Ineffable Intelligence, the London based AI startup founded earlier this year by former Google DeepMind researcher David Silver, has added six new cofounders pulled largely from DeepMind and the AI firm InstaDeep, according to Fortune. The company is built around reinforcement learning, a training approach where AI models learn through trial and error to maximize a defined reward, with the stated goal of eventually building AI superintelligence.
Four of the new cofounders come directly from Google DeepMind. Chris Apps, a former technical program and research delivery lead who managed large researcher teams, will lead what the company calls mission acceleration. Wojciech Czarnecki, who specialized in multi agent AI research and worked on AlphaStar, will oversee Ineffable's science team. Lasse Espeholt, who helped build Google's MetNet weather prediction models, is taking charge of compute, infrastructure, and engineering strategy. Junhyuk Oh, who led reinforcement learning work on AlphaStar and was an early pioneer of using AI to discover new reinforcement learning algorithms, will run the company's reinforcement learning operations.
A fifth cofounder, Alexandre Laterre, joins from InstaDeep, the London based AI firm BioNTech acquired in 2023, where he served as head of research. He will oversee research engineering at Ineffable. The sixth, Heather Gorham, previously a partner at venture firm Flying Fish, is the one who first approached Silver about reinforcement learning back in early 2024. She is now managing compute, fundraising, and operations, and was instrumental in securing Ineffable's Google Cloud partnership.
