Bad Blood by John Carreyrou is a must-read book for every startup founder. It shows exactly what happens when an entrepreneur has no values.
Theranos founder and CEO Elizabeth Holmes cared about nothing but herself and her image, and as a result, she was willing to betray everyone she came across. She hurt so many people in the process, jeopardized the lives of patients, squandered huge amounts of capital, and wound up with nothing to show for it.
