Entrepreneur and intrapreneur.
An entrepreneur assumes the risk of owning and operating a business in exchange for financial and other rewards that the business may produce. By contrast, an intrapreneur is a person employed by an organization whose compensation is based, at least in part, on the financial success of the unit for which he or she has responsibility.
Intrapreneurs, by definition, embody the same characteristics as the Entrepreneur, conviction, passion, and drive. The more the Intrapreneur expresses himself, the more the company is forced to confront its own effectiveness. If the company is supportive, the Intrapreneur succeeds. When the organization is not, the Intrapreneur usually fails or leaves to start a new company.
