Bad Blood: Secrets and Lies in a Silicon Valley Startup (Summary)

by John Carreyrou

Imagine a revolutionary blood-testing device that could run hundreds of tests from a single drop of blood. Now imagine that device is a sham, and to fool investors and partners like Walgreens, the company is secretly using off-the-shelf machines from its competitors, diluting tiny blood samples to work in them, and delivering faulty results to real patients. That wasn't a hypothetical; it was the daily reality inside Theranos, one of Silicon Valley's biggest and most dangerous frauds.

A Compelling Narrative Can Trump Hard Data

Founder Elizabeth Holmes's charisma and compelling story of revolutionizing healthcare, combined with her black turtleneck uniform consciously modeled after Steve Jobs, allowed her to charm powerful investors, politicians, and board members who overlooked the glaring lack of scientific evidence.

Theranos assembled a star-studded board including Henry Kissinger and former Secretary of State George Shultz. Shultz's own grandson, Tyler, who worked at the company, tried to warn him about the fraud, but the elder Shultz was so captivated by Holmes's narrative that he sided with her over his own family, a testament to her manipulative power.

Fear and Intimidation Are Toxic Management Tools

Elizabeth Holmes and her partner Sunny Balwani ruled through secrecy and intimidation, firing anyone who questioned the technology and creating a siloed environment where departments were forbidden from communicating, ensuring no one could see the full picture of the fraud.

Ian Gibbons, Theranos's chief scientist, was a brilliant biochemist who knew the technology was a fantasy. Facing pressure to lie in a patent lawsuit, he committed suicide. The company's only response was to have its lawyers call his widow and demand she immediately return all of his confidential company property.

"Fake It Till You Make It" Is Deadly in Healthcare

Silicon Valley's famous mantra of launching imperfect products and iterating later is fundamentally dangerous when applied to medicine, where people's lives are at stake. Theranos applied a software mindset to a hardware and science problem, with catastrophic results.

To secure a partnership with Walgreens, Theranos faked a live demonstration for the pharmacy giant's executives. The "results" they showed were not actually from their Edison machine in the room; they were pre-recorded from a previous test. The machine itself produced an error message that Holmes quickly hid from view, a blatant deception that won them a massive deal and put their non-working tech in real stores.

Whistleblowers and Journalism Are Critical Checks on Power

Despite the immense legal and financial pressure exerted by Theranos, a few brave whistleblowers and the author's investigative journalism at The Wall Street Journal were ultimately responsible for exposing the massive fraud to the world.

After his grandfather sided with Holmes, Tyler Shultz risked his career and family relationships by becoming a confidential source for Carreyrou. He was followed by private investigators and threatened by Theranos's infamous lawyer, David Boies, but his courage helped provide the internal proof needed to break the story.
