Jeff Dean Left Google With Three Co-Founders, Not One

Jeff Dean announced on X that August 6th would be his last day at Google after 27 years, and named three co-founders in the same post: Sanjay Ghemawat, Oriol Vinyals, and Quoc Le. Their new venture, Discovery Loop, is incorporated as a public benefit corporation and is aimed at automating large-scale experimentation — starting with machine learning research and engineering, with a stated ambition to extend the approach across science. We cover what's confirmed (the departure, the date, the co-founders, the mission), what isn't (the size of the round, the reported Google DeepMind leadership reshuffle described by Latent Space), and the practical read: watch Google's release cadence over the coming quarters, and watch whether the exits stop at four.
