Yesterday Business Week announced the beginning of their second annual search for America’s Most Promising Social Entrepreneurs.  Business Week is looking for reader suggestions of U.S. based companies that are profitable while solving social issues at the same time.

We want to find entrepreneurs who are building profitable business models in which doing good is an intrinsic part of the business and not just a philanthropic sideline. Concepts are great, but for this roundup we just want to hear about companies that are up and running and willing to disclose annual revenues.

Suggestions will be taken until March 26, 2010 and narrowed down to 25 finalists.  Readers will have the chance to read about and vote for the finalists from May 4 to May 21.  The top 5 social entrepreneurs will be announced on June 1, 2010.  You can read about the 2009 social entrepreneur finalists or submit a suggestion now.
