A social business is an organization or business entity that operates non-commercially. In other words, the main motive is not profit but social welfare.
Social businesses exist to solve the social problems that people face, for example, by providing education, housing, and health.
The owner invests a sum of money but cannot take out dividends beyond the initial investment. Once the initial investment returns, investors don’t take profits anymore. It remains in the business to expand its reach and increase social impact.
