Ship an MVP. Learn whether people care.

A focused competition for builders with a testable product hypothesis and testers who can produce useful evidence about what works.

Testers compete on usefulness

Complete missions and earn points when reports are accepted as actionable.

Credentials cite evidence

Every earned credential links to the project, usage, reports, score, and issuer status.

Builder rules

  • Submit one original app or agent with a clear product hypothesis.
  • Provide a working public demo, repository or verifiable build evidence, and a short product walkthrough.
  • Define one test mission that a new user can complete in 10 minutes or less.
  • Respond to tester reports and document which feedback changed the product.
  • Do not buy, automate, duplicate, or self-generate usage and feedback.

Tester rules

  • Complete the app's defined mission before submitting a report.
  • Include reproduction steps for bugs and concrete context for product feedback.
  • One useful report per app earns full mission credit; duplicate or low-effort reports do not.
  • Disclose conflicts when testing your own team, employer, or close collaborator.
  • Public leaderboard participation is optional and aliases are allowed.
