Pieter is a bootstrap software company builder, indie hacking, GOAT. He's built several multimillion dollar software businesses without funding after teaching himself to code. His software stack is incredibly naive, single-file pgp apps written without frameworks and backed by an embedded sqlite database, demonstrating that software value is independent of sophisticated engineering.
Whether you aspire to raise money or not, there's a lot ~builders can learn from Pieter. Notably: failing fast, doing things that don't scale, and charging money early to prove you're providing value.
