The Opportunity

Problem

Enterprise healthtech teams face frustration from poor FHIR interoperability between legacy EHR systems and new SaaS platforms, creating data silos that delay patient care.

Solution

FhirProxy acts as a secure, managed proxy that intercepts legacy EHR API calls and translates them to FHIR standards for seamless integration with modern SaaS platforms. Teams configure endpoints once, and it handles real-time data transformation, authentication, and error handling automatically. This eliminates custom coding, reducing integration time from weeks to hours.

Target Audience
