A simple build plan
- Week 1: Build the core. Pick one user problem and get the main flow working.
- Week 2: Test with people. Watch someone use it. Fix what gets in their way.
- Week 3: Refine the product. Improve the demo and collect evidence of what users find useful.
- Week 4: Prepare your submission. Record your pitch and demo, check access to every link, and submit early.
What to show the judges
Explain who needs your product, what you learned from them, and why your team can build it. Show the product working and how it could become a business.
Before you submit
- Add every team member to the Colosseum project.
- Prepare a clear pitch and a separate technical demo. Check the current format and time limits in Arena.
- Make the app, videos, deck, and repository accessible to reviewers.
- Disclose work completed before the hackathon and identify what you built during it.
