Hammurabi

Hammurabi is an AI-powered medical stop loss underwriting platform and managing general underwriter (MGU) for employer health care. Developed by multidisciplinary scientists from UC Berkeley's SkyDeck program with expertise in complex systems, public health, and machine learning, Hammurabi's proprietary neuro-semiotic models predict employer health risk with speed and precision — reducing standard underwriting timelines from days to minutes. The platform serves self-insured employers (through the Club Hammurabi membership program), insurance brokers and producers, and insurance carriers seeking better loss ratios. Key features include instant stop loss underwriting decisions, AI-driven medical expense prediction using demographic data, benefits administration, and digital health services. In February 2026, Hammurabi was established as a formal division of Xchange Benefits LLC, a subsidiary of Octave Specialty Group (NYSE: OSG). The Hammurabi platform is backed by Berkeley SkyDeck Fund, InsurTech NY, and Plug and Play Tech Center.
