If you haven’t been to one before, here is the general jist of it. A few people give 10-15 minute long demos, typically of a startup they are working on. This is the main dish. Then several more people talk briefly (1-5 minutes) on their startup. All have booths setup on the perimeter of the area for you to check out. From there, it’s networking, schmoozing, and what have you. It’s a good sized crowd, with several hundred at the last meeting.
