Overview

  • Haemanthus, founded by Billy Evans in 2024, claims its laser and AI-based device can analyze blood, saliva, and urine for diagnostics, starting with pet testing before human trials.
  • The company has raised millions and is seeking over $50 million in funding to develop and scale its diagnostic technology, described as 'the future of diagnostics.'
  • Marketing materials and a prototype photo show striking similarities to Theranos’ Edison machine, which was central to the fraud that led to Holmes’s conviction.
  • Public records confirm Haemanthus’s incorporation in Delaware and correspondence with the USDA indicates its product is outside veterinary regulatory jurisdiction.
  • Elizabeth Holmes, currently serving an 11-year prison sentence, is reportedly advising Evans on the venture, though Haemanthus denies her involvement.
