View gallery

William “Billy” Evans has remained by Elizabeth Holmes’ side through the collapse of Theranos, her fraud trial and her imprisonment. The hotel heir and entrepreneur met Holmes in 2017, and they share two children, a son born in 2021 and a daughter born in 2023. Holmes said in 2025 that she and Evans hadn’t officially married.

Holmes founded Theranos in 2003, promising to run numerous blood tests using only a small sample. The company, where her former boyfriend Ramesh “Sunny” Balwani served as president, attracted major investors and partnered with Walgreens before The Wall Street Journal exposed problems with its technology in 2015. Following her 2018 SEC settlement, Holmes was convicted in a separate criminal case in January 2022 of three counts of wire fraud and one count of conspiracy to commit wire fraud, all involving investors. She began serving her prison sentence in May 2023.

Evans has since pursued a biotech venture of his own. His startup, Haemanthus, is developing testing technology that uses small biological samples. Reports about the company in May 2025 drew comparisons to Theranos and renewed interest in Evans’ career.

Find out more about Evans, his relationship with Holmes and their family below.

Who Is William “Billy” Evans?

Evans is a technology entrepreneur and heir to the family behind San Diego-based Evans Hotels. His grandparents, Anne and William D. Evans, founded the company in 1953. Following William D.’s death in 1984, Anne became more involved in the business and brought their children, Grace Evans Cherashore and William L. Evans, onto the management team, according to the company’s website.

Evans and Holmes appear in the documentary You Can See Everything, which is now playing in theaters. His family’s wealth comes up in the trailer. After Evans questions what Holmes would have gained by scamming him, co-director Nathan Fielder asks, “Well, isn’t your family rich?” Evans replies, “I think there’s a lot of different levels of wealth.”

Evans graduated from the Massachusetts Institute of Technology and previously worked at Luminar, a company developing technology for self-driving vehicles. He later founded Haemanthus, a biotechnology startup developing testing technology using small biological samples. The venture attracted attention in May 2025 because of Evans’s connection to Holmes and comparisons to Theranos’s original ambitions.

How Did Elizabeth Holmes And Billy Evans Meet?

Holmes and Evans met at a Fleet Week charity event in the Bay Area in 2017, according to The New York Post. They initially developed a friendship, spending time cooking and hiking together before their relationship became romantic.

Evans proposed in 2018 after they attended a Taylor Swift concert, using a silver snake ring purchased at the show. Despite earlier reports of a 2019 wedding, Holmes confirmed in February 2025 that they had not officially married. “Maybe we’ll get married someday. But our bond is more than a piece of paper,” she told People.

What Does Billy Evans Do?

Evans is a technology entrepreneur and the founder of Haemanthus, a biotechnology startup. An MIT graduate, he previously worked at Luminar, a company developing technology for self-driving vehicles, before launching his own venture.

In May 2025, reports revealed that Haemanthus was developing technology to analyze blood, saliva and urine, with plans to begin with veterinary testing before expanding to humans. According to reporting from The New York Times, summarized by ABC News, the company had raised approximately $18.5 million from friends, family and other investors.

Elizabeth Holmes & Billy Evan’s Family: Do They Have Children?

Holmes and Evans have two children: a son, William Holmes Evans, born in July 2021, and a daughter, Invicta, born in February 2023. Holmes’s first pregnancy delayed her criminal trial, while their daughter arrived shortly before she began serving her prison sentence in May 2023.

In his November 15, 2026, interview with CBS Sunday Morning, Evans said he and the children visit Holmes every week. “I absolutely hate that my daughter’s first steps were in federal prison,” he told Matt Gutman. He said he tries to make the visits fun for the kids by turning small moments into games, like seeing how many acorns they can fit into a water bottle in the prison yard.

In a February 2025 interview with People, Holmes said Evans and the children were visiting twice a week at the time. She also recalled pumping breast milk for Invicta after reporting to prison. “It was important to me because it was a way to love her in here,” Holmes said.

“It kills me to put my family through pain the way I do.” She added, “But when I look back on my life, and these angels that have come into it, I can get through anything. It makes me want to fight for all of it.”

Is Elizabeth Holmes Still in Prison?

Yes. As of November 2026, Holmes is still serving her sentence at Federal Prison Camp Bryan in Texas, where she reported on May 30, 2023. However, she has been approved for a transfer to the Austin Transitional Center, a halfway house in Del Valle, Texas, on August 23, 2027, according to a Department of Justice victim notification reported by ABC News. The planned transfer would change where Holmes serves her sentence; it would not mark its completion. Her projected federal release date remains February 22, 2030.

Holmes was originally sentenced to 11 years and three months following her conviction on four investor-related fraud and conspiracy counts. A federal appeals court upheld her conviction in February 2025. In March 2026, a judge reduced her sentence by one year under revised sentencing guidelines for qualifying defendants without prior criminal histories, bringing it to 10 years and three months. Her conviction remains in place.
