What is a Build Sprint?
A hackathon for the way developers work now
A developer no longer mostly types code. A developer owns a product and steers AI agents that build it. A Build Sprint practises exactly that.
You, or a small team
Work alone or with up to three people. Plus AI agents that do the building.A real brief
A clear problem to solve, with rules and a list of what to hand in.Judged on the Product Package
Not on how much code you typed. On how well you own the whole product.
How it works
Four steps from brief to submission
Pick an open brief
Read the brief in full: the goal, who it is for, the rules, and what to hand in.
Plan it yourself
Write the epics and the roadmap in your own words. People write epics; AI never does.
Steer the agents
Break the work into small issues. Let AI agents draft the changes. Read every change before you accept it.
Package and submit
Put your Product Package in a public repository and send us the link. Each brief explains exactly how.
Judging uses the six skills of the Product Package rubric. Rewards are being finalised; we will not promise any prize before it is real.
