DayOne combines two things no other builder has together:
1. 150 validated startup ideas — each with real market research, TAM, competitor analysis, and a full business plan
2. An AI builder that generates a full multi-page React app in ~2 minutes from a single sentence
Pick an idea, build the app, publish to a live URL. Free during beta.
Built solo by a 19 year old from Dallas, studying abroad in Florence Italy.
