Numen

Numen is a San Francisco company in the YC directory under diagnostics, machine learning and biotech, with the one-line mission of engineering a future without cancer deaths. Its public materials describe early-detection work but give little technical detail, so mechanism and evidence are not recorded here. The YC directory lists it at growth stage with a team of about 18. Included because cancer detection is its stated purpose; treat the record as thin until the company publishes more.
