# Who’s Behind AMI Labs, Yann LeCun’s ‘World Model’ Startup
In the rapidly evolving AI landscape, AMI Labs has emerged as a bold new player, founded by Meta’s former chief AI scientist **Yann LeCun**. As of early 2026, the startup—short for Advanced Machine Intelligence—is laser-focused on developing **world models**, AI systems designed to understand the physical world, reason, plan, and interact safely, moving beyond the limitations of large language models (LLMs).[2][3][5]
## LeCun’s Vision: A Contrarian Bet on Real-World AI
Yann LeCun, a **Turing Prize winner** and pioneer of convolutional neural networks, left Meta after leading its FAIR lab to launch AMI Labs. He serves as **executive chairman**, not CEO, emphasizing continuity from his prior research on advanced machine intelligence.[2][3][5] LeCun has long criticized LLMs for issues like hallucinations and their text-prediction focus, arguing they can’t achieve human-level AI without grasping physics, causality, and persistent memory.[2][3]
AMI’s mission, as stated on its website, is to “build intelligent systems that understand the real world.” This positions it against rivals like **World Labs**, founded by Fei-Fei Li, which recently launched Marble—a tool for generating physically accurate 3D worlds—and is eyeing a $5 billion valuation.[2][4] AMI promises controllable, safe AI for high-stakes fields: healthcare, robotics, industrial automation, wearables, and more. Unlike generative models weak on sensor data, AMI’s tech will feature reasoning, planning, and reliability.[2]
LeCun plans to license tech to partners, contribute open-source code, and publish academically while retaining his NYU professorship in New York.[2] Meta could be AMI’s first client, though LeCun has critiqued Zuckerberg’s strategies.[2]
## Leadership: Alex LeBrun Takes the CEO Helm
At the helm is **Alexandre (Alex) LeBrun** as CEO, a serial AI entrepreneur poached from Nabla, a health AI startup he co-founded with Paris and New York offices.[2][3][4][5] LeBrun’s move stems from a December 2025 Nabla partnership: Nabla gains “privileged access” to AMI’s models, while LeBrun shifts from Nabla CEO to chief AI scientist and chairman, freeing him for AMI.[2]
LeBrun’s pedigree includes selling Wit.ai to Facebook, where he worked under LeCun at FAIR.[2] He’s drawn to AMI for healthcare applications, where LLM flaws like hallucinations are critical.[2] Reports suggest **Laurent Solly**, ex-Meta VP for Europe, may join, hinting at Meta talent overlap.[2] Unconfirmed rumors mention **Xie Saining** as potential chief scientist.[6]
## Global Footprint and French Ambitions
AMI Labs is **headquartered in Paris**, a nod to LeCun’s French roots—AMI evokes “ami” (friend).[2][3][5][6] French President Emmanuel Macron hailed it, pledging support to boost Paris as an AI hub alongside Mistral AI and H.[2] Offices are planned in New York, Montreal, and Singapore, making it a global operation.[2][6]
This Paris base aligns with LeCun’s vision for a “global company.”[2]
## Funding Buzz: $3.5 Billion Valuation Talks
Pre-product, AMI is in funding talks at a **$3.5 billion valuation** (or ~3 billion euros), per Bloomberg and others—rivaling World Labs’ trajectory.[3][4][6] Potential investors include Cathay Innovation, Greycroft, Hiro Capital (LeCun advisor), 20VC, Bpifrance, Daphni, and HV Capital.[4] TechCrunch notes related buzz around Inferact’s $150M vLLM raise, signaling inference hype.[1]
Notably, backers like **Alex Pall and Drew Taggart** (The Chainsmokers) via MANTIS VC, and **Assaf Rappaport** (Wiz co-founder/CEO) are linked, though details are emerging.[2]
## Why World Models Matter Now
World models represent AI’s next frontier: systems that simulate reality for better robotics, autonomous systems, and safety-critical apps.[2][4] LeCun’s departure from Meta underscores his push for this shift, potentially revolutionizing industries where LLMs fall short.[3]
As AMI Labs ramps up, it embodies LeCun’s mantra: “Real intelligence does not start in language. It starts in the world.”[2] With elite talent, strategic partnerships, and investor interest, watch this space—details may solidify by February 2026.[6]
