What would be the benefit to foundations of doing a similar deal? Seems that they mostly have passed on YC-funded nonprofits including Immunity Project and Zidisha; and for good reasons. It seems that YC is a little behind when it comes to nonprofits - funding things that were very popular years ago like crowdfunding (Kiva comes to mind). These things are still exciting but they aren't at the edge of nonprofit innovation today. Organizations like Sanergy or GiveDirectly are really disrupting the nonprofit industry. Would love to see YC make a bet like one of those.
