A Social business is a cause-driven business. It must be financially sustainable and mission-oriented. The company must achieve its social objective and at the same time cover all costs through a revenue model. The success of the business is not measured by the amount of profit made in a given period, but the impact of the business on people or the environment.
Investments in social businesses purely support the accomplishment of a social objective, and an investor should desire no financial gain. In fact, in a social business, investors/owners can gradually recoup the money invested, but cannot take any dividend beyond that point. Examples of social objectives are: healthcare for the poor, housing for the poor, financial services for the poor, nutrition for malnourished children, safe drinking water, renewable energy, etc.
