# Jeff Dean leaves Google after 27 years to co-found Discovery Loop AI startup

> Jeff Dean, who spent 27 years at Google and helped build much of its core infrastructure and its Brain research lab, is leaving to start a company called Discovery Loop. He is not going alone: the co-founders include Sanjay Ghemawat, Quoc Le, and DeepMind researcher Oriol Vinyals, a lineup that represents an unusual concentration of the field's foundational engineering talent walking out the same door. Discovery Loop is pitched as a bet that AI can automate the scientific method itself. The plan is to run thousands of experiments in parallel, close the full loop from hypothesis to result without human hands in the middle, and even explore recursive self-improvement where AI systems help design better AI. The seed round is led by Radical Ventures and Khosla Ventures, with Kleiner Perkins, Lightspeed, Doerr Capital, and, notably, Alphabet itself all participating. The significance is twofold. It is another marquee departure in a brutal year of talent churn across the big labs, and it signals that some of Google's most senior scientists think automated discovery is better pursued outside a trillion-dollar company than inside one.
