He Ignored Every Startup Rule and Built a $2.5B AI Company
Biography
Stable Diffusion as Modal's inflection
Erik describes how Stable Diffusion's release drove explosive inbound demand and validated Modal's positioning for ML workloads.
In this episode, Wouter sits down with Erik Bernhardsson, founder and CEO of Modal, the cloud compute platform that powers some of the fastest-growing AI companies in the world, including Lovable, Meta, and Chai.
Before Modal, Erik built Spotify's recommendation engine from scratch; then scaled Bolt's engineering team from 10 to 10,000 people in five years; and watched it nearly collapse when interest rates rose.
He started Modal self-funded, with a tiny team and almost no customers, two years before anyone noticed. Then stable diffusion dropped, and everything changed overnight.
Erik talks about why you learn more from success than failure, how he keeps a pulse on an 80-person organization, and the fundraising advice he gives every founder: raise less than you think, at a lower valuation than you want, and never confuse VC enthusiasm for a strategy.
If you're building something hard and wondering whether conviction is enough to carry you through, Erik is proof that sometimes it is.
