The main difference between starting a social business and a regular business is the motivation of the entrepreneur. In a regular business, the main goal is to make money, while in a social business, the goal is to solve a social problem. Social businesses aim to break even and have investors who are willing to wait for a return on their investment. The focus is on making a positive impact on society rather than maximizing profits. The time it takes for a social business to become sustainable may be longer, as the priority is on achieving social goals rather than quick financial gains.
