Eric Simons is the Co-founder and CEO of StackBlitz, best known for its breakout product Bolt, letting anyone build full stack apps from text, in the browser.

Bolt launched in October of 2024, quickly growing from zero to a $20 million revenue run rate in two months, making it one of the fastest growing products ever. But Eric will be the first to tell you it wasn’t an overnight success - the product didn’t even work the first time they tried building it.

We go behind the scenes of the seven year journey building the tech that eventually led to Bolt, how to avoid distractions, being capital efficient, living in a frat house for $100/month, and squatting in AOL’s headquarters for $1/day when he was 19.

Eric also takes us inside the weeks after Bolt’s viral launch, figuring out a new business model on the fly, his strategy for fundraising and PR, why you should open source your code, Bolt’s playbook for building a community around the product that enabled their viral launch, and how AI is changing software forever.
