So far, D-Rev says, they've had a pretty easy time finding companies to participate. For one, D-Rev already has evidence that low-cost, high-utility products can help the poor and make companies money. Founder Paul Polak's previous organization, International Development Enterprises, created $25 irrigation pumps for small farmers-and helped local entrepreneurs sell millions of them. For another, D-Rev's corporate partners can make an even bigger profit by turning around and selling their new product (like this D-Rev-aided LED flashlight) to wealthier Americans. Efficient, affordable, useful technology, after all, is good for everyone.
