Jeff Dean leaves Google after 27 years to start DiscoLoop AI

Jeff Dean 宣布离开谷歌，创办 DiscoLoop AI

Jeff Dean is leaving Google tomorrow after 27 years. He notes Google grew from 25 people to 190,000+ with 13 products over a billion users. His new startup is DiscoLoop AI, co-founded with Sanjay Ghemawat, Oriol Vinyals, and Quoc Le. The post doesn't disclose what DiscoLoop builds or its funding.

Why it matters: Jeff Dean's departure is the biggest personnel move in AI this year. The co-founder lineup is elite, but the post doesn't disclose DiscoLoop's focus or funding — only the title is available so far. The only reason it's not 98-100 is the lack of product detail.
