# Matan Grinberg

> Matan Grinberg is the CEO and Co-Founder of Factory, an AI platform that deploys autonomous agents called Droids to automate the entire software development lifecycle. A theoretical physicist who dropped out of his UC Berkeley PhD program in 2023 after a fateful three-hour walk with Sequoia partner Shaun Maguire, Grinberg built Factory from a 72-hour hackathon demo into a $1.5B unicorn backed by Khosla Ventures, Sequoia, Blackstone, and Insight Partners. Named to Forbes 30 Under 30 AI in 2025, he is one of the defining voices in the agent-native development movement.
