AIHealthcare

Particle Health is a New York-based healthcare data interoperability company founded in 2018. It provides an API-based platform that aggregates, standardizes, and delivers clinical data and patient medical records for healthcare innovators, including value-based care providers, payers, health systems, and developers. Its Particle Insights Platform is positioned to transform clinical data for care and analytic use cases, including training AI models; however, Particle Health is primarily healthcare data infrastructure/interoperability rather than a standalone clinical AI company. The company states that it connects to all three nationwide health information networks and can provide access to about 90% of EHRs through a single API. Its November 2024 platform announcement stated access to more than 320 million patient records. Particle’s latest clearly verified announced financing is a $25M Series B in July 2022, bringing announced total capital raised at that time to $39.3M. Search results also reference an additional $10M round in January 2025, but an authoritative company announcement was not available in the supplied sources, so it is not included in the estimated funding total.
