Why a High School Dropout's Staffing Company Is in a Class of Its Own Taso Du Val's Toptal helps businesses find the software know-how they need.

Check out the rest of the 2015 young millionaires here.

School isn't for everyone. Richard Branson dropped out at 16, and he's doing just fine. David Karp quit school at 15, and 11 years later he sold his blogging platform Tumblr to Yahoo for $1.1 billion. Hell, Benjamin Franklin's formal education concluded when he was just 10, and he's enshrined on the $100 bill.

Now we can add software savant Taso Du Val to the list. After dropping out of high school to pursue his passion for technology, he gained real-world experience as a lead engineer at photo-sharing startup Fotolog, which ad network Hi-Media purchased in 2007 for $100 million. From there he accepted a lead engineering position at another early-stage tech firm—PayPal co-founder Max Levchin's social media company Slide, acquired by Google in 2010 for $228 million.
