The company provides a unified API layer enabling access to more than 320 million patients' medical records from over 160,000 healthcare organizations, delivered as structured FHIR R4 data.

Founded in 2018 by Troy Bannister and Dan Horbatt, with Jason Prestinario serving as CEO since May 2023, Particle Health serves value-based care organizations, health systems, payers, and healthcare developers seeking to act on real-time clinical data.

The platform functions as a middleware layer between EHR systems (including Epic) and healthcare companies, standardizing and unifying healthcare records from thousands of sources.
