Numen (formerly Cleancard) is a San Francisco biotech building rapid at-home cancer screens that read like a pregnancy test. By combining synthetic biology, machine learning, and computer vision, its platform detects multiple cancer biomarkers from a single urine sample in about 30 minutes, with no lab machinery required. Founded by Rhodes Scholars Thomas Carroll and Luca Springer, the company's first screens target prostate, bladder, and ovarian cancer, with a mission to drive cancer mortality toward zero.
