About

Metriport is an open-source healthcare data platform that provides a universal API for accessing and exchanging patient medical records. The company connects to the largest clinical data networks in the US — including CommonWell Health Alliance and Carequality — giving digital health companies access to comprehensive medical data for over 300 million patients through a single integration. Metriport's FHIR-native Medical API retrieves, standardizes, consolidates, and deduplicates clinical data from thousands of sources including HIEs, EHRs, pharmacies, and labs, delivering it in formats like FHIR R4, C-CDA, and PDF. The platform also offers AI-powered clinical summaries and a no-code Provider Dashboard. Founded in 2021 by Dima Goncharov and Colin Elsinga — software engineers who had known each other for over 15 years — the company went through Y Combinator S22 and raised a $2.4M seed round. As the world's first open-source platform of its kind, Metriport emphasizes transparency, self-hosting capability, and developer experience over proprietary lock-in.

DailyDropout Take

Metriport caught our attention as the open-source challenger in a healthcare data market dominated by expensive, proprietary gatekeepers. With two engineers who'd known each other for 15 years and a YC S22 pedigree, they built what TechCrunch called 'Plaid for healthcare' — a universal API that makes accessing patient medical records as simple as a few lines of code. In an industry where data fragmentation costs billions and kills innovation, betting on open-source transparency felt like the right side of history.

What Makes Them Unique

Metriport is the world's first open-source healthcare data API, offering full transparency and self-hosting capability while connecting to all major US clinical data networks. This open-source approach provides unmatched developer experience and eliminates proprietary lock-in — a critical differentiator in an industry dominated by closed, expensive incumbents.
