Yann LeCun confirms his new ‘world model’ startup, reportedly seeks $5B+ valuation

Yann LeCun, a prominent figure in artificial intelligence, has officially announced the formation of his new startup, Advanced Machine Intelligence (AMI). Although widely anticipated, the revelation comes with a twist: LeCun will not take the reins as CEO. Instead, the leadership mantle will be passed to Alex LeBrun, previously the co-founder and CEO of the medical transcription AI company, Nabla. In a post on LinkedIn, LeCun confirmed his role as Executive Chairman, stating, "Yes, AMI Labs is my new startup. I’m the Executive Chairman. And Alex LeBrun is transitioning from CEO of Nabla to CEO of AMI Labs!" AMI Labs is reportedly aiming to raise €500 million (approximately $586 million) at a staggering €3 billion valuation (about $3.5 billion) even before launching its operations, as reported by the Financial Times. Given the current investment climate where venture capitalists are directing large sums towards AI startups led by recognized experts, this valuation may not seem far-fetched. For context, the startup Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, was valued at $12 billion during its seed funding round last year. LeCun, who serves as a professor at New York University and was formerly the VP and Chief AI Scientist at Meta, is celebrated for his groundbreaking contributions to reinforcement learning, having received the prestigious A.M. Turing Award. His new venture, AMI Labs, is focused on developing world model AI, an innovative approach that seeks to comprehend environments to simulate cause-and-effect and predict outcomes—an alternative to traditional large language models (LLMs). The ambition for AMI Labs' fundraising could be viewed as bold, especially when compared to similar startups. For instance, Fei-Fei Li's World Labs raised $230 million at a $1 billion valuation during its early stages back in August 2024. Meanwhile, Nabla, which is currently in search of a new CEO, will continue operations under the leadership of co-founder and COO Delphine Groll. LeBrun's departure from Nabla has been announced alongside the news of his new role, where he expressed confidence in the company's growth trajectory, stating, "We have more than tripled our live ARR this year. Up next to $1B!" Despite his transition to AMI Labs, LeBrun will retain a position at Nabla as chairman and Chief AI Scientist. The startup has successfully raised a total of $120 million from esteemed investors, including Tony Fadell’s Build Collective and HV Capital. As AMI Labs embarks on this exciting journey, the AI community will be watching closely, especially given the potential implications of its world model approach on the future of AI technology.
