Entrepreneurs create new value by spotting unmet needs, taking risks, and assembling people and resources around an opportunity. Sometimes that means inventing something new; other times it means solving an old problem better than anyone else.

Economically, entrepreneurship matters because it drives innovation, job creation, and competitive pressure. It is one of the main ways economies renew themselves instead of simply repeating what already exists.
