What type of social enterprise are you looking to join?
Social Business: is a cause driven business according to Muhammad Yunus of the Yunus Centre (Yunus Centre: Social Business). "In a social business, the investors/owners can gradually recoup the money invested, but cannot take any dividend beyond that point...Sustainability of the company indicates that it is running as a business. The objective of the company is to achieve social goal/s."
L3C: According to the Non-Profit Law Blog, "the low-profit, limited liability company, or L3C, is a hybrid of a nonprofit and for-profit organization. More specifically, it is a new type of limited liability company (LLC) designed to attract private investments and philanthropic capital in ventures designed to provide a social benefit. Unlike a standard LLC, the L3C has an explicit primary charitable mission and only a secondary profit concern. But unlike a charity, the L3C is free to distribute the profits, after taxes, to owners or investors."
Social Finance: a movement based on the belief that financial innovation can be used directly to help society’s neediest people. (The Economist, Financial Innovation and the Poor, Sept. 25, 2009.)
B Corporation: A term coined by B Lab, “Certified B Corporations are a new type of corporation which uses the power of business to solve social and environmental problems. B Corps are unlike traditional businesses because they meet comprehensive and transparent social and environmental performance standards, meet higher legal accountability standard and build business constituency for good business.” (B Lab: B Corps.)
Flexible Purpose Corporations: A bill, S.B. 1463, is currently being brought before the California legislature that would introduce a new entity: the Flexible Purpose Corporation (FPC). Traditional corporations are obligated to put profitability above all else. The FPC allows corporations more leeway in pursuing “special purposes” or social and environmental missions.
