I will be surprised if YC even has any pain points that are well enough understood to be concisely communicated to an external source and can be solved in 72 hours. Usually the reason you have a pain point is either that you don't understand the underlying problem yet, or the solving it will take time. But I suppose that just means any pain points YC may be able to convey are things where these guys are expected to fail, which I guess is the whole spirit of the challenge.
