US EditionElizabeth Holmes' Partner Pursues New Blood-Testing Venture Echoing Theranos
- As of May 2025, Billy Evans, who is in a relationship with Elizabeth Holmes—the imprisoned founder of Theranos—is heading a new U.S.-based startup named Haemanthus.
- Evans started Haemanthus to provide disease detection through a device analyzing blood, saliva, and urine that echoes the ambitious promises of Theranos, whose fraud led to Holmes' 11-year prison sentence.
- Haemanthus markets itself as offering a radically new diagnostic approach, aims to begin with pet health testing before expanding to humans, and plans to raise over $50 million for development.
- Investor Jim Breyer declined to fund Haemanthus, citing concerns similar to those that made his team twice pass on Theranos, while marketing materials call the company “the future of diagnostics.”
- The development of Haemanthus suggests continued investor interest in blood-testing innovation despite Holmes’ fraud conviction, but launch timing remains uncertain and skepticism persists.
