The story of Mark Zuckerberg, who launched Facebook in 2004 from his Harvard dorm room and is now estimated to be worth 31.6 billion, is familiar to many. Although his current net worth at age 29 is staggering, the amount of young adults who have made millions of dollars after coming up with popular and innovative websites and web-based businesses is greater than you might think.

There are dozens of individuals who have made millions of dollars by the age of 25 in the tech world, including people who had a great idea for a website and the technical savvy or connections and friends to make their ideas a reality. Aside from the famous Zuckerberg, here are ten other people who launched a website that with some hard work and a little luck, earned them millions by their 25thbirthdays.

1. Sean Belnick (, $42 million)

In 2001, at age 14, Belnick launched a website – with the help of a $500 investment from a family member – to sell chairs online. Three years later, his business had made him a millionaire and he moved into a large commercial warehouse space. After he graduated from business school in May 2009, he took on a role as the company’s CEO. In 2012, the company’s revenue was $129 million and Belnick currently has a net worth that is estimated to be around $42 million.

The site began as an online community that was meant for girls who feel they have outgrown more childish topics such as Barbie, but are still too young to talk about teenage issues or interact in teen environments. This online community fulfills this niche market by enabling tweens to socialize, talk, take polls, enter contests, ask for advice, and publish stories within a safe environment. Now at age 25, Brindak is still the CEO of the website and is worth an estimated $30 million.

Her then-boyfriend (now husband) helped her set up the ecommerce site and she hired one part-time employee to help her package and ship the orders.
