I think it's possible that they could fund an innovative, perhaps decentralized, somewhat crowdfunded, YC-like DAO (decentralized autonomous organization).
Why do startups in general apply to YC? For expert mentorin from people who have done it 700 times before, for a fantastic Rolodex and a badge that will at least get you a coffee from most VCs and CTOs.<p>If you were just copying YC, I doubt they would add much value. If you were doing YC-for-a-niche then maybe. I suspect YC for Africa would get some interest, YC-for-biotech maybe less.
