Thinking about finding a co-founder through YC’s matching service? This guide answers one question on each page, so you can go straight to the one that affects your next step.

Each page keeps to one topic and gives its numbers with dates. The main rules come from the Startup School FAQ and YC’s matching page. The independent public record is small: two Trustpilot reviews and three Hacker News items, one of them a founder’s tally of profiles. [1] [2] [3] [4]
