Jeff Dean is leaving Google after 27 years to lead Discovery Loop, a Palo Alto public benefit company co-founded with Sanjay Ghemawat, Quoc Le, and Oriol Vinyals. Radical Ventures and Khosla Ventures are co-leading the seed round, with Alphabet as a founding investor and cloud partner; the amount was not disclosed. The plan is AI that proposes, runs, and iterates thousands of experiments in parallel, starting with machine learning research. Why it matters: Gemini era leaders are betting the next frontier is automating discovery itself. Caveat: there is no product yet, and recursive self-improvement claims remain speculative.
