He was a Princeton-trained theoretical physicist who once co-authored a paper on black hole singularities with one of the most celebrated minds in the field. Then Matan Grinberg walked away from his PhD, and 72 hours later he had a demo of a company. Today Factory is a $1.5 billion enterprise valued for its "Droids" — autonomous AI agents that do the software engineering work developers dread. This is the story of a physicist who traded string theory for a very different kind of fundamental problem.

Scott Wu spent his teenage years winning gold at the world's hardest programming contests, then walked away from Harvard, from a first startup, and from the safety of the crowd to build a machine that writes code. In November 2023 he co-founded Cognition and, four months later, unveiled Devin, the first "AI software engineer." By mid-2026 the company was worth $26 billion and its own AI was writing the overwhelming majority of its code. This is the story of how a competitive-programming prodigy tried to give every engineer a tireless partner rather than a replacement.

Mark Pincus spent more than a decade launching companies that fizzled before he built one of the most talked-about businesses of the social web. Zynga — named after his late American bulldog — turned casual games like FarmVille and Words With Friends into a cultural phenomenon and a multibillion-dollar company in barely four years. His story is a study in persistence, uncomfortable honesty about growth, and the hard lesson that founding a company and running a public one are two very different jobs.

The startup with fifty employees is quietly being replaced by the startup with fifty agents. A new kind of company is emerging — one where AI agents don't just write code, but run their own apps and tasks across discovery, building, and marketing. Here is what the agent-run company looks like, and why the next wave of founders will start this way.

AI app builders can turn a prompt into a working product in minutes — which is genuinely useful, and also where most people stop thinking. But shipping an app is roughly ten percent of running a company. Here is the difference between an AI that builds your app and an AI that discovers, builds, and markets your entire business.
