Jeff Dean, one of Google’s longest-serving and most influential AI leaders, is leaving the company to start a new artificial intelligence venture. He is reportedly being joined by other departing Google executives and researchers as co-founders.

The move is notable because Dean has been closely associated with Google’s AI efforts for years. His exit signals a major shift for one of the company’s best-known technical figures and highlights how experienced researchers are increasingly choosing to build independent AI companies.

According to the report, the new startup will focus on using AI to help advance scientific discovery. That suggests the company aims to apply machine learning beyond consumer products and software tools, targeting research workflows and the broader process of finding new insights in science.

With several former Google leaders involved, the startup is likely to draw attention across the tech and research worlds. It also reflects a wider trend in which top AI talent is moving from large platforms into new ventures built around specialized, high-impact uses of artificial intelligence.
