Keith Rabois on Barrels, Undiscovered Talent, and Why He Won't Let Colleagues Talk to Customers

Open on YouTube ↗
Overview

Keith Rabois has worked at the center of several defining Silicon Valley companies. He was an executive at PayPal, COO at Square, and VP of Corporate Development at LinkedIn. He was an early investor in Stripe, Palantir, Airbnb, YouTube, DoorDash, and Ramp, and he is now a managing director at Khosla Ventures. In this conversation with Lenny Rachitsky, the central question is how companies build world-class teams, and how that changes as AI reshapes the work. Rabois's position is consistent and often deliberately contrarian. He believes team quality determines almost everything. He thinks the best talent is usually undiscovered. He argues that success should bring more pressure, not less. And he holds that consumer companies should stop asking customers what they want.

An iPad-only life since 2010

The conversation opens with a detail about how Rabois works. He was on an iPad, and he said he hasn't touched a computer since September 2010. When he joined Square, Jack Dorsey was running the company from an iPad, and Rabois converted immediately. Since then, he said, everything he does happens on his phone, his watch, or his iPad.

Lenny compared this to the recent trend of engineers such as Boris Cherny and Simon Willison coding from their phones by talking to AI. Rabois said he tries to stay ahead of the curve and joked that following Steve Jobs keeps you in good shape in technology. His reasons are partly about avoiding distractions and mostly about portability: the weight, the flexible screen angles, and being able to carry it everywhere. Unless you are doing heavy engineering, which he noted has not been his forte "although I may have to start," he sees no reason to use a heavier, less flexible machine.

"The team you build is the company you build"

Asked what the best companies do to attract top talent, Rabois went to first principles. The most important lesson he learned at Square came from Vinod Khosla, who sat on his board: the team you build is the company you build. People get distracted by the market, customers, product, and technology, he said, but with the right people everything else becomes easy, and with the wrong people everything becomes difficult.

He said he actually learned this at PayPal before Khosla put it into words. He explained PayPal's success, and the string of companies its alumni founded over the following 25 years, by the fact that Peter Thiel and Max Levchin gathered an extraordinary density of talent. Levchin hired essentially all the technical staff and Thiel hired nearly everyone else. Both relied mainly on their networks. It was very hard to get a job at PayPal without a first- or second-degree connection to the engineering team or to Thiel through Stanford. Rabois said this model works very well if your network contains unique talent, and that interviews are not a great substitute for it. He would not recommend it to everyone.

Learning to hire: from 50/50 to recruiting inside the building

Rabois admitted he was mediocre at hiring early at PayPal, roughly 50/50 between good and mediocre hires. That doesn't let you scale a team with an unfair advantage. David Sacks, then COO, told him he would not be promoted again until he demonstrated leadership leverage. Sacks had an equation for this: 1 + 1 must equal three or more, meaning each additional hire must produce disproportionate, non-linear returns.

Since his external hiring wasn't working, Rabois looked inside PayPal. He found people he thought were talented but underused relative to their potential and ambition, and he recruited them onto his team. It worked. The team got up to speed fast, produced important results, and he was promoted fairly quickly. The lesson he took was that he could identify talent. He just couldn't identify it in strangers. With people he had lunch with, ate dinner with, or ran around the PayPal campus with, his judgment was accurate. In a 20-to-45-minute interview, it wasn't. So his first move was to double down on people he knew. Over the following years he developed separate techniques for assessing strangers, which he said is unavoidable if you want to build an organization or invest as a VC.

He believes some of this can be taught to founders. He made a strong claim about its importance: if a founder shows early in their career the ability to assess talent "ruthlessly and accurately," they can go very far with no other abilities at all. He described hiring as a muscle. You try, study what worked and what didn't, work out what you could have known and why you missed it, and iterate.

He was careful about how far tactics can take you. In his view, tactics move you meaningfully within the middle of the bell curve. They cannot teach you to identify the top 10 to 50 basis points of talent. For that you have to deviate from the norm. If a playbook could get you there, by definition many people would be in the top 10 basis points.

Tactics that do help: references, framing, and a 30-day check

The first teachable skill Rabois named is what he calls ruthless referencing. It works less well for new graduates, whose references carry less context. His example was Tony Xu at DoorDash, who, Rabois said, does 20 references on every senior hire. He also described a rule David Sze taught at Greylock: keep referencing a founder until you hit a negative reference. Only then do you know you've exhausted the references.

Framing matters too. He illustrated this with Faire, where he has invested since the seed round. Faire was founded by former Square colleagues, including Max Rhodes and Jeffrey Kolovson, who had worked for him. According to Rabois, many VCs checking Rhodes's references asked whether he had been a good employee, and the answers were very mixed. That made some very good investors nervous. Had they asked whether Rhodes could be a world-class entrepreneur, he said, the answer would have been yes. Same person, wrong question, wrong result. Many passed on Faire and now regret it, even though they were calling people like Jack Dorsey for references.

For senior leadership candidates, Rabois always asks: "If you were CEO, what would you have done differently?" about the candidate's current company. He said the point isn't to get them to criticize their employer. He wants to see how much of the business model they've absorbed, whether they understand trade-offs, and whether they have ideas that could create an unfair advantage. His follow-up question is: why weren't you able to persuade the CEO to do it? In reference calls, he generally probes two things: what would make this person most successful, and, if things didn't work out, what the primary root cause would be.

Lenny noted that most people hire and then learn little from the outcome. Rabois cited research he had read: asking yourself, 30 days after any hire, whether you would make the same decision is about as accurate as evaluating a year or two later. That gives you a tight feedback loop, and you can ask the whole hiring team the same question. He said every company should do it.

15:44

Barrels and ammunition

The best-known framework in the conversation came out of a pattern Rabois kept seeing. A company raises a Series A or B and hires many people. Burn goes up, but output per week or quarter doesn't. After years of hearing frustrated CEOs describe this at dinners and in one-on-ones, he concluded that very few people in any company can independently take an initiative from inception to success. He calls them barrels. Hiring more people without adding barrels just stacks people behind the same initiatives. That adds coordination and collaboration tax, which creates drag.

He gave numbers. By his count, PayPal had about 254 people in Mountain View when it was acquired. Depending on how strict you are, it had 12 to 17 barrels, which he called "like an infinite number" and attributed to its exceptionally talent-rich network. He once asked Jack Altman how many barrels were at Lattice, which he called a big company, and the answer was two. Rabois said that is the more common answer, even for a very good company. The number of barrels, typically somewhere between two and fifteen, sets how many things a company can do in parallel or in sequence. More hiring doesn't change it and may reduce output.

He does not dismiss ammunition. Some projects need a designer, engineers, a PM, and analysts. Others can be done by a barrel alone. What matters is thinking deliberately about the ratio of ammunition to barrels for the problem at hand. That ratio, he said, determines how many important initiatives a company can pursue at once.

What makes someone a barrel: the smoothie test

Rabois defined a barrel simply. Point at a hill and say "get us over that hill." A barrel will motivate people, gather resources, and measure whatever is needed to get the company there. Anything less is not a barrel. The scope starts narrow and grows as trust builds. Sometimes the barrel has no idea how to solve the problem at the start. The core skill is "I'm going to take this off your plate": the CEO can fire and forget. If it isn't going to happen, a barrel comes back proactively, with enough time for the CEO to help, and explains the obstacles, what they've already tried, and their diagnosis of the root causes. Lenny suggested "agency." Rabois agreed it fits but said words like that tend to go in one ear and out the other, like "strategy."

His example was what he called the smoothie test, which he had described in a 2014 YC lecture. Square engineers often worked late, and he wanted them to have healthy food rather than junk food, specifically cold smoothies delivered at 9 p.m. Square had a sizable office team and executive assistants, and every attempt failed. The smoothies came warm or late, and then nobody could rely on them. He mentioned his frustration to an intern, Taylor Francis, on Francis's second day, and Francis said he'd solve it. Rabois was skeptical. The next night at 9 p.m., cold smoothies that tasted great showed up on the standing desk where the engineers gathered. Rabois said he thought, "Oh my god, I found a barrel," and later gave Francis almost everything to do.

Winning over proven talent, and building on undiscovered talent

For attracting people with proven talent who have multiple offers, Rabois said the standard pitch still matters: selling the mission and vision is indispensable. His more nuanced approach is to show a candidate that their specific skill overlaps with the company's critical blocker, so they are betting on themselves. If the company's main blocker is marketing, not product or technology, you can tell a world-class marketer that they are uniquely positioned to solve it.

That is how he ended up at Square. In 2010 he had just been acqui-hired into Google and planned to become a VC once his compensation vested. Square's investors called and said they had spent nearly a year looking for someone who understood financial services and was still entrepreneurial, and that there were only two or three such people in the world. That argument got him to leave Google after two weeks, which he said infuriated everyone, and to put off venture for three more years. Lenny wondered whether this was ego. Rabois called it impact: talented people want to be challenged and to do things that really matter.

His more important point, though, is that companies should be built on undiscovered talent and avoid competing for the people everyone wants. He said Thiel taught him this in his first week at PayPal, on a jog around Stanford: finding undiscovered talent is the only way to scale against incumbents with unlimited money. He compared startups to sports teams under a salary cap, except a startup's cap may be a tenth of its competitors'.

Asked for one tip on spotting it, he said to figure out why other people will misprocess this person. Recruiting at large organizations becomes a homogeneous black box, so he asks what Meta, Google, Block, or Coinbase would miss about a candidate, and why. Sometimes the answer is simply a lack of data. He acknowledged this can sound controversial, but said his approach tends to skew toward younger hires. The reason, in his account, is not that youth is the goal. Younger people have fewer data points. He compared it to credit scoring: past 30, there's enough data on you that the black box will process you like many others. With few data points, a homogeneous evaluation struggles, and that is where the "alpha" is. Lenny noted this is essentially the same skill as picking startups, and Rabois agreed.

27:55

Why the CEO should push harder when things go well

Lenny read a comment from someone who has worked with Rabois: no matter what numbers a team puts up, he pushes for more, and often pushes harder the better they do. Rabois agreed. He cited a story in which a CEO friend asked Mike Moritz what the best CEOs have in common, and Moritz answered, "the relentless application of force." Rabois said success breeds complacency, and the CEO's single role is to offset it. Unless you've built a network effect, which most businesses haven't, you can't afford to coast.

He added that as a board member he deliberately inverts his behavior. When a company is struggling, he is usually non-critical and acts more like a coach, because the founder already knows things are bad and criticism doesn't help. When a company is thriving and borderline complacent, that's when he identifies what will eventually become problems. He compared this to a good sports coach: polish the details while you're winning, and sell the future while you're losing. He also used the Super Bowl as an analogy. After a championship season, the record resets to zero. He said venture is like that too. He has had about 13 years of strong investments, but it doesn't matter if he doesn't find the next undiscovered founder.

Lenny said he saw this with Brian Chesky at Airbnb, and that during brief lulls morale actually dropped. Rabois said he agrees with nearly all of Chesky's views and called Lenny's observation subtle and important. Really talented people are like superb athletes with an internal tempo, and when everyone is coasting, the best people become unhappy.

Careers in the AI era: curiosity, and the CMO as top token consumer

On the anxiety in the job market, Rabois said AI will radically reorient many careers, "maybe including mine." His advice is to be intellectually curious. He does believe in working hard and in "no days off," but he sees curiosity as the way to future-proof yourself. His evidence was an observation from two large companies he is close to, both with many engineers, one of them Opendoor: the number one consumer of AI tokens is the CMO. According to Rabois, these CMOs sometimes build what used to be called analytics, sometimes produce actual campaigns, and sometimes give the CEO insights directly. They no longer have to go through "deputies and deputies and deputies" to get work product. He said this is very encouraging, especially for executives.

35:27

The product triad: why the PM role makes less sense

Rabois said a podcast featuring Peter Fenton convinced him that the traditional PM role makes little sense in the future. In his description, a PM gathers customer inputs and builds an organized, sequential roadmap for the next year. He believes that world no longer holds, because foundation models are improving so fast that a year-long roadmap is incoherent. Things impossible in November are easy by March. Companies need to change their roadmap almost on the fly, and intermediaries like conventional PMs fit poorly with that. Someone needs to notice that something is newly possible this week and exploit it by shipping new value next week.

Lenny pushed back. As AI eats the middle of the development process, the remaining hard part is deciding what to build and aligning people around it. Rabois agreed, but said that skill now looks more like being a CEO, "what are we building and why," regardless of whether the person was a PM, designer, or engineer. He cited Alfred Lin's analogy of a top chef who doesn't cook every dish but samples and edits others' work. Half of that chef's job is commercial: value proposition, differentiation, brand, segment, pricing, even location. Rabois summed up the enduring human skill as business acumen: understanding the company's business equation and being able to create things that move the needle on your own.

Lenny argued that great PMs are historically best at this. Rabois said that's true for exceptional ones, but many great engineers have always had strong commercial instincts. He named Max Levchin, whose instincts he called "on steroids," and Jeremy Stoppelman, who had them as an individual contributor at PayPal before founding Yelp. Rabois expects AI to put a big premium on such engineers because they won't need large teams. His example was a friend who is a director of engineering at Ramp. That person manages about 20 people and, according to Rabois, personally ships as much code as he did as an IC, using AI as a kind of second team that he directs.

41:15

Design and code are merging

On design, Rabois said design and code are merging. It isn't clear to him whether code will become design or design will translate automatically into code. He said he has made investments that bet on both, but either way they are no longer separate fiefdoms. Lenny said his own analysis shows open design roles have been flat for about three years, and mentioned Jenny Wen's point on an earlier episode that there's no time for a traditional design process when engineers ship many things a day. Rabois pointed to Shopify. By his account, for about two years Shopify has not let PMs present product ideas as slide decks. Every product presentation must be a working demo, and executives refuse to look at static descriptions of features.

Lenny suggested design should become more of a differentiator as the number of products explodes, and Rabois agreed. He said the alpha lies in storytelling, not in tools, channels, or metrics, much like in marketing. It is a kind of NP-complete problem: there are countless ways to express the same idea, and the person who finds the right frame, like "a thousand songs in your pocket," is worth more than all the tools in the world. When founders pitch him, one of the first things he looks for is how the product will cut through the clutter.

45:38

AI content, AI writing, and the brief's first paragraph

Lenny floated the idea that AI content will overtake human content, and Rabois called that inevitable. He predicted a split. One pole is curated content with a premium on provenance, where people want to know something was human-made, the way people value a real Warhol even though anyone could now produce a high-fidelity copy. The other pole is algorithmic ranking of whatever is best, AI-generated or not. He compared this to Ben Thompson's framing of curation versus algorithm. On companies that simulate humans for marketing tests, such as one Lenny mentioned, Rabois's question is what they're trained on. Without the right data, he said, claiming to simulate humans is dangerous.

Lenny found it ironic that large language models seem worst at writing. Rabois's hypothesis is that labs ration tokens to make their economics work, so quality falls noticeably as output grows from a short piece to a page, a chapter, or a book. What works for him now is short outputs, many examples, editing, and re-prompting.

This led to his years as a litigator. He said he spent about four and a half years as a law clerk and litigator, and that all the magic in a brief was the first paragraph. With three weeks to write a brief, he might spend a week or more walking around thinking about the first three sentences, and the answer sometimes came in the shower or on a run. Once he had them, he could write 30 pages in two days. He sees AI as good at the "power through the rest" part. You still need the first three sentences.

He said law occasionally helps. Weighing legal risk against business risk is useful, and he said it's no accident that many of his best investments, including YouTube back in the day, are in heavily regulated areas like financial services. But he considers most legal training at odds with entrepreneurship. Law school trains issue-spotting, finding everything that could go wrong, and it's easy to list reasons a company might fail. Solving them is the hard part. Lawyers also measure productivity in billable hours. He said it took him roughly a year and a half after moving into tech to stop logging his time in a notebook. He noted that Thiel quit law after a few months and that Sacks never practiced.

51:35

Why he refuses to let colleagues talk to customers

Rabois said many of his contrarian views have since become consensus, which is what you want as an investor: Airbnb started as a contrarian bet and had to become consensus to succeed. One view that still provokes disagreement is his stance on customer research outside the enterprise. "I hate talking to customers. I refuse to allow colleagues of mine to talk to customers," he said.

His argument goes beyond the familiar "faster horses" line. He believes customer feedback is often directionally wrong. Consumer purchases are subconscious decisions, and when people try to explain them consciously, they give misleading answers even when they're trying to be helpful. His example: ask anyone who drives a Porsche or a Lamborghini why they bought it, and 99% of the time they'll give every reason except the real one. He also said a staged research setting isn't a proxy for the real world, where a product must cut through the clutter while people are at their Barry's class, working, raising kids, or riding the subway. He added that "everything important you need to learn about humans is written by Shakespeare," and called Shakespeare better than all the customer research.

He makes an exception for serious enterprise sales. There, a decision maker is making a mostly utilitarian choice, and customer development works. He described an AI company he works with whose goal for the next two years is 30 must-win accounts. It can talk to all 30 decision makers and even influence their CEOs. But for consumer, SMB, and micro-merchant products, which he sees as anything below mid-market, including businesses like Square and DoorDash, he called customer research an "unmitigated disaster." Part of the harm, he said, is that anecdotes stick. He described meetings where someone admits eight conversations aren't statistically representative and then talks about them for an hour. After that, the anecdotes shape every later meeting.

In place of customer research, he uses the analogy of a movie. The goal is to sell tickets. If you aren't selling them efficiently, go back and ask whether the trailer, distribution, casting, or script is off, much like analyzing CAC and LTV. He also separated asking customers what they want from testing feasibility. For a business like DoorDash, you might ask restaurants whether they'd display a placard, or calculate how many deliveries per hour you need to break even and whether there's enough density. What you don't do is ask ten people in Palo Alto whether they want a button on their phone.

He said the best companies rest on a foundational insight whose logic can be pressure-tested. When Tony Xu and Evan came to pitch DoorDash, their statistic that 93% of US restaurants didn't deliver convinced him. Their description reminded him of Andrew Mason's line that phones should have two buttons, "I'm bored" and "I'm hungry," and he thought they were building the "I'm hungry" button. Chesky's Airbnb pitch included the number of Craigslist posts in the Bay Area from people wanting to rent out a bedroom, about 30. Rabois considered that significant because people had to come up with the idea and type it in themselves, and he was leaning in within minutes. Had Airbnb surveyed ten random people, he said, nine or more would likely have said no.

Lenny brought up a Taylor Swift speech about spending thousands of hours developing her craft alone before sharing it. Rabois said musician friends have described a related trap: a first hit that wasn't data-driven is followed by pressure from managers or labels to gather feedback, which produces derivative, less inspired work. He mentioned a conversation between Jack Conte and Alex from The Chainsmokers about a song that failed with their core audience but found a different one.

1:01:09

Ugly babies and evaluating AI startups

Lenny raised Ed Catmull's idea that great ideas start as "ugly babies." Rabois said he uses this as an investor. When he makes a seed or Series A investment, he wants about half his VC friends to literally laugh at him. He knows most of his competitors well enough to predict this, and if they'll laugh, it may be a great investment. Lenny said research he did with Terrence Rohan on early employees at generational companies such as OpenAI, Palantir, and Stripe found a similar pattern: people thought those ideas were crazy. Rabois added that his parents laughed at most of his tech jobs and worried he'd end up homeless, though his mother appreciated Stripe and lobbied him to invest until he did.

For AI startups, the existential question Rabois named is whether the foundation labs will become so capable that nothing else can breathe. A startup has to be durable for 8 to 20 years, and the pace of progress at multiple labs raises doubts even about companies that are thriving now. His second question, one he has asked for 25 years, is what accumulating advantages the company has, something that makes the business better, and eventually easier, over time. Network effects are only one type. At seed stage he doesn't expect proof. Maybe once every five years you can point to empirical evidence that early. He wants the founder to explain conceptually where those advantages could come from, and ideally when they'd start using or measuring them.

Overall, Rabois called himself a founder-driven investor. The only question at seed or Series A is whether the founder has a non-zero chance of changing an industry or the world, and whether this could be the next Brian Chesky. He noted that other successful investors work differently. He described Marc Andreessen as more technology-driven, Vinod Khosla as a mix, and his colleague David Weiden and Sequoia's Alfred Lin as more product- and market-driven.

1:06:48

Three traits of the companies that are thriving

Asked what distinguishes his best-performing portfolio companies, Rabois named three things. The first is speed, specifically an operating tempo that shows up very early. When Roelof Botha joined Square's board after leading its Series B, he told Rabois two meetings in that he hadn't seen that tempo since PayPal: a problem identified at one board meeting would be solved, shipped, and addressed by the next. Rabois's then chief of staff, Delian Asparouhov, said after shadowing two Faire board meetings that Faire was the one company that could get him to leave venture, for the same reason. By the next meeting, the team had found the root causes of a problem, shipped a fix, and measured its effect. Rabois said that speed compounds. It is also partly why he preempted Ramp's Series A. He led the seed around May 2019 and offered a term sheet in September, because Ramp was close to shipping cards in about three months, when in his experience it usually takes nine to twelve months at best.

The second trait is a critical density of talent that visibly improves over time, so that the team becomes deeper and better than the one he invested in. The third is a hiring philosophy that mostly skips senior, experienced hires in favor of growing people internally. He said this is especially true at Ramp and Trade Republic, while allowing that there are exceptions. He cited a framework from a blog post Asparouhov wrote about lessons from Rabois: if you're hiring for value preservation, experience helps, but for value creation it probably doesn't. Some companies use the chief of staff role as a talent factory. He described a company whose board meeting he attended that week, which did phenomenally by every metric. Its outstanding CMO was the CEO's previous chief of staff, and its new head of product was the current one. Lenny mentioned Ramp's emphasis on velocity and its running day count. Rabois said every Ramp board meeting opens with the day number on the first slide.

1:12:48

Criticize in public

Rabois said he learned from a founder he works with to criticize people in public. His reasoning is that private negative feedback optimizes for the individual rather than the system. Colleagues usually already suspect a problem. Addressing it openly shows them it's being handled, lets others offer help, and turns it into team-building instead of leaving the rest of the company worried about why the problem persists.

When Lenny asked whether that creates fear, Rabois said the goal is winning. He allowed that the best sports coaches probably mix public and private feedback. He was blunt about psychological safety: "High performance machines don't have psychological safety. They're about winning." He recommended The Jordan Rules and The Last Dance: to be Michael Jordan, you have to act like Michael Jordan. Asked whether psychological safety is negatively correlated with success, he said, "For the most part."

Failure, and a partial exception on psychological safety

For failures, Rabois pointed to Slide, the company that was acqui-hired into Google. It sold for about $187 million, but he said it fell far short of its ambitions and didn't achieve its product or company goals. He said investing is mostly about failure: a 30–40% hit rate at early stage is excellent, meaning most bets fail. He compared it to Nike ads about Michael Jordan's missed game-winners and a tennis great who loses a large share of points.

He also said he tries not to dwell on failure. At a recent board meeting of a company doing well, well-meaning board members proposed retrospectives on failures, and he pushed back. He doesn't want to discourage ambitious shots on goal. He acknowledged this is where psychological safety "maybe has some validity": people should feel free to be bold and volunteer for hard problems. The exception is when something foreseeable was missed.

Lightning round

His most-recommended book is The Upside of Stress by Stanford professor Kelly McGonigal, which he said makes a compelling case that more stress, not less, makes people happier, healthier, and wealthier. He recommended Nuremberg, saying he learned several things despite being a student of history and politics, and that it holds lessons for preventing historical tragedies. He named Eight Sleep as a product he's addicted to, disclosed that he is an investor, and restated his belief in eight hours of sleep a night.

His motto is "no days off," which he traced to Bill Belichick's chant at a Patriots championship parade. He said it applies to work, including weekends, and to exercise. He said he has missed only seven workouts in seven years, still regrets several of them, posts the count every year, and missed none last year. For him, "no days off" is shorthand for not believing in excuses. Asked whether anyone from the PayPal era surprised him by outperforming, he said no. He believed he had a good sense of who had founder-level ambition, and he apologized for not having a better answer.
