A person who organizes, operates, and assumes the risk for a business venture is a/an _____?

An entrepreneur is an individual who takes on the initiative to establish and run a business. This role involves not only the organization and operation of the venture but also a significant level of risk, as entrepreneurs invest their own resources and capital into the business. They are responsible for making strategic decisions that shape the direction of the company and are often driven by innovation and the desire to fulfill unmet needs in the market.

While managers are crucial for the day-to-day operations of a business, they typically execute the vision set by an entrepreneur rather than taking on the initial risks or ownership of the business. Investors provide financial backing but do not generally engage in the daily operations or management of the business. Employees perform specific tasks or roles within the organization and do not bear the risks associated with business ownership. Thus, the definition of an entrepreneur aligns perfectly with the description given in the question.
