Why Lightspeed backs big bets like xAI

Michael Mignano, Partner at $30B VC firm Lightspeed, and the co-founder of Anchor, a podcast creation, hosting, and monetization platform acquired by Spotify in 2019, joins Sourcery to discuss the next era of creation & technology investing.

In this episode, Michael shares how his background building consumer media products informs the way he invests today, with a focus on AI and creativity-driven companies. We discuss his portfolio, including investments in xAI, Neuralink, Suno, Pika, Granola, and Macroscope, and how he evaluates AI businesses when incumbents can move quickly.

The conversation digs into what makes AI companies defensible today, from retention-driven moats to why ARR metrics can be misleading. Michael shares his reaction to the Sora launch and avatars, and what these changes could mean for creators. 

We also touch on evolving early-stage check sizes, lessons from Spotify’s Daniel Ek, his work on Obo, and thoughts on potential IPO candidates.
