The World's Premier College Hackathon

Show your love for hacking on Valentine's Day weekend at the University of Pennsylvania. 48 hours, $30,000 in prizes, and 1,200 of the best hackers from around the world. After the Friday evening kickoff, all teams are allowed to begin working on their apps. Once your app is complete, we ask that you make a submission to ChallengePost to let everyone (most importantly your judges) know about your hack. You can submit your app, and an accompanying video if you'd like to, using the Submissions tab above (which will appear after you hit the Register button). All submissions must be in by 9:30 AM Sunday morning.

Judging Criteria

  • Originality
    Is the hack more than just another generic social/mobile/local app? Does it do something entirely novel, or at least take a fresh approach to an old problem?
  • Technical Difficulty
    Is the hack technically interesting or difficult? Is it just some lipstick on an API, or were there real technical challenges to surmount?
  • Polish
    Is the hack usable in its current state? Is the user experience smooth? Does everything appear to work? Is it well designed?
  • Usefulness
    Is the hack practical? Is it something people would actually use? Does it fulfill a real need people have?
