Fast, easy healthcare data. Finally.

Particle Health’s modern API platform unifies records from over 270 million patients across the United States. We provide a single, secure access point for the data that digital healthcare companies need to innovate rapidly and at scale.

About us



Our company started in early 2018 with a big vision to break down data silos. Leveraging the opportunities brought forth by new legislation, Co-Founders Troy Bannister and Dan Horbatt built a platform integrated with the largest EMRs in the U.S. By early 2020, the team at Particle Health closed a $12M Series A, led by Menlo Ventures.


Now boosted by significant traction, a growing team roster, legislative landslides, and the heightened awareness of digital-first practices pushed by the realities of COVID-19, Particle Health is leading the charge on developing a best-in-class developer experience, a highly adaptable data transformation pipeline, and building connections with even more critical data sources across the healthcare ecosystem.


Our collective focus has been clear: to build a developer-friendly environment for the biggest innovators in health tech. And the result? We’re quickly dismantling the complexities of traditional healthcare integrations — enabling value-based care companies to get access to the whole (patient) story.

Behind the scenes

Particle uses multiple national networks behind our API. We send the demographics payload out to each network. Network participants receive the payload and attempt to match using their Master Patient Indexes.

The EMRs we connect with must send back the USCDI dataset at a minimum according to interop rules and regulations. This includes everything found in a C-CDA and more (Encounters, Diagnostics, Labs, Medications, Allergies, Procedures, Observations, Vitals, Discharge Notes, etc.).

Before gaining access to patient data

  • It is a requirement for digital health companies to fall under the Treatment Purpose of Use.
  • Our partners also have to be network approved.
  • Customers sign just one BAA.
  • We kick off the process after determining the best use case.
