Haemanthus technology

Haemanthus uses Raman spectroscopy with lasers to analyze blood samples, a patent granted January 21, 2025.
Raman spectroscopy
Raman spectroscopy measures molecular vibrations by shining light on samples, a technique discovered by C. V. Raman in 1928.
Expert opinion
UC Irvine professor Eric Potma says Haemanthus has legitimate engineers pushing Raman detection technology forward.
Funding and challenges
Haemanthus raised $3.5 million from friends and family and aims for $20 million in funding by 2025.
Regulatory status
Haemanthus claims no regulatory oversight for veterinary diagnostics but faces USDA oversight.
Stealth mode
Haemanthus operates in stealth mode with private home addresses in Austin, Texas.
Future plans
