Smile Digital Health operates a FHIR®-first Health Data Platform that enables organizations to share structured health data using open standards. The company's technology transforms legacy data into FHIR resources whilst avoiding vendor lock-in, maintaining enterprise performance, and preserving client data ownership.
The platform serves over 120 customers across more than 20 countries, including major payers, legacy health information exchanges, healthcare providers, and research organizations. This breadth of deployment demonstrates the platform's ability to function across different organizational types and geographies within the healthcare ecosystem.
Smile Digital Health was founded by James Agnew and Duncan Weatherston, who met in 2011 while working on health integration and data repository projects. The company describes its team as inclusive, opinionated, and principled, united by a shared mission to improve global health through better data interoperability.
