Jeff Dean departs Google after 27 years to launch new AI startup Discovery Loop

Jeff Dean is leaving Google after a 27-year tenure to launch a new public benefit corporation called Discovery Loop. The startup, co-founded with Google senior fellow Sanjay Ghemawat, aims to use high-octane algorithms to automate and accelerate scientific research and engineering. The administration announced that Google will serve as a founding investor and cloud partner for the new venture, which seeks to move beyond simple question-answering to make complex discoveries through recursive self-improvement. Simultaneously, Google is restructuring its AI leadership. Demis Hassabis will transition from his day-to-day role as CEO of Google DeepMind to become the Chair of Google DeepMind and Chief Scientist of Alphabet. Koray Kavukcuoglu will succeed Hassabis as the senior vice president of Google DeepMind, overseeing the development of the Gemini 4 model. These changes come as Google navigates a competitive AI landscape, balancing heavy capital expenditures on infrastructure with a booming cloud business that saw an 82% revenue increase in the second quarter.
