Ramesh Balwani

Ramesh "Sunny" Balwani is a businessman who was the former president and chief operating officer of Theranos, which was a privately held health technology company founded by his then-girlfriend Elizabeth Holmes. He and Holmes fraudulently represented that they had devised a revolutionary blood test that required only small amounts of blood, such as from a fingerstick. Both Balwani and Holmes were convicted of fraud. The consequences of the fraud led to the collapse of Theranos and the loss of billions of dollars to investors.
