She Faked a Revolution in Blood Testing

Choose your depth

In 2003, a 19-year-old Stanford dropout named Elizabeth Holmes founded a company called Theranos with a promise that sounded like science fiction: a device the size of a breadbox that could run hundreds of blood tests from a single finger prick — no needles, no vials, results in minutes.

By 2013, Theranos was valued at $9 billion. Holmes was worth $4.5 billion on paper, the youngest self-made female billionaire in the world. She was on the covers of Forbes, Fortune, and Inc. She had convinced Henry Kissinger, George Shultz, James Mattis, and Rupert Murdoch to serve on her board or invest their fortunes.

There was one problem: the technology didn't work.

THE LIE

Theranos's proprietary device, the "Edison," could perform only a handful of the 200+ tests Holmes promised. For most tests, the company secretly diluted finger-prick blood and ran it on commercial machines made by Siemens — often producing dangerously inaccurate results.

Patients received wrong diagnoses. Some were told they had conditions they didn't have. Others were told they were healthy when they weren't. The company concealed the failures, bullied whistleblowers, and spent more money on lawyers than on research.

In 2015, Wall Street Journal reporter John Carreyrou published an investigation that unravelled everything. In 2022, Elizabeth Holmes was convicted of fraud. She reported to prison in May 2023 to begin an 11-year sentence.
