Hassabis Exits DeepMind CEO Role in Google AI Shakeup
3 min readDemis Hassabis is giving up day to day control of Google DeepMind. The Nobel laureate who built the lab into Alphabet’s AI engine becomes chairman of the unit and takes a new role as Alphabet’s chief scientist, and he is stepping back alongside one of the largest waves of senior departures Google research has ever seen. Alphabet shares fell more than 4 percent on the news.
How DeepMind Got Here
Hassabis co-founded DeepMind in 2010 and led it through the Google acquisition, the AlphaGo and AlphaFold breakthroughs, and the 2023 merger with Google Brain that put all of Alphabet’s AI research under one roof. That combined unit has produced every Gemini model since, making its leadership one of the most consequential jobs in the industry.
It has also been under pressure. Google spent the past year working to close the gap with OpenAI and Anthropic on frontier models while absorbing a steady drip of researcher departures to rival labs and well funded startups.
What Happened
Koray Kavukcuoglu, previously DeepMind’s chief technology officer and Google’s chief AI architect, takes over daily leadership as a senior vice president reporting directly to Alphabet chief executive Sundar Pichai. Hassabis will continue to run Isomorphic Labs, the AI drug discovery spinout.
The reshuffle landed the same day as a cluster of high profile exits. Jeff Dean is leaving after 27 years as Google’s chief scientist, joined by senior fellow Sanjay Ghemawat, DeepMind vice president Oriol Vinyals, and Google Brain co-founder Quoc Le. The group is founding Discovery Loop, a public benefit corporation aimed at automating scientific and engineering discovery. Google is investing in the new venture and will serve as its cloud provider, which softens the break considerably.
Hassabis framed the move as freeing him to focus on the big picture of artificial general intelligence, which he described as close at hand. Pichai stressed the need to accelerate Gemini development and shape AGI responsibly.
Why It Matters
Losing a founder chief executive and a 27 year chief scientist in one afternoon is a serious signal, and the market read it that way. But the structure matters as much as the headline. Google kept Hassabis on the org chart, kept him pointed at AGI strategy, and bought a stake in the startup absorbing its departing talent rather than letting it walk to a competitor.
Watch whether Kavukcuoglu can raise Gemini’s shipping cadence, and whether Discovery Loop becomes a partner or a rival. Research leadership churn at this scale usually shows up in the product roadmap within a couple of quarters.
