Five Tools for Social Entrepreneurs Want to start a business, plus do some good in the world? Here's a list of resources.

Social entrepreneurs use business ventures as a means to solve the world's most complex problems.

These days, a growing number of social entrepreneurs are building for-profit business models, bypassing government association and the confining structure of the nonprofit classification. In a number of states, including California and New York, entrepreneurs can now form so-called B Corporations, which allow company directors to weigh social missions over financial returns.

As a result, more tools are popping up to aid the socially conscious business owner. Here are five resources designed to help do-good entrepreneurs get their enterprises off the ground and into the black.
