The social enterprise—a sustainable business that creates social or environmental value alongside profit—is no longer a niche concept. Social entrepreneurs inhabit nearly every sector of the economy, from banking and insurance to energy and manufacturing. That breadth is evident in Bloomberg Businessweek's second annual U.S. roundup of promising social entrepreneurs. The companies profiled here were selected from more than 200 candidates suggested earlier this year by Businessweek.com readers. They range from fresh startups to established, multimillion-dollar enterprises. All share a commitment to using business to create a broader benefit.
