OUR INTERN BUILT THE FIRST ZERO-PERSON BUSINESS

Summary from the TLDR Marketing newsletter

An AI agent built and launched an app by running a tight loop of user interviews, concept testing, building, and iteration. It used Listen Labs to run 2,000 interviews and test 100 ideas in parallel with subagents. Image models handled product builds, while Meta ads drove acquisition. The agent landed on StyleFits, an AI stylist shaped by real user feedback. It pivoted based on low NPS, pricing friction, and trust gaps, then added free trials and shopping links. The result was a scrappy product with hundreds of paying users.
