In 2014, Theranos founder Elizabeth Holmes was widely seen as the female Steve Jobs: a brilliant Stanford dropout whose startup “unicorn” promised to revolutionise the medical industry with a machine that would make blood tests significantly faster and easier. How did the investors not do their due-diligence at such scale? A wild, frightening ride into a broken Silicon Valley culture and psychology of a sociopath. A brave piece of investigative journalism too. Reads like a thriller.
