Even then I think you are chasing the wrong horse. My wife has worked in non-profits and social good startups for several years now and getting to know her friends it's obvious that sometimes they may make decisions based around finances, but frequently and I would say usually their decisions are based around impact of the organization. YC stands the chance to greatly increase the organizational effectiveness of these organizations, which is an issue that many non-profits struggle with and could help them leap forward tremendously in their early days.
