#6. Elizabeth Holmes
Estimated net worth: $3.6 billion
Like Mark Zuckerberg, Elizabeth Holmes dropped out of an Ivy League university during her sophomore year to pursue her entrepreneurial dreams. At age 19, the ambitious chemical engineering major quit Stanford and bootstrapped Theranos, a revolutionary Palo Alto, Calif.-based blood diagnostics startup, mainly with money her parents saved for her college education.
The now-$9 billion company, poised to upend the $73 billion dollar diagnostics industry, was recently rocked by an explosive Wall Street Journal exposé. The tell-all alleges that Theranos has struggled with and neglected to use its proprietary fingertip-prick blood test technology. Holmes has hit back at the criticism, saying the company is awaiting FDA approval it will “absolutely” get. Source
