A dorm room at Harvard, a garage in Washington state, a student’s room at the University of Texas: some of the world’s biggest companies began in places like these. The entrepreneurs who started them did not just build businesses; they changed how people shop, search, connect, travel, and work.

No single industry or background connects them. Some immigrated to the US as children, some dropped out of college to chase an idea, and some spent decades growing the same company until it became a giant. Together, they now hold a huge share of America’s wealth.

In this article, we’ll discuss the top 10 entrepreneurs in the United States, based on their history, ownership, and the kind of business they are known for. The ranking covers company founders and co-founders and uses net worth estimates from Forbes’ 2026 lists.
