About Us

Health Fidelity is a San Mateo, Calif. healthcare tech start-up that was founded in 2011. In 2021, we were acquired by Edifecs, and our leadership team is largely based with our parent company.

Our company started as a best-in-class Natural Language Processing (NLP) technology and inference platform to analyze vast amounts of unstructured data in order to provide clinical and financial insights. Our NLP engine was developed in close collaboration with Columbia University, whose faculty and staff continues to work closely with Health Fidelity scientists to advance and refine the engine’s accuracy through a supervised machine learning feedback loop.

Today we are focused on helping payer and provider organizations address risk and quality in value-based payment models through our prospective and retrospective solutions.
