GiveDirectly is driving a re-evaluation of the assumptions underlying international philanthropy with a provocative model: we deliver donations directly to the extreme poor and let them decide what to do with them. This approach builds on two converging trends: the rapid spread of electronic last-mile payments solutions in the emerging markets, and the large body of experimental evidence showing that direct transfers are as or more cost-effective at reducing poverty than more traditional, top-down approaches. GiveDirectly’s field operations utilize state-of-the-art technology and business processes to deliver transfers securely, efficiently, and transparently. Our unorthodox approach – allowing the poor, and not the donor, to choose where they invest – has prompted debate in the popular press and among policy makers.
