Who is someone that assumes the responsibility, risk, and rewards of starting and operating a business?

An entrepreneur is someone who takes on the responsibility of starting and operating a business, which includes assuming the associated risks and rewards. This role involves identifying opportunities, innovating products or services, and making strategic decisions that will impact the business's success. Entrepreneurs are often seen as the driving force behind economic growth, as they not only create new businesses but also contribute to job creation and the overall dynamism of the market.

In contrast, an investor provides capital to a business but does not typically engage in the day-to-day management or operational decisions, which distinguishes them from an entrepreneur. A manager is responsible for overseeing the operations of a business but does not necessarily own or bear the financial risks associated with starting that business. An owner may have financial investment in the company and potentially operate it, but the term "entrepreneur" more specifically reflects the innovative and risk-taking aspects of starting a new venture.
