Someone who accepts the risks and rewards of developing, launching, and running a new business is often called an entrepreneur. But this is narrow thinking.
Per Wikipedia’s latest entry, “Entrepreneurship” is broadly defined as the creation of value. Wikipedia states that entrepreneurs “are leaders willing to take risk and exercise initiative, taking advantage of market opportunities by planning, organizing and deploying resources, often by innovating to create new and improving existing products or services.” Entrepreneurs often are called solopreneurs, freelancers and self-employed (that represent about 30% of the US workforce) because initially they work by themselves with a specialized skillset to establish creation of value.
