Social enterprises are social mission driven organizations which apply market-based strategies to achieve a social purpose. The movement includes both non-profits that use business models to pursue their mission and for-profits whose primary purposes are social. Their aim – to accomplish targets that are social and or environmental as well as financial – is often referred to as the triple bottom line. Many commercial businesses would consider themselves to have social objectives, but social enterprises are distinctive because their social or environmental purpose remains central to their operation.

Rather than maximizing shareholder value, the main aim of social enterprises is to generate profit to further their social and or environmental goals. This can be accomplished through a variety of ways and depends on the structure of the social enterprise. The profit from a business could be used to support a social aim, such as funding the programming of a non-profit organization. Moreover, a business could accomplish its social aim through its operation by employing individuals from disadvantaged backgrounds or lending to micro-businesses that have difficulty in securing investment from mainstream lenders.

Many non-profit organizations see social enterprise as a way to reduce their dependence on charitable donations and grants while others view the business itself as the vehicle for social change. Whether structured as nonprofits or for-profits, social enterprises are simply launched by social entrepreneurs who want to improve the common good and solve a social problem in a new, more lasting and effective way than traditional approaches. They are conceived and operated by visionary entrepreneurs who recognize potential where others may not see it and who apply discipline, pragmatism, courage and creativity to pursue their solution in spite of all obstacles, toward a world that is more abundant, secure and inclusive for all.
