Elizabeth Holmes’ Partner’s Net Worth: How Much Money Billy Evans Has – Hollywood Life

Billy Evans comes from the family behind San Diego’s Evans Hotels and has built a career in tech, including launching a biotech startup of his own. His family’s money comes up in A24’s You Can See Everything, now playing in theaters. The documentary, co-directed by Nathan Fielder and Lance Oppenheim, follows Evans and his longtime partner, former Theranos CEO Elizabeth Holmes, in the weeks before she reported to federal prison in 2023.

In a scene featured in the trailer, Nathan asks Billy whether he ever considered that Elizabeth might be scamming him. “What did she have to gain from me?” Billy replies. When Nathan brings up his family’s wealth, Billy says, “I think there’s a lot of different levels of wealth.” Billy addressed the film in his first TV interview, which aired November 15 on CBS Sunday Morning. He said he took a risk letting Nathan film in his home for 34 days and that he would still make the documentary again with the same people.

Since Elizabeth’s rise and fall as the tech world’s most famous self-made female billionaire, many are wondering what her partner, Billy, does for a living and where his own net worth stands today.

Here’s what we know about Elizabeth’s partner Billy’s fortune and how he makes a living while she serves her prison sentence.

What Does Elizabeth Holmes’ Partner, Billy Evans, Do for Work?

Billy is the heir to a luxury hotel in San Diego, California, but he has dedicated his life to founding startups. He once founded a business geared toward concierge medical travel for wealthy American and Chinese clients, though the startup didn’t last.

Eventually, Billy founded his current company, Haemanthus, a diagnostics company developing technology designed to analyze blood, saliva and urine to test for any signs of diseases. While this sounds startlingly familiar to Theranos, Haemanthus denounced that rumor and clarified what it really does.

“This is not Theranos 2.0,” the company tweeted in May 2025. “Theranos attempted to miniaturise existing tests. Our approach is fundamentally different. We use light to read the complete molecular story in biological fluids, seeing patterns current tests can’t detect. Not an improvement. A different paradigm.”

According to ABC News, Haemanthus raised $3.5 million from close friends and family members before rising to $15 million in funding altogether. Billy is hoping to stack that funding up to $50 million, the outlet reported in 2025.
