About
Mantis Biotech is a YC-backed AI company that builds digital twins of human physiology to synthesize diverse, realistic clinical trial populations. The company addresses one of drug development's most persistent problems: clinical trials consistently underrepresent women, elderly patients, and minorities, producing efficacy data that fails to predict real-world outcomes across populations. Mantis's AI platform generates synthetic patient data that fills these representation gaps.
