Summary
Bad Blood tells the story of biotechnology startup Theranos, with a focus on founder Elizabeth Holmes. Theranos raised over $900M, at one point making Holmes the youngest self-made billionaire in the world (on paper at least). Much of it turned out to be fake, and she was recently convicted of fraud.
The story of Theranos is one of caution: what happens when a founder takes the “fake-it-til-you-make-it” approach too far, and a reminder to always think for yourself when evaluating people and hype.
