Raising Funds

Theranos's business model was based around the idea that it ran blood tests using proprietary technology that required only pinprick in your finger and a small amount of blood. Holmes said the tests would be able to detect medical conditions like cancer and high cholesterol.

Holmes started raising venture capital money for Theranos from prominent investors like Draper Fisher Jurvetson and Larry Ellison. To date, Theranos has raised more than $700 million.

Holmes took investors' money on the condition that she wouldn't have to reveal how Theranos' technology worked. Plus, she would have final say over everything having to do with the company.
