Launch Your Product in 24 Hours (From Nothing)
One day. One promise. One live product.
A single-day sprint from blank editor to a product strangers can use and pay attention to. No committee, no roadmap, no six-week discovery phase — just the sequence of decisions that turns an idea into something live before the day is out, on infrastructure you own from hour zero.
Begin the courseWhat you leave with
- Pick an idea you can actually finish in a day — and reject the ones you can't
- Cut a fuzzy idea down to a single promise a stranger understands in ten seconds
- Own everything from hour zero — the code, the infrastructure, the database, the domain
- Drive Claude Code deliberately, splitting Opus and Sonnet so a full day of agent work stays affordable
- Build the working spine of a product before touching a single nice-to-have
- Make something built in hours look like something built over months
- Put it in front of the first ten people and read what they do, not what they say
