My answer to What is the biggest team to join Y Combinator? on Quora
Larger teams that apply for YC generally have to nominate 2-3 “founders”, mainly for logistical reasons: there simply isn’t enough room at the dinners for larger groups. The non-founders don’t get to go to all of the dinners, though they can come along to a few of them as guests of the founders.
