  2. Your software must include real time features built using Rapid
  3. The teams optimally consist of one to four people, some combination of developers and UX/designers.
  4. Judging consists of the panel of judges and mentors listed above, hearing the pitch from the team leader, asking questions and taking notes.
  5. Will award 1st, 2nd, and 3rd place, as well as a bunch of prizes from our partners.
  6. There will be food the entire time.
  7. You can go home and come back.
  8. You cannot bring guests--sorry!
  9. There will be no press.
  10. We may, at our discretion, audit the code of the projects to ensure their work was done during the Hackathon. Teams may use open source code and public APIs, but we ask that teams not write any code or do any designs before the Hackathon starts (Wireframes and UX are OK).
