A Silicon Valley home associated with a tragic chapter of the Theranos scandal has been sold for $5 million. The Portola Valley, California, property was purchased by Rochelle Gibbons, the widow of Theranos chief scientist Ian Gibbons, in May 2025. The sale occurred quietly, largely unnoticed by the public.
The house, located at 831 La Mesa Drive, is the same residence where Ian Gibbons died by suicide in 2013. At the time of his death, he was reportedly under significant pressure regarding the startup's technology and was expected to testify about it.
Property records indicate the Gibbons purchased the three-bedroom, 3.5-bathroom home in 1990 for $785,000. The property underwent renovations by Rochelle Gibbons before being listed.
The renovated home, spanning 3,074 square feet on a quarter-acre lot, was listed on April 21 for $4.65 million. It received an offer within 10 days and closed on May 19 for $5 million, $350,000 above the asking price. The house features heated concrete floors, a chef's kitchen, and walls of glass. The backyard includes a pool surrounded by mature landscaping.
Ian Gibbons, a Cambridge-educated biochemist with over 60 patents, was Elizabeth Holmes' first significant scientific hire in 2005. He soon became disillusioned with Theranos' blood-testing technology, confiding to his wife that "nothing was working." He felt trapped, as he believed admitting the technology's flaws would cost him his job. Holmes, meanwhile, was listed as a co-inventor on patents that incorporated much of his work.
In 2013, Gibbons was subpoenaed for a patent dispute but was reluctant to detail the technology's functionality, concerned about its readiness for public use. He died on May 23, 2013, at age 67, after an overdose of medication led to liver failure.
Following his death, Theranos demanded the return of company materials from his widow and threatened her for speaking to the press. Rochelle Gibbons, a scientist and patent attorney herself, became a vocal figure in the reporting that exposed the $9 billion company's fraudulent practices.
The story of Ian Gibbons was dramatized in Hulu's 2022 miniseries "The Dropout," with actor Stephen Fry portraying him.
Elizabeth Holmes is currently serving an 11-year prison sentence for fraud. She is scheduled to move to a Texas halfway house in 2027. Holmes has also recently appeared in a documentary discussing a potential "Theranos 2.0" venture with her partner, Billy Evans.
