Because the IRS requires us to route funds to entities that have an affiliated 501c3, we sometimes have to partner with organizations like AMHF which serve as financial conduits.
However, AMHF and other partners that play this role (Hope For West Africa in Nigeria also does this for a new pilot partner Faith Alive) do not take any cut of donations despite the enormous amount of work they do to help coordinate patient care and manage funds (a huge benefit, since foundations often have more experience with international transfers and disbursement than on-the-ground hospitals do).
Because of this, donating via Watsi is arguably as efficient (and possibly even more efficient from a donor's perspective because we pay the credit card processing fees) as donating to one of our partners directly.
With regard to the the fact that some of our partners also fundraise on a patient-by-patient basis themselves, we think that's awesome! Watsi is proving that truly transparent peer-to-peer giving is better than traditional "Donate Now" forms of giving, and we're ecstatic that our partners are adopting the model. In fact, down the line, we'd like to white label our platform so that partners can feature patients on their sites as easily as they can feature them on Watsi (CURE being the one exception, since they've done a great job of p2p giving or a while now).
