The world's most exciting, fastest-growing new market is where you least expect it: at the bottom of the pyramid. The last couple of decades have seen great increases in sales, now multinational corporations are seeing markets with sluggish or no growth. One market that's been overlooked is also the fastest growing market in the world, and it's where you least expect it: at the bottom of the pyramid. Collectively, the world's 5 billion poor have vast untapped buying power. They represent enormous potential for companies who learn how to serve this market by providing the poor with what they need. This creates a win-win situation: not only do corporations tap into a vibrant market, but by treating the poor as consumers they are no longer treated with indignity; they become empowered customers. Corporations who service this market form an economic infrastructure, which creates real jobs for the poor, and finally an end to the vicious cycle of poverty.
