Slides are optional. But, you're limited to 7 minutes to present, no exceptions.
Any slides need to be submitted to the organizer at minimum two hours prior to the event start. We take PDF or Keynote. PPT can be opened but we don't own Powerpoint so they'll likely look bad.
If you need one, a reasonable format is seven slides:
1) Who Is Your Customer
2) What Problem You're Solving
3) Your Solution
4) How You Will Make Money
5) Progress to Date (revenue, prototype, etc)
6) Team Overview (who you are and why you're the right people to do this)
7) Ask (funding, manpower, partnerships)
But, you can use your own if you'd like.
