Wired profiles Holmes’s husband and his blood-testing startup Haemanthus
Wired reports that Billy Evans, husband of imprisoned Theranos founder Elizabeth Holmes, is building Haemanthus, a Raman spectroscopy diagnostics firm he says is not “Theranos 2.0.”
Wired on Sunday published a profile of Billy Evans, the husband of imprisoned Theranos founder Elizabeth Holmes, and of Haemanthus, the Austin diagnostics company he founded in 20221.
The magazine ties Evans to Nathan Fielder and Lance Oppenheim’s documentary You Can See Everything, in which, Wired says, Evans agrees on camera with a “Theranos 2.0” characterization even as he has told social media followers Haemanthus is not that1.
Holmes’s name does not appear on Haemanthus incorporation documents, Wired reported, and a person familiar with the business told The Wall Street Journal she is not involved1. Evans declined to be interviewed for the Wired story and did not answer specific questions1.
Public detail on the company is thin: Wired said it has released no products, has little web presence, and remains in what Evans has described as stealth1. Its stated aim is a countertop machine for blood, urine and saliva testing at home, using light and lasers rather than the miniaturized conventional assays Theranos pursued1.
A U.S. patent for a Raman Spectroscopy System was granted Jan. 21, 2025, Wired reported, describing a device that would fire high-power light into biological samples and read the resulting signal1. Raman spectroscopy is an established laboratory technique dating to work associated with C. V. Raman in 19281.
Eric Potma, a chemistry professor at the University of California, Irvine and a Haemanthus consultant, told Wired he would not discuss the work in depth but that, in his view, it is not Theranos1. “The engineers at Haemanthus are legit, and they are really trying to push the Raman detection technology into interesting directions,” he wrote1.
Wired said turning a sensitive lab method into a home appliance that could meet regulatory standards in seconds, as promotional materials have promised, remains a large engineering and compliance challenge1. Evans told the All-In podcast that meeting Holmes was the intention of the film and that he had not seen it1.
What the company has raised, how far a prototype has progressed, and whether Holmes will have any future role are not independently established in the Wired account beyond earlier press figures and the documentary’s on-camera scenes1.
