Last Friday, Europe's tech ecosystem buzzed with news that AI pioneer Yann LeCun was launching an AI-focused venture capital firm called Extelligence Invest. Within hours, however, the Meta chief AI scientist abruptly departed the fund. On the latest Sifted podcast, reporter Maya Dharampal-Hornby joins host Freya Pratty to dissect the curious episode.

They discuss Extelligence's planned investment focus, the team behind it, and potential reasons for LeCun's swift exit. Despite the brief venture, LeCun remains deeply active in AI entrepreneurship. Earlier this year, his Paris-based world models startup AMI Labs secured $1bn in funding, doubling its initial $500m target.

He also serves as an advisor to Hiro Capital, a VC firm operating across London and Luxembourg. The episode highlights the fluid dynamics between AI research leadership and commercial venture building in Europe's evolving tech landscape.
