Bangladeshi villagers sharing cell phones helped build what is now a thriving company with more than $200 million in annual profits. But what is the lesson for the rest of the world? This is a question author Nicholas P. Sullivan addresses in his tale of a new kind of entrepreneur, Iqbal Quadir, the visionary and catalyst behind the creation of GrameenPhone in Bangladesh.

GrameenPhone—a partnership between Norway's Telenor and Grameen Bank, co-winner of the 2006 Nobel Peace Prize—defines a new approach to building business opportunities in the developing world. You Can Hear Me Now offers a compelling account of what Sullivan calls the "external combustion engine"—a combination of forces that is sparking economic growth and lifting people out of poverty in countries long dominated by aid-dependent governments. The "engine" comprises three forces: information technology, imported by native entrepreneurs trained in the West, backed by foreign investors.
