Last week I studied the first Founder Profiles, twenty founders who started $5B+ companies at or before the age of 23. This week I went through the second volume: twenty-five founders, same $5B+ threshold, but older at founding, between 24 and 29. Published October 2025 by @kokoxsu.
The names: Vlad Tenev, Tobi Lutke, Brian Armstrong, Brian Chesky, Jack Dorsey, Tony Xu, Ben Silbermann, Drew Houston, Apoorva Mehta, Tom Preston-Werner, Pavel Durov, Ivan Zhao, Howie Liu, David Helgason, RJ Scaringe, Viktor Jacobsson, Guillaume Pousaz, Tan Hooi Ling, Max Rhodes, John Zimmer, Sachin Bansal, Niraj Shah, Ara Mahdessian, Josh Reeves, Rob Kalin.
I'm a believer in out-of-distribution individuals. I think they're the best early signal you can find in a person, better than school, better than prior company. Most of these founders would have been rejected in a traditional hiring process. Some barely have a resume at all. Each of them built a generational company anyway.
So what does out-of-distribution actually mean? I think it comes down to three things: trauma, neurodivergence, and polymathic range. Nearly every founder in this set carries at least one. The best carry all three.
The world broke something in these people when they were young, and the scar tissue became load-bearing.
Vlad Tenev was born in communist Bulgaria. His father left for America when Vlad was a toddler, and they were separated for two years. When the family reunited, they were broke, living in student housing, Vlad tagging along to his dad's campus computer lab because there was nowhere else to go. Back in Bulgaria, his grandparents watched their savings evaporate in hyperinflation so severe that relatives melted copper cookware as a store of value. Robinhood's entire premise is that finance shouldn't be gated. That premise came from somewhere.
Ara Mahdessian was born in Tehran during the Iran-Iraq war, close enough to hear the bombs. His family fled to California when he was a toddler, and his father became a plumber who struggled with the paperwork of running a small contracting business (language barriers, no good software). Ara grew up watching that struggle, then built ServiceTitan for exactly that kind of trade worker. He didn't discover the problem. He grew up inside it.
Tony Xu emigrated from China at five. His mother worked in a Chinese restaurant, and by nine he was washing dishes beside her, bussing tables, tinkering with the broken cash register. He built DoorDash. Brian Armstrong spent a year in Argentina after college and watched hyperinflation wipe out ordinary people's savings in real time; he came home and built Coinbase. Brian Chesky's parents were social workers, and he couldn't make rent in San Francisco, so he inflated air mattresses for strangers. Three people showed up, and that was the first night of Airbnb. Apoorva Mehta was born in Jodhpur, lived in Libya as a child, then landed in freezing Hamilton, Ontario at fourteen, hating every trip his mother sent him on to the grocery store. He built Instacart. Pavel Durov grew up in St. Petersburg with a philology professor father and a math prodigy brother, but spent formative years in Turin, uprooted by his father's academic postings, always the outsider. He built Telegram, a tool for people who don't trust institutions with their conversations.
Trauma gives you two things that are hard to get any other way. One is an emotional relationship to a problem, not a market analysis but a feeling in your body that something is wrong. The other is a tolerance for pain most people don't have. Starting a company is brutal, and most people quit. The ones who don't have often already survived worse.
Not diagnosed, necessarily, but a brain that clearly runs differently, one that fixates, processes sideways, can't sit still inside conventional structures.
Tobi Lutke never got a university degree. Teachers flagged him with learning disabilities. He worked out the bare minimum effort needed to pass his classes so he could go home and code, self-taught and programming by eleven, soldering new parts into his own computer. School simply couldn't hold him. He built Shopify out of an online snowboard shop because no e-commerce platform available was good enough for what he wanted to do.
Jack Dorsey had a speech impediment as a kid and was quiet enough that teachers might have overlooked him. But he was listening to everything, obsessively tuning into his dad's police scanner, tracking dispatchers, fascinated by the pulse of a city in real time. At fifteen he wrote dispatch software that taxi companies used for years. He dropped out of NYU, and after getting fired from Twitter he spent a year training as a massage therapist and taking fashion design classes, sewing pencil skirts, before coming back to build Square.
Rob Kalin might be the most extreme case in the whole set. His parents divorced, he was bullied, and he graduated high school with a 1.7 GPA. He faked an MIT student ID, conned his way into NYU with a professor's recommendation letter he had no business having, and bounced through five colleges. Along the way he was a cashier at Marshalls, a stock boy in a camera shop, a demolition laborer, a personal assistant to an elderly philosopher. At sixteen he left home for an artists' squat in Boston. He built Etsy in ten weeks from a Brooklyn apartment because he couldn't find anywhere online to sell what he made with his hands. Even the name was an accident: he misheard actors in a Fellini film saying "eh, sì" and liked the sound of it.
Drew Houston was programming by five. At fourteen, frustrated with bugs in a video game, he dug into the source code, found security vulnerabilities, and emailed the developers explaining how to fix them. They hired him on the spot; his dad had to co-sign the paperwork. Howie Liu taught himself C++ at thirteen from a manual in his father's office, enrolled at Duke at sixteen, and was acquired by Salesforce by twenty-one. David Helgason crashed his mother's computer trying to run games, taught himself to fix it, and took a café job that paid mostly in free meals so he could build Unity's engine for no salary.
None of these were people succeeding inside the system. They were people the system couldn't classify, which is a large part of why they were able to build new systems.
The third axis is the accumulation of skills and interests that look incoherent on paper but combine into something sharp.
Ivan Zhao grew up in Urumqi, in China's Xinjiang region, competing in the International Informatics Olympiad while training in traditional Chinese watercolor painting. When his family moved to Canada, he learned English watching SpongeBob SquarePants, then studied cognitive science at UBC instead of computer science because he cared more about how humans think than how machines compute. Notion feels like a design object rather than enterprise software because Zhao carries both an engineer's precision and an artist's eye, a combination that doesn't come out of a standard CS track.
Brian Chesky went to art school at RISD. He was a hockey kid who slept in full gear on Christmas night, sketched redesigned Nike sneakers for fun, and spent hours in museums reproducing paintings. He came from industrial design, from the belief that you improve any experience by redesigning it from the human outward, which is why Airbnb never felt like just a marketplace with a decent UI.
Ben Silbermann grew up in a family of doctors in Des Moines, everyone expecting him to become one too. At eight he was pinning dead insects to cardboard, collecting and organizing by category. He went to Yale, worked at Google, then quit to build what he actually cared about. Pinterest is a straight line from that childhood impulse to collect and arrange beautiful things, not the product a typical Google PM would build, because he was a bug collector from Iowa who happened to know how to code.
Tom Preston-Werner turned down a $300,000 retention package from Microsoft to go all-in on GitHub, writing on his blog that he'd rather say "that was an adventure" than "I sure felt safe" when he's old. Dorsey moved between code, dispatch systems, fashion, massage therapy, and botanical illustration before settling into his groove. Guillaume Pousaz dropped out, went surfing, then bootstrapped Checkout.com for seven years without outside funding just to prove the model could work.
None of these people are generalists in the corporate, well-rounded sense. They're idiosyncratic, pulled in several directions by genuine obsession, and it's the specific combination that lets them see what other founders miss.
Most of venture capital pattern-matches on distribution: Stanford, Y Combinator, prior founding experience, a clean narrative. These twenty-five profiles suggest the highest-impact founders often sit outside that distribution entirely. The kid who faked an MIT ID. The founder with no degree who emigrated for love. The boy from Xinjiang who learned English from cartoons. The toddler who fled a war zone and grew up watching his father struggle with invoices.
The traits that make someone a great founder (pain tolerance, obsessive focus, an inability to accept broken systems, the cross-domain vision that comes from living between worlds) are often the same traits that make them look like bad bets on paper. The system that produces $5 billion companies isn't the system that produces impressive resumes.
Seventy-five investors told Vlad Tenev no before someone said yes. Chesky sold cereal boxes to keep Airbnb alive. Lutke couldn't get a programming job in Canada. Kalin had a 1.7 GPA. Viktor Jacobsson and his Klarna co-founders got laughed out of their university's startup incubator and turned down by more than twenty investors before an angel named Jane Walerud finally wrote a €60,000 check.
The founders who build the biggest things aren't the ones the model predicts. They're the ones it misses.
