What is an 'Entrepreneur'. An entrepreneur is an individual who, rather than working as an employee, runs a small business and assumes all the risks and rewards of a given business venture, idea, or good or service offered for sale. The entrepreneur is commonly seen as a business leader and innovator of new ideas and business processes.
Being an entrepreneur is more about a state of mind than having a specific business idea. I subscribe to the Reid Hoffman and Ben Casnocha philosophy that an entrepreneur is someone who thinks of themselves as a startup.
