In this video, I walk through the five-prompt build process, the agent testing loops, and the manual UX fixes AI still missed. I also break down the real numbers behind the project. How long it took, how many agents it used, and how much it cost me.

Makers residency 4th edition

Your idea can be anything. At our last workshops, people built plant-based nutrition businesses, a way to measure planetary resilience, crochet headwear and a way to connect lonely people living in the same building. An asset manager went on to raise an additional £25M on their fund within nine months. The fourth workshop is a full day at KOKO with Nick Sarafa, learning to build with Claude Code. Bring the thing you keep meaning to start. We’ll bring the pizza.
