When YouTube kicked Pat Walls’ Starter Story channel off the platform, he spent a weekend getting Claude Code to build him a replacement. I wanted to see how it was done, so he walked me through it step-by-step.
Turns out it was a mistake and he’s back on YouTube, but the site he made was so good that it’s his company’s new homebase.

Starter Story generates over $2M a year through subscriptions, courses, and content, and its YouTube channel reaches millions of viewers each month.
