A Silicon Valley startup promised to run hundreds of tests from a few drops of blood. Investors poured in hundreds of millions of dollars. Patients trusted the results. There was just one problem: the technology allegedly didn't work the way the world was told.
That's the story John Carreyrou tells in Bad Blood. He is the Wall Street Journal reporter who broke the Theranos story, and he wrote the book from inside the investigation. Former employees talk. Internal doubts surface. Powerful people stay loyal anyway. It reads like a thriller, and it happens to be true.
What makes it stand out is the reporting. Carreyrou shows how a charismatic founder, Elizabeth Holmes, built a company on secrecy, legal threats and big promises. He also shows how a handful of insiders found the nerve to push back.
The story didn't stop at the last page. Holmes was convicted in January 2022 on four counts of fraud and conspiracy related to investors, and she was sentenced to more than eleven years in prison. The courts have been part of the aftermath ever since. So how does a company this shaky fool so many smart people for so long?
