The person who creates an organization or a company is known as the founder. Founder is also a verb meaning "fail miserably," which is something a company's founder hopes the company will never do.
As a noun, founder means "the beginner or originator of something." You might talk about the founder of a nation, the founder of club, or the founder of a website. As a verb, founder can mean “stumble,” like when you trip and fall, but more generally it means "collapse or fall apart." A sports team might founder by slumping on a ten-game losing streak; a ship that sinks in a bad storm can be said to have foundered at sea.
