In 1989, the Soviet Union traded 17 submarines, a cruiser, a frigate, and a destroyer to PepsiCo in exchange for Pepsi. For a brief moment, Pepsi had more firepower than most countries.
In 2003, a team spent years casing the Antwerp Diamond Centre's "uncrackable" vault. They defeated 10 layers of security including infrared sensors, seismic detectors, and a 100-million-combination lock. They stole $100M+ in diamonds. Then one member left his sandwich at the scene.
Elizabeth Holmes dropped out of Stanford at 19 with an idea: miniaturize blood testing. Instead of drawing vials of blood with needles, her company would use a finger prick — a single drop — to run hundreds of diagnostic tests. Results would come back in minutes, not days. Testing would cost a fraction of the current price.
If it worked, it would revolutionize healthcare. It would make diagnostics accessible to billions of people who lacked access to labs. It was, Holmes repeatedly insisted, the most important thing she would ever do.
Holmes modeled herself on Steve Jobs — down to the black turtleneck, the obsessive secrecy, and the belief that willpower could bend reality. The difference was that Jobs shipped products that worked.
Holmes's genius wasn't scientific. It was social. She assembled a board of directors that read like a state dinner guest list: Henry Kissinger, George Shultz (former Secretary of State), James Mattis (future Secretary of Defense), Sam Nunn (former senator), William Frist (former Senate Majority Leader and a physician).
None had expertise in blood diagnostics. But their names gave Theranos an aura of unimpeachable credibility. When Walgreens considered partnering with Theranos, they were shown the board list and stopped asking technical questions.
Theranos's board included two former Secretaries of State, a future Secretary of Defense, multiple former senators, and several retired generals. Not one had expertise in blood testing or laboratory science.
The Edison — Theranos's proprietary testing device — was fundamentally flawed. It could perform a small number of immunoassay tests with a finger-prick sample, but the results were unreliable. For the vast majority of the 200+ tests Theranos offered to patients, the company secretly diluted the tiny blood sample and ran it on modified commercial analysers made by Siemens.
The dilution introduced errors. The finger-prick collection method introduced variability. The results were often wildly inaccurate.
Employees who raised concerns were silenced or fired. The company's chief scientist, Ian Gibbons, was pressured not to testify in a patent lawsuit. He died by suicide in 2013.
In October 2015, John Carreyrou of the Wall Street Journal published a devastating investigation based on tips from former employees. He revealed that Theranos was running most of its tests on conventional machines, that the Edison produced unreliable results, and that the company had gone to extraordinary lengths to conceal these facts.
Holmes went on the offensive. She appeared on CNBC, CNN, and the Today Show to deny everything. Theranos hired David Boies (one of America's most prominent lawyers) to intimidate sources and threaten legal action against the Journal.
Carreyrou's primary source was Tyler Shultz — the grandson of board member George Shultz. Tyler had worked at Theranos and tried to raise concerns internally. When he went to the press, his own grandfather sided with Holmes over his grandson. The family rift lasted years.
It didn't work. The FDA, CMS (Centers for Medicare and Medicaid Services), and SEC all launched investigations. Theranos voided two years of test results — tens of thousands of potentially incorrect diagnoses. In 2018, Holmes was indicted on federal fraud charges.
In January 2022, Elizabeth Holmes was found guilty of four counts of fraud. She was sentenced to more than 11 years in federal prison. She reported to a minimum-security facility in Bryan, Texas, in May 2023.
Theranos had raised over $700 million from investors. The money is gone. The technology never existed. And somewhere in the wreckage, patients received blood test results that told them lies about their own bodies.
Holmes pitched a revolution in healthcare — cheap, fast, painless blood testing. The idea was so good that nobody checked if it was real.
The board she assembled made the lie almost impossible to question.

Holmes fought back with everything she had. It wasn't enough.
