THE FIRST SELF-MADE BILLIONAIRE WOMAN
Real Time Net Worth
At 30, Elizabeth Holmes makes her debut on the Forbes 400 as the youngest self-made woman billionaire. She dropped out her sophomore year of Stanford to found Palo Alto, Calif.-based blood testing company Theranos in 2003 with money she saved for college. With a painless prick, her labs can quickly test a drop of blood at a fraction of the price of commercial labs which need more than one vial. Theranos has raised $400 million from venture capitalists, valuing the company at $9 billion, and Holmes' 50% stake at $4.5 billion. She has assembled a stellar board that includes elder statesmen George Shultz and Henry Kissinger. Last year, Walgreens, the largest U.S. retail pharmacy chain, with more than 8,100 stores, announced plans to roll out Theranos Wellness Centers inside its pharmacies.
