While some startups are bootstrapped, many others seek external funding to help with operating costs and growth plans. Big venture capital firms like Andreessen Horowitz or Sequoia Capital and accelerators like Y Combinator dominate most people's conceptions of the "typical" investor.
A number of popular retail startups, however, have investors who you might recognize from ventures that couldn't be more different from the world of Silicon Valley: movies and TV, music, and sports.
When they're not starring in your favorite shows, singing on stage, or winning championships, these celebrities are funneling their money into up-and-coming companies. They see potential in and care about the startups that are helping people live the lives they want to lead.
