Summary
Google veteran Jeff Dean formally exited the company last week and became a Discovery Loop cofounder one minute after midnight, ending a 30-year run that took him to chief scientist.
139 close colleagues learned of the move in a Wednesday video call before Dean announced the startup at 9 a.m., saying only about 12 people had known in advance.
1,500 coworkers packed a café built for 300 at his farewell event, underscoring Dean's reach after leading roughly 4,400 people across Google's research and AI teams.
400 internal messages kept Dean replying until 2:30 a.m., and 250 more arrived the next morning alongside 500 emails before he closed his laptop for the last time.
At KDD in South Korea, Dean shared the blow-by-blow of his final two days, framing the departure as a personal leap into building a new AI company with former colleagues.
