Who we are

Particle is shaping the new standard for healthcare data exchange with a user-friendly API platform. We create intuitive experiences for developers, build scalable infrastructure product teams love, and collaborate with innovative leaders launching data-driven solutions.


Fast, easy healthcare data. Finally.

Particle Health’s modern API platform unifies records from over 320 million patients across the United States. We provide a single, secure access point serving as the pipes for these medical records via direct integrations with the largest healthcare networks and frameworks, including CommonWell, CareQuality and eHealth Exchange. 

About us


The backstory

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, and in the summer of 2022 we raised a $25 million Series B, led by Canvas Ventures. 


Now boosted by significant traction, a growing team roster, legislative landslides, and the heightened awareness of anti-information blocking and compliance, Particle Health is leading the charge on developing a best-in-class interoperability platform that aggregates and delivers actionable patient data and insights to companies. 

Insights driven

The future of healthcare is all about data-driven optimization and Particle provides the clean, interoperable data needed to derive breakthrough insights that’ll create the next big product in healthcare. By searching the nation’s most comprehensive networks, we can pinpoint the relevant data companies need to make clinical decisions, and pull curated, focused data outputs directly into their EMR or platform.

How does this actually work?


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.
