Yann LeCun's venture capital fund, Extelligence, crumbles within hours.

      A brand-new venture capital firm appointed AI pioneer Yann LeCun as a partner on Friday morning, but by Friday evening, the fund had ceased to exist.

      LeCun has had a hectic year, but the past week has been particularly unusual. On Friday, a new venture firm called Extelligence Invest named him, often referred to as the “godfather of AI,” as a partner. Within approximately eight hours, their website was no longer active, LeCun had stepped away, and the firm had disbanded.

      Maya Dharampal-Hornby from Sifted first reported the story. She confirmed LeCun's involvement with his spokesperson prior to publication. Documents reviewed by the outlet indicated that Extelligence aimed to support early-stage startups in Asia, Europe, and North America. However, the entire situation unraveled publicly within hours.

      What Extelligence was intended to be

      On paper, Extelligence had a compelling proposal. The firm intended to invest in technical founders developing strong intellectual property across various sectors, including longevity, healthtech, new mobility, and computing. LeCun was listed as one of two “non-managing” general partners. The website even showcased 29 companies it purportedly backed, which a source informed Sifted were angel investments by the partners, meant to demonstrate a proven track record.

      For a brief period, it seemed like yet another venture for LeCun. He is the former chief AI scientist at Meta and an advisor to the European VC firm Hiro Capital. In March, he raised over $1 billion in seed funding for his own startup focused on world-models, AMI Labs, based in Paris. Establishing a VC firm would have aligned well with his trajectory.

      Eight hours later

      However, the situation disintegrated. Approximately six hours after the news broke, Extelligence informed Sifted that it had “recently learned” LeCun had “existing exclusive relationships with other funds that were not fully understood at the time,” citing legal and contractual issues. They expressed deep respect for him.

      LeCun’s spokesperson then stated that he had withdrawn from the firm, describing it as one of many ventures he was involved in. Roughly ten minutes later, Extelligence announced it would abandon the fund entirely. By Saturday, the website was back online, but devoid of any names.

      The unanswered questions

      The major mystery is how LeCun ended up publicly associated with a fund he seemingly couldn't join. Although he became an advisor to Hiro Capital last year, it hasn't been clarified if that was the source of the conflict. Neither party has elaborated on it.

      There were also peculiar details. Chris O’Brien, who contributes to the French Tech Journal, noted that Extelligence claimed it had registered with the US Securities and Exchange Commission and provided a link to the filing, but he could find no record of such registration. He also mentioned that the site appeared to be hastily constructed. No one has offered any explanations regarding these matters.

      A uniquely chaotic situation

      Regardless of what transpired, this incident reflects the current climate. Investors are eager to back anyone with a credible AI reputation, and many prominent figures find themselves juggling multiple roles across startups, funds, and advisory positions. LeCun himself has been one of the few skeptics, cautioning about the potential for an AI bubble despite continued investments leading to soaring valuations.

      Europe feels the pressure more intensely than other regions. The area is striving to develop its own embodied AI and deep tech leaders, and a fund associated with LeCun’s name would have attracted significant capital. For roughly eight hours, it had that potential, only to vanish shortly thereafter.
