Steve Ruiz was about to start at Adobe. Bags packed. Job accepted. Start date: Monday.

Then he looked at what was happening with his side project — an open-source canvas tool he'd been building — and 200,000 people were using it every month. Hundreds of sponsors had put up 00,000. Two major companies wanted to build on it. He called Adobe and said he wasn't coming.

That project became TLDraw.

Steve's background isn't in software — it's in fine art. He has a masters in it. He spent thousands of hours studying ink on paper — how it moves, how it bleeds, how it dries. And when he later wrote the algorithms for digital ink, he had this deep physical knowledge that most engineers just don't have.

We talk about why he killed his own SaaS product to focus on the SDK, why he thinks craft only matters when you're building for high-agency users, and his surprisingly simple answer to the question every open-source founder faces — how do you actually make money?
