Ship
or die.
A 30-day challenge for builders who want to push themselves to their limits. Build one app in public, from idea to the App Store, next to everyone in the cage below. Post your progress every day or you’re out.
Starts September 3 at 16:00 UTC
The cage is empty. Be the first one in.
How it works
Don't just copy another big app. Be original.
Working app by day 15. Build fast with AI.
Submit to App Store review.
UGC, organic, ads. Share your numbers with everyone.
One rule. Post your progress on X every day. Miss a day and you are out. Everyone who drops out stays forever on the losers page.
The upside. You build in public with an audience from day one. Hundreds of people watching your progress means real traffic to your app before it even launches.
The people. You spend 30 days building next to the same builders and seeing exactly how they work. You leave with an app and a network.
The prize. After day 30, everyone still standing goes on a leaderboard ranked by revenue. Winner gets the crown and a very good pinned tweet.
The cost. Free to join.
