Komodo Health is building the Healthcare Map, the industry's largest and most complete view of the U.S. healthcare system by combining de-identified real-world patient data with innovative algorithms and clinical expertise. The company helps healthcare partners unlock critical insights to track patient behaviors, identify care gaps, and reduce disease burden.
