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. GiveDirectly has been featured on NPR’s This American Life, and in Foreign Affairs, The Economist, and The New York Times.
