Metriport raises $26M to turn health-data access into clinical answers

Why it matters

Healthcare AI is only as useful as the patient record beneath it. Metriport is using open-source infrastructure, network access and clinical search to own that underlying data layer.

Metriport co-founders Dima Goncharov and Colin Elsinga raised $26 million to expand their healthcare data infrastructure, the San Francisco developer announced on August 27. Matrix led the financing through general partner TJ Parker, with participation from ARTIS and Y Combinator. The round brings Metriport's total disclosed funding to $28.4 million. Metriport did not publish a valuation or identify the round by stage.

Goncharov and Elsinga have known each other since middle school and left engineering jobs in late 2021 to work together. Goncharov had built aerospace and defense systems before working on Amazon Aurora, Amazon Web Services' cloud database service. Elsinga came from consumer health software. That combination shaped Metriport's route into one of healthcare's least glamorous and most durable technical problems: getting a patient's records out of many incompatible systems and turning them into something a clinician can use.

The founders began with a consumer application that tracked sleep, mood, medication, nutrition and exercise. While building it, they ran into the fragmented systems governing health information. They took Metriport through Y Combinator's Summer 2022 batch and redirected the product toward infrastructure, telling TechCrunch in 2022 that the market lacked an open-source way to retrieve and move healthcare data. The original $2.4 million seed financed that transition. The new round is roughly 11 times larger.

From record retrieval to clinical context

Metriport connects to health information exchanges, electronic health record systems, pharmacies, laboratories and admission, discharge and transfer networks. It matches patients, extracts and deduplicates documents, standardizes different formats and converts the resulting information into a unified model based on FHIR, the healthcare data standard.

Customers can receive that data through an API, a warehouse or applications embedded in an electronic health record. Metriport also sells higher-level functions including record search, real-time event alerts, medical record summaries, suspected-condition detection and care-gap identification.

That stack reflects the founders' argument that interoperability has moved beyond connectivity. A provider can technically gain access to a patient's history and still receive hundreds of pages of documents, duplicate records and incompatible fields. The useful product is the answer a clinician needs during an appointment, along with the source material behind it.

At Sollis Health, Chief Medical Officer Scott Braunstein described a patient who arrived with abdominal pain and remembered an old endoscopy without knowing where it had been performed. Sollis used Metriport to locate the operative report, which documented an early ulcer, according to the funding announcement. Braunstein said the record allowed the physician to begin treatment without ordering another CT scan or waiting for a manual records request. The account comes from a Metriport customer and has not been independently measured, though it illustrates the workflow Metriport is selling.

The founders have kept the core code visible. Metriport's public GitHub repository makes that open-source approach concrete, while Metriport operates a hosted, compliant service for healthcare organizations that do not want to run the infrastructure themselves.

Elsinga tied that architecture directly to trust. "The decisions around how patient information is managed and transformed are too important to trust to a black box," he said in the announcement. Open code provides customers with a way to inspect part of the machinery, while Metriport's hosted service still carries the operational burden of access controls, compliance and network governance.

AI needs the record before it can answer the question

Metriport plans to spend the round on engineering, compliance and additional AI, machine-learning and agentic functions. The sequence matters. Clinical agents cannot produce reliable patient context when the underlying record is incomplete, duplicated or trapped in a faxed PDF. Goncharov and Elsinga are positioning Metriport as the retrieval and normalization layer beneath those agents, then moving upward into the interface clinicians use to question a record.

Metriport's homepage says its system can reach records associated with more than 340 million people and processes 4.2 billion network requests each month. It also claims to return a first structured record in less than 15 seconds. Those are Metriport's own infrastructure metrics; the announcement does not provide revenue, pricing, retention or independently verified customer counts.

Named users include Amazon One Medical, Sollis Health and Color Health. Metriport's website also lists Strive Health, Maven Clinic, WeightWatchers, Wellpath, Brightside Health and Canvas Medical among organizations using or featured with the product.

Capital is moving into adjacent parts of the same problem. xCures raised $46 million in June for software that turns fragmented records into decision-ready clinical data. Keebler Health raised $16 million in April for an AI system that extracts evidence from unstructured clinical documentation. Metriport is competing from lower in the stack, combining network access and data normalization with the clinical intelligence built on top.

Trust becomes part of the product

Patient-record access also creates a gatekeeping responsibility. Metriport used the funding announcement to emphasize that its counsel investigates prospective network customers and examines who participates in onboarding calls. That detail lands amid litigation over alleged abuse of national healthcare exchange systems.

A federal complaint filed on January 13 by Epic Systems and several healthcare providers against Health Gorilla and other defendants described an earlier episode involving Metriport. The complaint alleges that RavillaMed entered the Carequality directory through Metriport on August 23, 2024 and pulled 32 records from Epic customers. It says Metriport became suspicious of RavillaMed's purpose and removed the organization from Carequality that same month. Metriport is not named as a defendant in the case, and the allegations against the defendants have not been adjudicated.

The episode shows why compliance work is part of Metriport's technical product. A system capable of finding records across national networks must decide who gets that capability and for what purpose. Faster retrieval increases the value of the service and the damage an abusive user can cause.

Parker brings experience from the customer side of that problem. He co-founded online pharmacy PillPack, later worked on Amazon's healthcare operations and joined Matrix in 2023. Metriport lists him as an investor and adviser. His involvement gives Goncharov and Elsinga a lead backer who has operated inside pharmacy, consumer health and Amazon, rather than a generalist betting on a healthcare API from a distance.

The founders are using the $26 million to turn a record-moving service into the context layer for clinicians and healthcare AI. Their opening came from a consumer app that could not reach the data it needed. Four years later, they are building the infrastructure intended to make that limitation someone else's solved problem.
