'll be interesting to see how the rate limiter in software development moves around—what the Andy Grove “breakfast factory” constraint will be, what the constraining factor is. It used to be writing code. Now it's probably reviewing code. Pretty soon it will be deciding what is worth building and editing what could exist into what should exist. The dynamics there will be interesting.

Harry Stebbings

I think the core question for us to understand if everything is slightly overhyped is: what percentage of developer salary will be spent on tokens in the future? Mark Benioff said that he spends $300 million a year on Anthropic for his dev teams. That works out to about 3.8% of developer salaries—not actually as much as the headline $300 million makes you feel.

If it stays at 3.8%, a lot of the companies that we're investing in and seeing around us are actually grossly overvalued. If it goes to 20%, they're undervalued. I had Brandon at Macaw on the show, who says he spends more on tokens than he does on headcount.

Clay Bavor

Yeah. I think 3.8% is wildly off from where the steady state will converge.

Harry Stebbings

Where do you think it will be? I'm not going to hold you to it in 5 years' time, but do you see it being at 20%?

Clay Bavor

Oh, I do.

Harry Stebbings

So the $100,000 a year actually will be normalized? If you think about a great dev in the Valley, I presume $500,000 is where they're at?

Clay Bavor

Sure, that would be the upper end.

Harry Stebbings

So it feels normal.

Clay Bavor

Yeah. I would not bet on 3.8%. I would bet on much closer to 20%.

In software engineering, the gains to me seem unequivocally there. You can debate whether it's 2X, 10X, or 20X. Even if it's 2X, you've just effectively doubled the size of your engineering team. That's remarkable.

Harry Stebbings

You mentioned 40% of the Fortune 50—

Clay Bavor

Mm.

Harry Stebbings

—being customers.

Clay Bavor

Mm-hmm.

Harry Stebbings

You use that quite a lot in your marketing materials, and it strikes me as a very enterprise company. Is it difficult—or how do you retain a real product focus and a real closeness to customers when you're so enterprise? Is that difficult?

5. Staying Close To Customers

Clay Bavor

I think it's a little bit of a false choice you're implying there. I think being a large enterprise doesn't necessarily mean you need to be distant from your customers—in our case, our customers' customers.

Bret and I are constantly building agents ourselves. One of the more interesting things of the last 6 months is that we released Ghostwriter. This is an agent for building agents. It's agents all the way down. It's pretty cool.

We are constantly in the products ourselves. Bret is actually still an extraordinarily capable software engineer. It's remarkable. Some of the code that's in production, he has written.

I’ve probably got a couple of lines here or there, but it pales in comparison. Of course, we can’t on our own simulate the complex, multisystem environments that characterize many of our largest enterprise customers, so we have to simulate them in our heads. But we’re in the product.

One of the things I think a lot about is that we will, in short order, be one of the larger B2C companies. We’re doing that via our customers. We’re serving hundreds of millions of interactions—soon, billions of interactions. So staying close to the end experience as well—the voice fluency, latency, quality of the experience, all of that stuff—is very energizing and something that we’re close to. I don’t feel distant from the product, either from our customers’ perspective or from their customers’ perspective.

Harry Stebbings

I always looked at the space itself, and I was like, “Amazing space. What a huge TAM. What a problem, and AI is perfectly suited for it.” Then I peek under the covers, and I’m like, “Oh my God.” There are 15 companies funded with $100 million, Salesforce, Atlassian, Zendesk, and all the other incumbents. What is the market maturation of this space? Help me understand how this evolves over a 5- to 10-year period.

Clay Bavor

I think, first of all, to state the obvious, the great thing about being in a giant market is it’s a giant market. The challenging thing about being in a giant market is it’s a giant market, and other folks know it too. It’s startups, long-standing companies, and the incumbents.

Your point about it being competitive is certainly right. Five or 10 years, especially in the age that we’re in, is a long time. What I would point to is that, amongst the startups, customers are voting with their feet. We are multiples the size of our next-nearest similar-vintage startup competitor, are growing faster, as I said, and are working with many of the great companies in the world.

Harry Stebbings

Do you think it’s like an Uber–Lyft market, or do you think it’s an AWS, Google Cloud, Azure market?

Clay Bavor

It’s hard to know. I think because the economies of scale in terms of depth and breadth of platform, experience in specific industry verticals, and so on really compound, my hunch is that it will be more like an Uber–Lyft market. We obviously think we’re in the pole position to be the bigger of those two.

Harry Stebbings

Again, you sell to some of the biggest enterprises in the world. I had a guest on the show the other day say you can’t sell to enterprise without an FDE motion.

Clay Bavor

Hmm.

Harry Stebbings

Would you agree with that, knowing all that you know now, selling to 40 of the 50?

6. Forward Deployment Wins

Clay Bavor

I would like to think that, at least in the AI space, I rediscovered and borrowed this model from Palantir, and we came to it almost accidentally. We started the company, and the first thing we did was reach out to people we trusted to understand what the biggest unsolved problems were that they were looking at. We saw, “Oh, interesting—service and support as a foothold into something much broader: helping support customers across the entire lifecycle.”

We then enlisted half a dozen design partners that we built the first version of our product and platform with and for. These are, in the history of the company, legendary companies: Olakai, SiriusXM, Sonos, and Weight Watchers. We built the first version of our platform with our engineers deeply embedded inside those companies—so much so that our founding engineer, Mihai, was actually an employee of Weight Watchers, including getting performance-review-time emails and so on.

What we realized was that no one had ever deployed an AI agent. No one had ever put AI in this way in front of their customers. In order for us to build the best thing as quickly as we and our customers would like, being so close to the business—the mechanics of it, the people, their business model—so that we understood it, I won’t say as well as our customers, but approached that level, we saw so much power in it.

Starting in early 2024, we really started building out this forward-deployed team. Customers use it in widely ranging ways. Our platform is highly extensible and very transparent. You can see exactly how an agent is built. You can export agent definitions and completely build your own, so there’s no need for forward deployment if you don’t want it.

What we generally find, though, is that in getting started, having Sierra and help from our teams drive while our customer is in the passenger seat—but navigating for the first version—is what has enabled us to take companies like Next live in 6 weeks, from kickoff to live behind their phone number and chat. Or Cigna, one of the largest healthcare companies in the world, live in, I think, 58 days.

Time to market, time to impact, time to value, and then the quality of the result—we think it makes a big difference. I wouldn’t say it’s binary, though, as you framed it. I do think you can sell without a forward-deployed team. But for getting to the impact of this technology as quickly as possible and at the magnitude that we know is possible, it’s an important catalyst.

Harry Stebbings

Are we at a unique time in history where, for this specific moment in time, every buyer is in the market for the product? Normally, not everyone is in the market for a product at the same time. Every CEO is being told by their board, “How are we using AI?”

Clay Bavor

Yeah.

Harry Stebbings

Is it a unique time because there is a buyer pool like never before for this specific moment?

Clay Bavor

There is effectively unbounded demand, I think, in 2 areas. One, we’ve talked about coding agents. The other is the space where we’re the category leader. One of the reasons we’ve grown as quickly as we have is to meet that moment and meet that demand.

We’re now 100 people here in Europe. We recently acquired a company in Japan, Opera Technologies. You and I were talking about this. To hit the ground running there and to have a team that can be attuned to the cultural nuances of Japan and the concept of omotenashi, which is extreme hospitality—that is what is expected in Japanese service, and that’s what we intend to build there.

Harry Stebbings

Starting with the beachhead in customer support and customer service, to scale into the company you want to be, you have to move out of customer support into complete lifecycle management, I guess. Is Sierra a sales platform in the future? Is it a conversion platform? Is it a marketing platform? What is it?

Clay Bavor

I think Rocket is actually a pretty good indicator of the direction that we’re headed. You think about the life of a Rocket customer: it begins with search and discovery of a home they might want to buy. We worked with Redfin to rethink their search experience. We help Rocket reach out to folks who’ve expressed interest in a refinance and make contact that way. We worked with them to build Rocket Assist, to help bring people in and help them shape and size their loan, gather all the information needed, and so on.

None of that is service and support. We do do that—loan servicing and so on. So I think that’s a good example of where things are headed.

Harry Stebbings

That’s an inbound sales machine.

Clay Bavor

Inbound and outbound, you’re right. It’s not just Rocket alone. With Next, we worked with them on personalized product recommendations. How do you help someone build an outfit and a bigger basket of things they will love? Again, that’s much more sales than support.

Harry Stebbings

This sounds and feels more like a Fortune 50, Fortune 500 Palantir, but more consumerized, where you’re building these amazing solutions for these products to fit their needs. Is that unfair of me?

Clay Bavor

First of all, Palantir is an amazing company. We have taken a lot of inspiration from them and copied elements of their forward-deployed approach. My understanding is that Palantir has a low hundreds of customers. We are, and intend to be, at a much larger scale than that, and I think where that will come from in particular is building real domain expertise in specific industry verticals.

Of course, our first, second, and third customer deployments were, by definition, unique and one of a kind. I think we’ve learned some things about how to help build a basket in the retail setting and, in some of these other industries, how best to handle a question about the status of a healthcare claim, a healthcare insurance claim, or questions about a fee around a checking account.

I think we’re going to have these deeper and deeper lessons in specific industries and be able to apply those in a much more scaled way.

Harry Stebbings

Will you build products that aren’t uniformly applicable across customer bases? If one customer needs specific cart-abandonment product features, is that something you build? Or is it, “No, that’s not applicable to the platform”?

Clay Bavor

One of our approaches in building the company—and this goes back to where we started—is that you can build a platform and hope that people come, with the applications getting developed on it, or you can build applications to inform a platform that makes building the third, fourth, and fifth that much easier.

Wherever we can, we’re scanning for opportunities to strengthen our platform. Commonality is much better than something that is truly one-off. That said, if we’re working with a Fortune 50, Fortune 20, Fortune 10, or Fortune 5 company and there is some element of that company that is literally unique, of course we’ll build that.

One of the neat things is that it’s actually become feasible to build that because of coding agents and the pace at which you can move.

There’s a real unlock in being able to build a solution on an already deep platform, but extend it in ways that may apply to a single customer. My hunch, though, is that if you build it for one, someone else is going to have that same problem, right? And so it’s less common than you would think—true one-of-ones.

Harry Stebbings

I do want to go to the way that you run the company. It was so important in so many of my conversations before this. If we start with the board meetings, I spoke to, as I said, many of the investors. Every 6 weeks, not every quarter. Can you talk to me about your biggest lessons on how to really get the most out of your board and run the best board meetings?

7. Running Sierra With Intensity

Clay Bavor

We do a couple of things. You mentioned the 6-week cadence. We have kind of a tick-tock: a 3-hour meeting and a 1.5-hour meeting. We’ve done this since the beginning of the company because we could just see that if you’re on the AI time clock, it moves a lot faster. Things are changing.

Most recently, we came back from winter break and suddenly coding agents were amazing. You had Claude 4.5 and Codex 5.2. There was a fundamental step change in the capabilities of these models. It changed our approach to software development. It changed our approach to the core product. And so having a cadence where you can take in information, even from the last 6 weeks, update your priors, and then change course, I think, is quite important.

As for running the board meetings themselves, we don’t have board decks; we have board memos. Bret and I write a usually 6- to 10-page memo. There’s a saying, “Writing is just thinking on paper,” and I think it’s very hard to hide from writing. Getting our thoughts clearly out onto paper, sending that in advance, giving each of our board members some kind of soak time to think through the issues and come prepared rather than be presented to and managed, I think, is a big part of it.

The contents of the board letters themselves, I think, are notable. We’ve done quite well in our first 8 quarters in market, and generally, the format of a board letter is like, “We exceeded forecast by a wide margin yet again. Things are going well. We landed these customers, and here are the 7 things we think we could be doing better, where we’re unhappy, where we could be going faster, where we need to hire in this area, and so on.” The board meetings then kind of take form on their own based on that.

You get the scaffolding right. You get the people right. You set the table with the big questions we’re asking, and then genuinely invite our board members in to challenge us and improve and sharpen our thinking. Those are some of the ingredients.

Harry Stebbings

I heard that you also write about everything that you suck at.

Clay Bavor

Yeah.

Harry Stebbings

What was one of the most memorable writings on what you suck at?

Clay Bavor

One early on was that we had such good indicators of the demand we were going to see, and we just didn’t hire fast enough to meet that demand. It was like, “We could have taken on this additional set of customers.” We had the data in front of us. We could see it, and we didn’t act decisively enough to build out a recruiting team and scale faster.

This was early 2024, so early days in the company. We’ve since corrected, but that was one that stands out.

Harry Stebbings

We are going to go to hiring. You mentioned some of the people around the table.

Clay Bavor

Mm.

Harry Stebbings

You and Bret—I mean, it’s the dream team of the best of the best operators. You can choose any investors at almost any price, which is kind of hard. How do you and Bret sit down and discuss price on a new round? Because investors will pay anything to get in.

Clay Bavor

Mm.

Harry Stebbings

You want it to be high, obviously—

Clay Bavor

Yeah.

Harry Stebbings

—but also not too high. How do you actually think about that? Is it like—

Clay Bavor

Yeah.

Harry Stebbings

—okay, three is on next year's target? What does it look like?

Clay Bavor

It’s generally been inbound, is the answer. We think about it, honestly, not in terms of valuation. We think, what is the amount of capital that we need to raise to get to the next unequivocally higher watermark in terms of revenue, company scale, and so on?

We think of it as milestone-to-milestone funding. Then we’re sensitive, but not maximally so, to dilution. How do you balance those things? Every one of our rounds, we actually guided to and took a lower price than we could have.

Harry Stebbings

I again spoke to them, and they said the values within the company are craftsmanship, intensity, and family.

Clay Bavor

Mm.

Harry Stebbings

Craftsmanship, intensity, and family are 3 that I wouldn’t normally see.

Clay Bavor

Mm.

Harry Stebbings

Can you talk to me a little bit about why those are so important?

Clay Bavor

Mm. I’ll start with craftsmanship. Both Bret and I, just because of the way we are, care about doing things well. If you’re going to do something, do it with excellence. There are 2 ways in which doing things with excellence means much more than just sweating the details.

One is, what is a great company? A great company is an aggregation of thousands and thousands of things that are themselves great. It’s great people. It’s processes that are well-designed. It’s a great product. It’s a great culture. So how do you build an excellent company? You build everything with excellence.

I think holding ourselves to the standard—if it is worth doing, it is worth doing well—is one part of that, because that adds up to a great company.

How else do you get there? The other is, you think about what our customers are trusting us with. Back to the trust value, but I’ll make the connection with craftsmanship. It is their most precious asset. It is their customers. How will a company know—how will a set of people who are considering working with us know—how we will show up with their customers? A lot of it is how we show up with them.

Sweating the details in how we show up and interact with our customers, the level of professionalism and care, dropping everything when something matters. I’ll give you an example there. In our first Black Friday/Cyber Monday with a set of retailers, one of our lead engineers, our head of operations, and either Bret or me were in real time personally reading every single conversation that our agents were having.

We wanted to make sure we were doing right by our customers. So that’s craftsmanship, and again, it adds up to a great company. It’s very meaningful in helping our customers understand the care we will have for their customers.

Harry Stebbings

Intensity and family.

Clay Bavor

Yeah.

Harry Stebbings

Can you expand on those? Again, 2 that I don’t often get.

Clay Bavor

It’s back to this great thing about giant market—giant market; hard thing about giant market—giant market, and others are in it, too. I think there is an inevitability to companies interacting with their customers via really sophisticated agents that capture all that they know and all they can do on behalf of their customers, get the job done on their behalf, and handle the complexity, as opposed to pointing you to websites. The conversation is the interface, right? I think there’s an inevitability to that.

Therefore, in order to win, in order to build the best company in the space, it is about pace. It is about winning. It is about building the best product. It is about being competitive and being intense about it. We don’t have the luxury of patience. There’s nothing written in the wind, right, that any particular company will be the company.

Showing up in our 5th engagement and 500th engagement as intensely as we did our 1st—you have to do that. I talk about the Venn diagram of who we hire for: smart, nice, intense. It’s hard, actually, to get all of those 3 in a single person. When you do, it’s fantastic. You can feel it in the office. Another way of translating intensity is doing things with excellence and doing things with pace. It relates to craftsmanship as well.

Harry Stebbings

Is there anything that you can do or add to an organization to increase or maintain intensity, be it timelines, rewards, or incentives? How do you keep intensity with scale?

Clay Bavor

I think it starts with the founders. Bret and I are quite intense. We have to be the pacesetters, right? We have to be the examples of intensity. It shows up in how we manage the company. He and I are deep in the details and are constantly asking, “Is this good enough? How could this be better? How could we go faster on this? Why can’t it happen tomorrow instead of next week?”

I think it has to start with the founders, as one.

Harry Stebbings

How do you determine what you should be in versus what you shouldn’t? We’ve seen the resurgence of founder mode, of founders being in the weeds.

Clay Bavor

Yeah.

Harry Stebbings

It’s also not possible in everything, and it’s not right in everything. How do you determine that?

Clay Bavor

You have to edit it. You have to have judgment for it. I think you have to look at what is the thing that is not going to happen, or won’t happen as quickly, without direct applied force from one of us or both of us.

It’s pointless to be in, quote, “founder mode,” 17 layers into the details of something that doesn’t matter. It matters a lot if it’s our next-generation agent architecture and there’s something that we can add. We try to be selective about where we engage at that level, but it’s anything but hands-off management.

So I think it starts with this: a founder's ambitious goals have a way of becoming self-fulfilling. You set out a goal, whether it's the quality of a product or a revenue number, and ask, “What would have to be true in order to get there?” Let's suspend disbelief and just imagine: What would have to be true to cover this much ground this quickly? Why can't we do that? Okay, why shouldn't we?

Japan is an interesting example of that. Why can't we have a giant business in Japan this year and not next year? What would have to be true? We'd have to have 10 people on the ground. I was like, “Why don't we buy a company there?” You see how this stuff hangs together. Ambitious goals can take the form of a date, sure. Date-driven development can sometimes work. I think work is like a gas and tends to expand to fill all available space that you give it. And so there's a danger in setting dates as well, where it's like, “Well, we've got this long.” It may not need to take that long.

Harry Stebbings

It ties to the third one: work expands to the room that you give it. I give everything to my work, and I love that. Third, family as a value.

Clay Bavor

Yeah.

Harry Stebbings

I'm just interested by that one.

Clay Bavor

Yeah. Each of our values comes directly from Bret and me, and one of the best decisions we made was—I think it was when we were 5 or 6 employees—we spent half a day. Bret and I have a technique we call “think apart, think together,” where we'll initialize on a prompt, and the idea is not to groupthink one another. We want to get the best of our independent thinking.

So we did a think-apart, think-together on values, went off and spent an hour writing up what our view was, came back and compared notes, and there was, first of all, a shocking amount of overlap, which I guess shouldn't have been surprising in retrospect. We'd wanted to work together. We'd been friends. I think we were deeply similar in many of our values—really all of our core values, I would say.

Family comes from the fact that I've got 4 young kids, Bret's got 3 kids, and I married my high school sweetheart. I think for both of us, the only thing that's more important than Sierra is our families. Our belief is that you can be part of something that's growing fast. You can be intense about your work. You can turn on the afterburners when you need to.

It doesn't just mean kids. It's picking up your parents at the airport when they get in from out of town. It's going to a friend's extended birthday weekend. It's being at the parent-teacher conference or whatever it is. And I think there's too often an image of a sometimes performative grind in certainly Silicon Valley startups.

It's not that we don't believe in hard work. Boy, do we. Again, intensity. But it's in working smart and finding some balance that gives you space for—again, translate family to things that matter to you in the sense of your whole being beyond just work.

Harry Stebbings

Are you literally able to work as hard, though, when you have a family and you have 4—I mean, Clay, mate, 4 kids? That's a lot of kids.

Clay Bavor

I find I work a lot. Of course, if you just magically handed me 15 hours in a week that I wasn't with kids, I could probably do something with those. I find I am intensely focused and efficient. Boy, do I get a lot out of every hour I have.

One of the things I've done is spend a lot of time on 101 going to and from the office. We are all about being in person. Coming out of the pandemic, it was something of a novelty being opinionated about being in person. So I spend an hour and a half, sometimes 2, on the road every day.

I now have a very complex networking setup that combines 2 cellular networks and a Starlink Mini so that I have uninterrupted, beautiful connectivity to and from the city every day. You're efficient. You get everything that you can out of every hour.

Harry Stebbings

Why are you so opinionated about in-person?

Clay Bavor

In particular for a young company, I think it is—I won't say impossible, but very challenging—to build a culture, a set of shared norms, and camaraderie. So many of the things we talked about, like enterprise software as a team sport, feel great when you're part of an amazing team, and it's different when your connection to that amazing team is via a Brady Bunch of Zoom squares.

We have rituals that we've developed that we only would have developed if we were all working in person. I think, for younger employees, apprenticeship and mentorship happen. So much of what I learned, and I think so much of the initial conditions of my career, came from experienced people taking me under their wing or letting me, in some cases, literally look over their shoulder at how they were doing something.

I think there's an element of paying it forward that's important, and in-person has a role to play in that as well. There's a talk that I love by the renowned computer scientist Richard Hamming, “You and Your Research.” For any new graduate, it's probably the single best thing, on a per-word basis, that you can read. One of the central theses is: Find great people, work with them, and learn from them. It sounds obvious, but there's something deeply correct about it. How do we learn as human beings? We observe someone doing something, and we effectively copy it.

So find great people and copy them. That's how you accumulate skills and capabilities. One of the other points Hamming makes in this talk is that knowledge and hard work are like compound interest, and we all know that the earlier you start saving, because of the miracle of compound interest, it can massively change the trajectory of your life. And so any young person should be intensely focused on learning as much as they can as early as they can, locking in those lessons and capabilities, if you will. Because it is literally trajectory-changing.

Do you want to hear 2 funny things? One, we used to do 5 shows a week. I just worked harder than anyone else when I was starting out.

Clay Bavor

That's a lot of shows, Harry.

Harry Stebbings

Yeah, it was 11 years ago, but it was 5 shows a week. And two, I didn't have 1,000 listeners per show for 3 years, and I never made a dollar on the show for 3 years. It was never about money or recognition. I only cared about using this as a method to learn from you, and especially when I was 18, it was harder to meet amazing people. So I completely agree with those 2.

There are a lot of young people today. You have kids; I can picture them leaving university, uncertain about where the world is—

Clay Bavor

Yeah.

Harry Stebbings

—what to do. What would you advise them, knowing all that you know?

8. The AI Native Advantage

Clay Bavor

The obvious tsunami that's coming is AI. What are the implications for jobs? I think there's been a lot of concern, understandably, about what happens to entry-level jobs. How do you apprentice, and so on?

I think the unfair advantage that young people have coming out of university is that they've just had 4 years to spend effectively unlimited time. You've got to go to class and pass some exams and stuff, but you have huge control over your time and disposable hours. Coming out of university as a master of these AI tools, let me point you to 1,000 companies that would love to have you infuse what you know into how they're doing things.

I can't remember a time when a young person with no work experience but with the right mindset and experience using some of these tools has ever been so valued. Some of our most effective employees at the entire company are 22 or 23 years old and have been completely AI-pilled, with a comfort and facility with these tools that many of our more experienced folks don't.

Harry Stebbings

Has the way that you hire changed for the profile that wins in this AI-pilled world?

Clay Bavor

Yes. We completely changed our engineering interview process. It now looks much more like this: Here's a kind of prompt: Think through an application you would like to build. Cool. Okay, here's $150 to spend on—choose your coding agent. You can use whatever setup you want. Use whatever tools you want. Bring your own laptop, bring your own tools. We're going to pay for your tokens. And then build it.

Tell us how you went through building it, and so on. So at least in engineering, it is an AI-native interview. Of course, we test for architecture, systems design, product thinking, culture, smart, nice, intense—the extent to which we think people manifest our values. But that's changed very significantly. I will be disappointed if, in no more than the next 2 months, not every one of our interviews has some strong AI-native component to it.

Harry Stebbings

Do you think we are entering a golden age for cyber and for cybersecurity, given the proliferation of code generated by AI that may not be as secure as it needs to be?

Clay Bavor

In terms of importance, it's obvious to me that it has never been more important, given that the kind of offensive capabilities have just ratcheted up 5 notches. I think cybersecurity seems like a pretty good bet to me. The question is whether the offensive tools turn out to be defensive tools if actually Mythos and Codex 55 cyber, if they themselves are the solution, not a more narrowly focused cybersecurity product.

Harry Stebbings

What was the most recent disagreement you and Bret had?

Clay Bavor

A couple of weeks ago, we were trying to figure out how to get something to move much faster in one space. Interestingly, we basically always converge. We're highly truth-seeking. We have a funny expression.

It's like, “This is correct.” Okay, what does that mean? From some objective, truth-seeking perspective, this is the right way to do it. So we try to get to: What is the correct solution? I was on one side: “I think we need better kind of process and structure around this thing.” Bret was on the side of people: Maybe we need different leaders, or a different leader in this space.

The answer, as with most things, turned out to be some of both, right? Turned out to be some of both. We started from the idea that it couldn't just be solved with people. No, it's not just people, and we pulled on those threads. This wasn't “think apart, think together” so much as just interrogating each other, again, with the goal of getting to the right and best approach to something.

Harry Stebbings

When Bret says something, what are you like, “Yep, I'm sure. He's a G at that”? And when you say something, is Bret like, “Yep, Clay is the expert”?

Clay Bavor

Rather than dividing up the company, we think about majors and minors for every part of the company. Bret's majors are definitely sales and then engineering. He is really good at selling software. He is really good as a software engineer still. I major in what I've called the running of the company: operations, finance, legal, and so on.

I do a lot of first calls. He understands our most important contracts for things that are highly consequential in how we run the company. We have 2 nuclear keys that we turn on for those. Bret, having spent time at Salesforce, really learned from the best. Mark is extraordinary.

Harry Stebbings

Is that a sell?

He's the best seller I've ever met.

Clay Bavor

Unbelievable.

Harry Stebbings

Yeah.

Clay Bavor

The GOAT. The GOAT. Unbelievable.

Harry Stebbings

How's the weather, Mark?

Clay Bavor

Have I told you about Agentforce?

But, honestly, respect when it comes to instincts on how to sell. It's, “Yep, okay, makes sense.” Bret's instincts on system design and architecture are second to none, and so I trust his judgment more than I trust my own. On people stuff, on building and running the company, whatever Clay says, I would go with that. So I think that's probably the rough yin-yang major-minor split.

Harry Stebbings

Dude, I would love to do a quick-fire round, if it's okay.

Clay Bavor

Yeah, let's do it.

Harry Stebbings

What was your biggest lesson from working with Sundar?

Clay Bavor

It's such a gift. Sundar has a remarkable ability to look at a problem from wildly different zoom levels. His dynamic range in thinking is second to none: zoomed all the way out, at the highest level of strategy—how is this gonna unfold over the next 5 years?—all the way into the details, the pixels, right, the drop shadows, the sound, the texture of something. And I have tried to emulate that.

Talk about surrounding yourself with great people or having the privilege of working for someone. I observed a leader who is extraordinarily focused on the product, the work, and building something great, and is also just a wonderful human being, deeply focused on the humanity and folks around him.

Harry Stebbings

What does no one know about Google that you think everyone should know?

Clay Bavor

What people underestimate about Google is that when you have the alignment of an ambitious, enduring mission, incredibly smart people, and a culture that values truth and building in service of that mission, that company can kind of solve anything. People sometimes criticize Google for “1,000 flowers bloom.” If you have smart, well-meaning people caring for every one of those flower beds, and they're directed in the right way, it is quite a force for invention and discovery and building new things.

Harry Stebbings

I got asked to ask you about your book list.

Clay Bavor

Oh.

Harry Stebbings

I hear you read a lot. That's a shit question. Forgive me for it. What's the must-read for me leaving this conversation?

Clay Bavor

Oh.

Harry Stebbings

Give me one.

Clay Bavor

David McCullough's The Wright Brothers. It's so good. It's so good. It's a tight history of, obviously, the invention of the first heavier-than-air aircraft. And to me, it is as accurate a portrait of entrepreneurship and invention as has been written anywhere.

The aircraft could not have existed without this kind of network of pre-existing inventions, most importantly, a lightweight internal combustion engine. And then it was: try, it didn't work; try, it didn't work. There are scenes of them stuck out in North Carolina being eaten alive by mosquitoes. It's the hardship and then the triumph of having built something that flies.

Harry Stebbings

I've never said this before on a show, but have you seen a wonderful film called Those Magnificent Men in Their Flying Machines?

Clay Bavor

No.

Harry Stebbings

I'm gonna send this to you.

Clay Bavor

Okay.

Harry Stebbings

It is about mankind's pursuit of flight.

Clay Bavor

Sounds good.

Harry Stebbings

It's amazing.

Clay Bavor

Fantastic.

Harry Stebbings

Well, thanks for the tip.

Harry Stebbings

It's like the 1940s, '50s.

Clay Bavor

That's great. I'm looking forward to that one.

Parenting.

Clay Bavor

Mm.

Harry Stebbings

4 kids and an unbelievable operator-founder. What's your biggest advice?

Clay Bavor

First of all, having kids is the greatest gift. It is such a privilege. There are a few things I would say. First of all, you will be a changed and different person on the other side of holding your son or daughter.

It is, in my opinion, the single fastest rate of change, the single biggest change that anyone experiences in their life after they themselves are born—welcoming your first child. I try to carve out time for family dinner. We have many Sunday mornings—maker mornings—with 2 of my sons, where we block out an hour or 2 and build something at home.

And so, it comes down to rituals and discipline around making time and space. Anything important in life, in my view, is a product of clear goals and good habits. And so I think if you have a clear goal around how you want to be as a parent, and then habits that help you build towards that, I think that's a very important ingredient.

And then the other is making kids' interests your own. I'm terrible at basketball. My oldest son is an incredible basketball player. I am so proud of him. I go and watch him play, and he does things I could never do. Not only can't I do that, I could never do that.

And so I follow the playoffs. I've learned about the sport. I've learned about the best players. I've learned about coaching so that I can try to enjoy and support him in this interest more fully than I otherwise would be. And so I think for each of our 4, it's about being aware of what gets the synapses going for them, what they light up about, and then making that interest my own.

Harry Stebbings

Would you say that's the same for your partner? Do you need to have aligned interests in a partnership, in a marriage, or is it good to have different ones?

Clay Bavor

I mentioned I'm married to my high school sweetheart. We will have been together for almost 30 years, and I'm not that old. I think a great marriage is a partnership. A partnership means you are working in pursuit of, in service of, some shared set of goals.

You asked about interests. I think having shared interests in what you are pursuing as a partnership is deeply important. Those goals include happy kids who grow into adults who can enjoy their lives and contribute meaningfully to those around them, building a set of values in one's family that are aligned with your own, and ensuring, as part of that partnership, that the other member in it themself thrives and fully realizes themself.

Their interests may be different, but there can be a shared interest in enabling each other to become the best that you're able to become.

Harry Stebbings

Final one for you, but I do like it. What's the kindest thing that anyone's ever done for you?

Clay Bavor

I feel such gratitude to my parents. I'm sorry if it's a straight-down-the-fairway answer. My father was a career cardiologist. My mom's a quite talented quilt maker. Neither of them were in engineering or technology, and they saw that when I got ahold of my first computer, I just lit up.

Not really understanding what computers were about, my mom was good with them in the '80s, but it was not at all clear where they would go. But they could see that I was obsessed with them. They supported that interest to the hilt.

I remember going with my mom and dad to buy an early Power Mac. My dad was pushing: “Would you be able to do more if we had more memory in it?” I think I would be. And it's like, “Well, we should get more.” I was like, “Is this real life?”

My mom would take me out of school 1 day a year, and we would go to Ken's House of Pancakes and get breakfast. She would make up a doctor's appointment or something for me, and then we'd go to Macworld. I would get to spend the day at Macworld, which for me was like nirvana.

And so I feel such gratitude to them for seeing in me that interest and how I lit up about this thing that was unfamiliar to them, but that they then pushed and enabled. And, of course, there's a direct line from that to 18 wonderful years at Google, starting Sierra, and to today.

Harry Stebbings

They must be very proud of you.

Clay Bavor

I think they are. I know that they are.

Harry Stebbings

The thing that strikes me from this show is—I don't mean to be sycophantic; it's just—what a good person you are.

Clay Bavor

Oh.

Harry Stebbings

Do you know what? I interview a lot of people, and they're brilliant, and they're intellectually brilliant.

You obviously are that. But what strikes me is what a genuinely good person you are, which is really very tangible. I really can’t thank you enough for doing this. You’ve been an incredible guest.

Clay Bavor

Thank you so much, Harry. I really appreciate it.
