AMI Labs, the Paris-based AI company founded by Yann LeCun, closed a $1.03 billion seed round in March 2026 at a $3.5 billion pre-money valuation, making it the largest prelaunch AI funding in European history, according to TechCrunch. The raise arrived four months after LeCun left Meta, where he had served as chief AI scientist since 2013.
The Exit from Meta
LeCun’s departure was confirmed on November 19, 2025, reported by CNBC. He had joined Facebook (later Meta) in 2013 to build what became Meta FAIR (Fundamental AI Research), one of the largest academic-style industrial AI labs in the world. His tenure covered foundational work on convolutional neural networks, open-source model releases through the Llama family, and the origination of the JEPA research program.
The split reflected a growing divergence over architectural bets. By late 2025, Meta had reorganised FAIR into the Meta Superintelligence Labs, completed a $15 billion acquisition of Scale AI, and oriented its product strategy firmly around generative models and Llama. LeCun’s public criticism of LLM limitations had sharpened in step. Speaking to The Decoder on his departure, he was direct: “You certainly don’t tell a researcher like me what to do.”
AMI Labs (Advanced Machine Intelligence) is headquartered in Paris. LeCun holds the title of executive chairman; he appointed Alexandre LeBrun, founder of French health-tech firm Nabla, as CEO. According to Fortune, Meta will not invest in AMI Labs, though the two organisations plan to maintain a research partnership allowing LeCun to continue JEPA-related collaboration with former FAIR colleagues.
A Record European Raise and Who Backed It
The $1.03 billion round was co-led by five institutional investors: Cathay Innovation, Greycroft, Hiro Capital, HV Capital, and Bezos Expeditions. Angel investors named in the TechCrunch disclosure include Tim Berners-Lee and Rosemary Berners-Lee, Jim Breyer, Mark Cuban, Mark Leslie, Xavier Niel, and Eric Schmidt.
