GiveDirectly allows governments, foundations, and individual donors to provide direct cash transfers to the extreme poor. Using the latest technology at every step, we locate recipients, integrate them into electronic payments networks, and monitor transfers end-to-end. We charge the full cost of delivering this service and nothing more. GiveDirectly holds the top overall rating for non-profit effectiveness by GiveWell and received the inaugural Google Global Impact Award. Our unorthodox approach – allowing the poor, and not the donor, to choose where they invest – has prompted extensive media debate with headlines ranging from “The Best and Simplest Way to Fight Global Poverty” (Slate) to “Can Four Economists Build the Most Economically Efficient Charity Ever?” (Atlantic) and “Is it Nuts to Give to the Poor Without Strings Attached?” (New York Times Magazine). We are looking for exceptional talent to help us build the world's most efficient, transparent and scalable system to transfer resources directly into the hands of the poor -- and in the process transform the way international development is done.
