Got an idea? Building an app? Bring it to the mic. Kick off the first day of the Expo by pitching to someone who's heard thousands of them, and knows what makes one stick. Idea Hour is a live, open mic pitch session right in the middle of the Expo floor. Walk up, pitch what you're working on, and get real-time feedback from Arlan Hamilton, founder of Backstage Capital and one of the most vocal champions of underrepresented founders in tech.
