College Dropouts Who Built Billion-Dollar Startups

But some of the most successful entrepreneurs in the U.S. have proven that breaking away from that path can sometimes lead to even greater success. College dropouts startup success stories are not just inspiring—they’re proof that passion, persistence, and bold ideas can be more powerful than a degree.

In this article, we’ll explore how some of the most famous and lesser-known college dropouts built powerful companies, reshaped industries, and inspired millions.


Why Do Some Entrepreneurs Drop Out of College?

Before diving into the stories, it’s important to understand why some drop out of college in the first place.

Common Reasons Include:

  • Chasing a Bigger Vision: Some students discover a business idea so powerful they can’t wait four years to start.
  • Lack of Real-World Learning: College doesn’t always teach practical skills needed to build a company.
  • Financial Constraints: College is expensive, and some choose to invest time and money into a startup instead.
  • Disruption Over Tradition: Entrepreneurs often dislike rules and prefer innovation over structure.

These reasons don’t mean dropping out is the key to success for everyone—but for some, it opened doors that a classroom never could.

  • Dropped Out of: Reed College
  • Founded: Apple Inc.
