The Haven Diagnostics Story

Agent-based models have been coined a "Disruptive Innovation" by the National Institutes of Health and used to model the spread of infectious disease spread in hospitals, bioterrorism, and the spread of flu in the workplace.

In 2020, Haven adapted agent-based models to help employers measure in-office COVID-19 risk, align their executives, and communicate it to their employees. Our medical analytics platform helps people make data-driven decisions on returning to the office.
