Top AI staff leave for new labs

Top researchers from Google DeepMind, Meta and OpenAI are leaving big labs to start their own AI companies, and investors are funding them at extraordinary speed. (cnbc.com) CNBC reported Tuesday, April 28, that months-old startups founded by former frontier-lab staff are already raising hundreds of millions of dollars. The article names former employees from OpenAI, DeepMind, Anthropic and xAI among the founders pulling in fresh capital. (cnbc.com) The clearest example came a day earlier: David Silver, the former head of reinforcement learning at Google DeepMind, said Ineffable Intelligence raised a $1.1 billion seed round. The London startup was founded in late 2025 and emerged with a $5.1 billion valuation. (cnbc.com) That round was co-led by Sequoia Capital and Lightspeed, with backing from Nvidia, Google, DST Global, Index Ventures and the United Kingdom’s Sovereign AI Fund. CNBC said the company is pursuing “superintelligence” and building around reinforcement learning, where systems learn from experience instead of only from human-written text. (cnbc.com) Another closely watched new lab is Recursive Superintelligence, founded by former Google DeepMind engineer Tim Rocktäschel. CNBC said the startup was reported last week to be raising up to $1 billion. (cnbc.com 1) (cnbc.com 2) A separate report cited by multiple outlets said Recursive had already raised at least $500 million at a $4 billion pre-money valuation, led by GV with Nvidia participating, and that the round could grow. The founding team includes Richard Socher, Tim Rocktäschel, Josh Tobin, Jeff Clune and Tim Shi. (the-decoder.com) (techfundingnews.com) Meta is part of the same pattern from the other direction. CNBC said AMI Labs announced a $1 billion raise in March, months after founder Yann LeCun said he was leaving his role as Meta’s AI chief. (cnbc.com) TechCrunch reported March 9 that AMI Labs actually raised $1.03 billion at a $3.5 billion pre-money valuation. The company says it is working on “world models,” systems trained on reality from sensors and video rather than mostly on language from the internet. (techcrunch.com) OpenAI alumni are in the mix too. CNBC listed Periodic Labs and Humans& among the ventures started by former staff from OpenAI, DeepMind, Anthropic and xAI that have raised hundreds of millions. (cnbc.com) TechCrunch reported in October that Periodic Labs was founded by former OpenAI research leader Liam Fedus and former Google Brain researcher Ekin Dogus Cubuk, and launched with a $300 million seed round. The company is trying to use AI, robotics and lab equipment to speed up materials science experiments. (techcrunch.com) The money behind these spinouts is rising fast. CNBC cited Dealroom data showing venture firms put $18.8 billion into AI startups founded since the start of 2025, putting 2026 on pace to exceed the $27.9 billion raised last year by startups founded since the start of 2024. (cnbc.com) Investors told CNBC that the opening comes from the priorities inside the largest labs. Eurazeo managing director Elise Stern said areas like new architectures, agents, interpretability and vertical models can get deprioritized when the biggest companies narrow focus around the immediate race. (cnbc.com) That helps explain why the talent flight is being watched so closely: the people leaving are not just starting companies, they are taking specific research agendas with them. The next wave of AI products may come from labs that did not exist a year ago. (cnbc.com)
