I didn't even make it to the first round but the ones that got selected and won don't make any usable sense at all. They won and the 'business/app' dies at that Hackathon. There were no practical application at all.
New technology applied to an existing market or a new product aimed at an existing market is a lot safer of a bet if you're trying to build a business.
Looking forward to try your app!
Judges came around to review and score everyone (every team had multiple judges stop by), and a shortlist of hacks made it to the final round where it was more of a traditional pitch-off, with different judges.
If they do this again, they should shorten the expo significantly and do it in stages, so that nobody has to stand and talk for two hours.
Expo definitely favors larger teams as we only allow one person to demo from each team at a time, leaving the team members to swap out and check out all the other hacks. While the demos in front of everyone may be more fair, the expo builds community and gives people the opportunity to get immediate feedback on their pitch/product even if they dont win a prize or make it to the final round.
You should've seen the energy in the room.
The hackathon explosion is just getting started, I'm sure things will continue to improve as these events mature.
