Summary
Haemanthus, a blood-testing startup founded by Billy Evans, was identified through marketing materials reviewed by The New York Times in 2025 and spotlighted by the new documentary “You Can See Everything.”
The company describes itself as offering “a radically new approach to health testing,” clarifying the vague business activity Evans had previously described only as investing and starting companies.
The roughly 3-hour film follows Evans and Elizabeth Holmes with unusual access, including the period before Holmes reported to prison in May 2023.
That backdrop gives the venture added scrutiny because Holmes, the former Theranos founder, is serving a sentence for defrauding investors over blood-testing technology claims.
