I run free one-week AI sprints for small businesses in Japan: consult → build → collect real feedback → improve → ≥95% satisfaction in a survey. Ten businesses is the first target — once it's done, I raise the bar. Each finished sprint gets its own page with the full story and a demo you can play with. The challenge lives at tubaali.github.io/ai-sprint.
Each lantern is one business. A lit one opens its story.

The process is the guarantee
Every sprint runs the same loop, and it only exits at ≥95% satisfaction — otherwise it goes around again.
The five stories so far — every one playable
An izakaya, an Airbnb owner, my own research team, a property manager, a venture fund. Different pains, one loop — and twice, the honest answer had almost no AI in it.
