Discovery Loop, an AI startup co-founded by former Google Chief Scientist Jeff Dean, is in talks for a new financing round that would value the company at $50 billion. The target marks a fivefold jump from its roughly $10 billion valuation goal just weeks ago. The company was co-founded by Jeff Dean, Sanjay Ghemawat, Quoc Le, and Oriol Vinyals. Discovery Loop aims to use AI to run thousands of experiments in parallel to accelerate scientific and engineering research. Its initial funding round was led by Radical Ventures and Khosla Ventures, with participation from Lightspeed, Kleiner Perkins, and Doerr Capital.
