Ramesh “Sunny” Balwani began his career in the tech industry after earning a degree in computer science from the University of Texas at Austin. He initially worked at Microsoft as a software engineer before moving into more entrepreneurial ventures, including a stint at Lotus Software. His big break came when he joined CommerceBid, an e-commerce startup, where he served as president and helped steer the company through its acquisition by Commerce One in 1999. This early success positioned him as a savvy businessman with a knack for navigating the fast-paced world of Silicon Valley startups.

Balwani later became widely known for his role as president and COO of Theranos, the controversial blood-testing company founded by Elizabeth Holmes.

Balwani’s leadership at the company, however, came under scrutiny as allegations of fraud and mismanagement emerged, leading to his eventual indictment alongside Holmes. His rise and fall at Theranos cemented his place in Silicon Valley lore as a central figure in one of its most infamous scandals.
