What Particle Health does
Particle Health operates an API-first healthcare data interoperability platform that aggregates, normalizes, and contextualizes clinical records from 320+ million patients across 160,000+ healthcare organizations. The platform connects to all three major US Health Information Networks — Carequality, CommonWell Health Alliance (as a QHIN), and eHealth Exchange — via a single RESTful API, supporting FHIR R4 and C-CDA standards alongside a proprietary tabular format. Core modules include the Particle Insights Platform, Particle Snapshot (AI-powered clinical summarization), Particle Signal (nationwide care transition alerts), Particle Workbench (analytics), Particle Navigator (patient journey monitoring), Specialty Search across seven condition areas, ADT feeds, FOCUS pre-curated specialty datasets, Medication Reconciliation, and TEFCA in a Box. A proprietary Record Locator Service and patient identity linking engine differentiate Particle from raw HIN access by locating approximately 90% of patients nationally and deduplicating records across fragmented data sources.
The company's commercial model is a hybrid product-led growth and enterprise sales motion: a free developer portal enables self-service API trials, while enterprise customers (payers, health systems, value-based care providers, and digital health platforms) move through quote-based annual subscriptions with a stated contract-to-value time of under 12 weeks. Particle also distributes via OEM/embedded channels (Particle for Platforms and Particle for EHRs), reaching customers such as One Medical, Reveleer, Azalea Health, Jasper Health, Yuvo Health, Triangle Health, xCures, Cureatr, LifeMD, and Hona across telehealth, oncology, community health, rural health, AI health navigation, and medication management segments. Revenue is not publicly disclosed; the company has raised approximately $49.3M across disclosed rounds (2018–2024), with a $25M Series B led by Canvas Prime in 2022 and a $10M insider extension in December 2024.
Operationally, Particle has been an active participant in healthcare interoperability policy — engaging with CMS on TEFCA enforcement and anti-information blocking — and in September 2024 filed an antitrust lawsuit against Epic Systems alleging data blocking, which survived a motion to dismiss in 2025. Leadership transitioned in May 2023 when Jason Prestinario (ex-Komodo Health, ex-Palantir) became CEO, with founder Troy Bannister moving to Founder/CSO. The company maintains HITRUST i1, SOC 2, and HIPAA certifications, serves a domestic US market, and operates with a headcount in the 11–50 range.

Particle Health competitors and assessment
Company assessmentDirect peers
- Health Gorilla: Health Gorilla is a Qualified Health Information Network (QHIN) and clinical data exchange platform serving payers, providers, and digital health companies. It is one of Particle's closest direct competitors, operating a similar interoperability/API model connecting to national HINs and selling into overlapping payer and digital health customer segments.
- Redox: Redox is a healthcare API integration platform that allows digital health vendors to connect with hundreds of EHR systems through a single integration. Like Particle, it competes on developer experience and 'one API for healthcare,' targeting digital health developers, payers, and providers with API-first interoperability.
- 1upHealth: 1upHealth is a FHIR-native health data platform offering patient-mediated data exchange, payer-to-provider APIs, and bulk data export. It directly overlaps with Particle's FHIR R4, patient-mediated exchange, and value-based care data aggregation use cases.
- Datavant: Datavant operates a health data connectivity and de-identification platform that links patient records across providers, payers, and life sciences. It competes with Particle in clinical-data aggregation and longitudinal record linking, particularly for payer and life sciences customers.
- Seqster: Seqster is a patient-centric health data interoperability platform that aggregates EHR, genetic, and wearable data via a single API. It overlaps with Particle's patient-mediated exchange positioning and serves pharma, providers, and digital health companies.
- Smile CDR: Smile CDR provides a FHIR-based clinical data repository and interoperability platform used by health systems, governments, and digital health companies. It competes with Particle in the FHIR data infrastructure layer, particularly for organizations needing on-premise or self-hosted data stores.
Emerging players
- Avaneer Health: Avaneer Health is a blockchain-enabled healthcare data exchange network launched by a consortium of payers and providers. It overlaps with Particle's payer-provider data exchange value proposition, but focuses on direct payer-provider connectivity rather than developer-mediated API access.
- Zus Health: Zus Health offers a connected health data platform that aggregates patient records and provides a shared clinical data layer for digital health builders. It is comparable to Particle in serving developer-led digital health companies with longitudinal patient data.
Broad incumbents
- Komodo Health: Komodo Health is a healthcare intelligence platform providing patient-level data and analytics primarily to life sciences and payers. Particle's CEO Jason Prestinario previously led Komodo's payer/provider expansion, and the two compete for healthcare data buyers, though Komodo focuses more on analytics than on raw API exchange.
- Veradigm (formerly Allscripts): Veradigm is a large EHR and health IT vendor with data exchange capabilities and FollowMyHealth patient-mediated exchange. As a broader incumbent with overlapping interoperability capabilities and a large installed provider base, it competes for health system interoperability business that Particle addresses.
