Discovery Loop, an AI startup co-founded by former Google chief scientist Jeff Dean on August 5, 2026, is negotiating a new funding round at a valuation of about $50 billion. That figure is five times the roughly $10 billion valuation target discussed several weeks earlier, highlighting the premium investors are placing on scarce AI talent. The company has not publicly disclosed products, customers or revenue, instead focusing on AI systems that can autonomously run and refine thousands of scientific experiments in parallel. Dean’s co-founders are Sanjay Ghemawat, Quoc Le and Oriol Vinyals. Radical Ventures and Khosla Ventures led the initial funding round, with Lightspeed, Kleiner Perkins and Doerr Capital among the participating firms.
