Google's Top AI Researchers Leave to Launch Discovery Loop: Automating the Scientific Method

On August 5, 2026, four of Google's most senior AI researchers left the company to launch Discovery Loop, a public benefit corporation with a mission to automate the experimental loop of scientific and engineering research. The startup aims to build AI systems that can propose hypotheses, design and run experiments, evaluate results, and iterate — at massive scale, with minimal human intervention.

The Founders: A Combined Century of Experience

Discovery Loop is co-founded by four researchers who collectively accumulated well over a century of experience at Google :

• Jeff Dean — Google's chief scientist, co-founder of Google Brain, and employee #30 at Google. He serves as Discovery Loop's CEO .
• Sanjay Ghemawat — Google Senior Fellow and co-creator of MapReduce, Bigtable, Spanner, and the Google File System .
• Oriol Vinyals — VP of Research at Google DeepMind, known for foundational contributions to deep learning and reinforcement learning .
• Quoc Le — Founding member of Google Brain and a leading figure in deep learning research .

Mission: Automating the Scientific Method

Discovery Loop describes its goal as building AI systems capable of recursive self-improvement — AI that can improve itself with little or no help from humans . The company's pitch, in Dean's own words, is that the scientific method itself (propose a hypothesis, run the experiment, evaluate the result) is a loop, and loops are exactly the kind of thing you can automate .

"Imagine a future where a handful of people can do what previously required thousands of scientists and engineers" — Jeff Dean .

The company plans to start by focusing on machine learning research and engineering, then expand into hardware design, drug discovery, and clean energy .

Funding and Investors

Discovery Loop's seed round was co-led by Radical Ventures and Khosla Ventures, with participation from Lightspeed Venture Partners, Kleiner Perkins, and Doerr Capital . In a rare move, Alphabet (Google's parent company) joined as a founding investor and also agreed to supply cloud computing power for at least the first year . The round amount and valuation have not been publicly disclosed .

As of mid-August 2026, Dean has reportedly been in discussions to raise a $1 billion round at an approximate $10 billion valuation, though terms remain subject to change .

Corporate Structure

Discovery Loop is incorporated as a Delaware public benefit corporation, which legally commits the company to a public-benefit purpose alongside shareholder value . Wilson Sonsini is advising the company on legal matters .
