- Jeff Dean is leaving Google — where he has worked since 1999 as its 30th employee — to serve as CEO of the new AI startup Discovery Loop.
- Discovery Loop co-founders Sanjay Ghemawat (Google senior fellow), Quoc Le (Google Brain founding member), and Oriol Vinyals (Google DeepMind senior research scientist) are departing with Dean.
- Discovery Loop is structured as a public benefit corporation that aims to run thousands of simultaneous experiments, with longer-term ambitions of recursive self-improvement — AI systems that build more powerful AI without human iteration.
- Alphabet (Google's parent) is among the financial backers, with the initial round co-led by Radical Ventures and Khosla Ventures and participation from Kleiner Perkins, Lightspeed, and Doerr Capital.
- Dean previously helped build Google's core search infrastructure — crawling, indexing, and query-serving — and had significant influence on Gemini's multimodal models, per his career history at the company.
Why it matters: Google loses its longest-serving technical leader and at least three other top AI researchers to a startup targeting automated scientific discovery. Alphabet's decision to financially back a company founded by its own departing executives is unusual — especially given Dean's key role shaping Gemini's multimodal models.
