Yann LeCun Launches New ‘World Model’ Startup Aiming for Over $5 Billion Valuation
Renowned in the tech community, AI visionary Yann LeCun recently unveiled his latest venture, capturing the attention of industry insiders and enthusiasts alike. With the unveiling of his startup, Advanced Machine Intelligence (AMI), the excitement is palpable. Notably, LeCun will assume the role of Executive Chairman, while the talented Alex LeBrun, formerly CEO of Nabla, steps in to lead AMI as its new CEO.
The Launch of AMI Labs
In a post on LinkedIn, LeCun confirmed, “Yes, AMI Labs is my new startup. Alex LeBrun is transitioning from CEO of Nabla to CEO of AMI Labs!” This strategic leadership shift hints at a promising direction for the company, which is already strikingly ambitious, targeting a valuation of €3 billion (approximately $3.5 billion) while seeking to raise €500 million (~$586 million) even before launching.
The Competitive Landscape
The tech space is currently teeming with investment opportunities in AI, especially those spearheaded by globally recognized experts. Former OpenAI CTO, Mira Murati, saw her startup, Thinking Machines Lab, valued at an astonishing $12 billion in its seed round last year, setting a high bar for newcomers.
LeCun, a celebrated professor at New York University and former Chief AI Scientist at Meta, boasts an impressive resume, having received the esteemed A.M. Turing Award for his contributions to reinforcement learning.
World Model AI: A New Frontier
AMI Labs is poised to explore groundbreaking developments in world model AI, presenting a transformative alternative to traditional large language models (LLMs). Unlike LLMs, which can be prone to generating inaccurate information due to their non-deterministic nature, world models aim to simulate environmental understanding, allowing for more reliable predictions grounded in cause-and-effect reasoning.
Leading tech labs like Google DeepMind and Fei-Fei Li’s World Labs are also diving into this domain, intensifying competition in the AI landscape. Notably, Fei-Fei Li’s startup raised $230 million at a $1 billion valuation; however, that was deemed a significant achievement back in August 2024.
Leadership Transition at Nabla
Following LeBrun’s departure, Nabla has announced a quest for a new CEO, with co-founder Delphine Groll currently steering the ship. This transition comes alongside a strategic partnership that will see Nabla utilize AMI’s innovative models as they become available.
Nabla boasts a remarkable funding track record, accumulating $120 million with a recent $70 million Series C round. Notable backers include Tony Fadell’s Build Collective and HV Capital.
The Expertise of Alex LeBrun
LeBrun brings a wealth of experience to his new position at AMI Labs. He has been instrumental in building multimodal AI systems even before they gained popularity, having worked at Nuance Communications in the early 2010s—an early technology provider for Apple’s Siri. Following his successful entrepreneurship in natural language startups and his tenure leading Facebook’s AI division, LeBrun seems well-equipped to guide AMI’s ambitious objectives.
In his announcement regarding his transition, LeBrun expressed optimism about Nabla’s growth trajectory, boasting that they have tripled their live ARR this year, edging close to the $1 billion mark. He plans to remain engaged with Nabla, taking on the role of chairman and chief AI scientist.
As we witness the rise of AMI Labs, it’s clear that the excitement in the AI landscape is only just beginning.
