- Jeff Dean, Google's 30th employee (since 1999), is leaving the company to serve as CEO of his new AI startup, Discovery Loop.
- Sanjay Ghemawat, Quoc Le, and Oriol Vinyals — senior researchers from Google Brain and Google DeepMind — are co-founding Discovery Loop alongside Dean.
- Discovery Loop is structured as a public benefit corporation that plans to use AI to initiate and iterate thousands of experiments simultaneously, aiming to partially automate the scientific research process.
- The startup is also pursuing recursive self-improvement, using AI to build more powerful AI and remove human iteration from the experimental loop.
- The seed funding round is co-led by Radical Ventures and Khosla Ventures, with Kleiner Perkins, Lightspeed, Doerr Capital, and Alphabet — Google's parent company — also participating.
- Dean's two-decade Google tenure included core contributions to search infrastructure (crawling, indexing, query-serving systems) and to Google Gemini's multimodal models.
Why it matters: Alphabet is financially backing a startup founded by its own departing star — an unusual alignment that softens the talent loss but still drains Google of senior AI leadership. With Google funding the venture and competitors like Radical and Khosla co-leading, Dean gains capital and independence while his former employer hedges on his bet that AI-driven science is the next frontier beyond answering questions.
