Elizabeth Holmes is the founder and former CEO of Theranos, a now-defunct health technology company. Theranos claimed to have revolutionized blood testing by developing testing methods that could use surprisingly small volumes of blood. However, it was revealed that the technology did not work as advertised. Holmes was subsequently charged with multiple counts of fraud for misleading investors, doctors, and patients.

Holmes's case has been closely watched as it casts a harsh light on Silicon Valley’s culture of hubris. She has been ordered to report to prison on May 30, 2023​ after losing her latest bid to remain free.
