01 Everyone gets a mic<br>You are matched into at least two networking groups of 70 to 100 people. In each one you get 60 seconds on the mic to say who you are and what you are building.
02 Teams of 5+ get a longer slot<br>Bring five or more from your company and you get extended time, and slides, to introduce the team to the room.
03 Founders' round with Garry Tan<br>A dedicated group for founders and founding teams with the President and CEO of Y Combinator.
