Thanks Aaron! I've heard a little bit about Sparrow Giving and I think a key overlap is nudging people to donate by making donations relevant to an activity someone is doing - so the behavioral aspect. The difference is we're specifically focusing on peer to peer cash transfers rather than being charity agnostic. Given, I think, the alignment of intentions, will reach out to Ari and Nick in case they have helpful insight into what Jeremy and I are trying to do.
