Ramesh “Sunny” Balwani

Balwani was born into a Sindhi Hindu family in Pakistan in 1965 and later studied in the United States.⁠[2]

Balwani earned an undergraduate degree at the University of Texas at Austin and an MBA at the University of California, Berkeley. He later attended Stanford University’s computer-science program without completing it.⁠[3]

Balwani worked in sales at MicrosoftMicrosoftMicrosoft is a technology company founded by Bill Gates and Paul Allen in 1975 and headquartered in Redmond, Washington, with businesses spanning Windows, Microsoft 365, Azure, enterprise software, artificial intelligence, gaming and devices.Open the full entry and became CommerceBid’s president in 1999. Commerce One subsequently acquired the business; his reported proceeds from selling the resulting shares were about $40 million.⁠[4]

Balwani met eighteen-year-old Holmes in a Beijing Mandarin program when he was thirty-seven.⁠[5]

Divorced Keiko Fujimoto in December 2002.⁠[6]

Balwani and Holmes lived together from 2005 to 2016 in an on-and-off romantic relationship. Their relationship overlapped with their management of Theranos, but he was not the company’s founder.⁠[7]

Balwani said he lent Theranos $13 million interest-free in 2009.⁠[5]

Balwani joined Theranos in September 2009 after guaranteeing a credit facility. As president and chief operating officer, he oversaw software, personnel and day-to-day operations, shared major decisions with Holmes and presented the company’s technology and finances to investors. The SEC dates his executive tenure through May 2016; the Justice Department describes his employment as lasting through July.⁠[8][1]

Trial evidence showed that Balwani and Holmes knew their analyzer performed only a few tests while representing that Theranos largely used its proprietary equipment. They also overstated pharmaceutical validation, military use, retail expansion and revenue. The Justice Department recorded that Balwani held nearly thirty million Theranos shares, more than six percent of the company; that historical stake was not equivalent to subsequently realizable wealth.⁠[1]

In March 2018, the SEC sued Balwani, Holmes and Theranos, alleging they had raised more than $700 million through misrepresentations. Holmes and the company settled at that time; Balwani did not join that settlement. Federal criminal charges followed in June, and a 2020 superseding indictment set out two wire-fraud conspiracy and ten wire-fraud counts.⁠[9][1]

Holmes testified that Balwani had emotionally and sexually abused her; his lawyer Jeffrey Coopersmith denied the allegations.⁠[10]

Following a separate trial lasting about four months, a jury convicted Balwani on all twelve counts: two conspiracies involving investors and patients and ten wire-fraud counts. His verdict differed from Holmes’s acquittals on certain patient-related counts.⁠[1]

U.S. District Judge Edward Davila sentenced Balwani to 155 months in prison—twelve years and eleven months—followed by three years of supervised release. Patient-testing consequences and investor losses were central to the Justice Department’s sentencing account.⁠[1]

The court held Balwani and Holmes jointly and severally liable for $452,047,268 in restitution, covering twelve investor-victim groups plus Safeway and Walgreens. The order established a payment obligation, not proof that victims subsequently recovered those amounts.⁠[11]

The Ninth Circuit affirmed the convictions, sentences and restitution order on February 24, 2025, followed by an amended opinion on December 22. Balwani petitioned the U.S. Supreme Court on May 21, 2026. The Court denied review on October 5; Justice Clarence Thomas did not participate.⁠[12][13]
