Matan Grinberg left a string theory PhD at Berkeley to start Factory, betting on full autonomous software engineering in 2023.

It started with a cold email to Sequoia’s Shaun Maguire and a three-hour walk that helped convince Matan to leave his PhD and build a company. Three years later, Factory is valued at $1.5B, with recent reports putting its newest valuation north of $3.5B.

We get into: what string theory teaches you about making decisions, the three phases every company goes through with AI adoption, how to measure ROI of AI spend, why he'd take Chinese open models over a closed-model monopoly, the sleeper-agent risk hiding in open weights, what he thinks about recent security incidents from large labs, and why he believes we're already living in a post-AGI world.
