How do real founders ship an MVP with AI in days instead of months?

The pattern is consistent: scope one core workflow, prompt a working prototype in hours, put it in front of 5-10 real users within days, and iterate on live feedback instead of specs. Pieter Levels built a flight simulator in 3 hours that hit $1M ARR in 17 days, and Karpathy shipped a paid app (MenuGen) without reading the code. The winners treat the MVP as a test of demand, not a finished product, and expect the messy 30% (auth, payments, polish) to take longer than the demo.
