Metriport
An open source platform that pulls a patient’s scattered records out of the national health information networks and returns them as one structured file. It announced $26 million in August 2026. The public record shows what it can reach, and what it must promise to reach it.
The finding nobody could name
A patient arrives at a Sollis Health clinic with pain under the ribs. He knows he had an endoscopy. He does not know what it found, or who did it.
In the ordinary version the clinic orders a CT scan, or faxes a request into the dark and waits. In the version Sollis described in Metriport’s August 2026 funding release, the clinic ran a query and the old operative report came back, showing an early ulcer. Treatment started that day.
A chief medical officer told that story in a press release, so it is the company’s account of its own product, and has not been independently measured. What can be checked is the plumbing underneath, and the permission slip that makes it legal.
Why the record is somewhere else
Records in the United States sit where care happened. A clinic in Texas, a hospital in California, a pharmacy, a lab. For two decades the fix has been networks rather than one database: Carequality, CommonWell and eHealth Exchange, and since December 2023 the federal TEFCA framework and its designated Qualified Health Information Networks.
Those networks are not open highways. Every participant attests to a permitted purpose, and the one answered automatically and in real time is Treatment. That single word is the gate, and 2024 showed how much weight it carries.
In October 2024 Carequality closed the first dispute resolution process in its ten year history, between Epic and Particle Health. The panel found two Particle customers had submitted queries not intended for treatment purposes in at least some instances, and barred them for twelve months. Particle accepted a six month corrective action plan covering onboarding diligence. Epic agreed to publish clear, objective criteria for judging whether a participant is performing treatment.
Two engineers and a tracking app
Dima Goncharov finished a two year Computer Systems Technology diploma at BCIT in Vancouver in 2015, worked on satellites at MDA, then moved to Amazon Web Services. Colin Elsinga came from consumer health software. They had known each other more than fifteen years. In 2021 they quit.
The first Metriport, short for metrics portal, was a personal tracking app built in twelve weeks and launched in January 2022. It got them an interview at Y Combinator, which they went into feeling like imposters, and a place in the Summer 2022 batch. Talking to American healthcare companies during that batch redirected them.
Wearables first, then the networks
The first product, shipped in December 2022, was a Health Devices API for wearables, announced alongside a $2.4 million seed at a $20 million valuation, all on post-money SAFEs. The harder product followed. CommonWell published a member Q and A with both founders in July 2023. Carequality has carried an implementer page for Metriport dated September 12, 2023, the month the Medical API launched publicly. In a later post citing the February 2024 Change Healthcare outage, the company said Carequality would become a direct connection rather than a second hop.
By August 2026 it was naming Amazon One Medical, Sollis Health and Color Health as users, and raised $26 million led by TJ Parker of Matrix, a co-founder of PillPack.
What is proven, and what is still claimed
| Evidence | What the record shows | Source type |
|---|---|---|
| Carequality | Carequality hosts an implementer page for Metriport dated Sep 12, 2023, and Epic’s January 2026 federal complaint calls Metriport a Carequality implementer. | Public record |
| CommonWell | Listed under Service Adopters on the CommonWell members page, checked Sep 23, 2026, alongside Oracle Cerner and Redox. Member Q and A published Jul 25, 2023. CommonWell was designated a QHIN in February 2024. | Public record |
| TEFCA status | Metriport does not appear on the Sequoia Project’s designated QHIN list, checked Sep 23, 2026. Its README says one query reaches TEFCA and its QHINs, Carequality, CommonWell and eHealth Exchange. It reaches TEFCA through a QHIN, not as one. | Public record |
| Permitted purpose | The API page states that production access needs a covered entity, an NPI, and a Treatment purpose of use, and the sandbox needs none of them. In 2023 it told Fierce Healthcare its customers were only those authorized for treatment purposes. | Company-stated |
| Named in Epic’s 2026 complaint | Epic, OCHIN, Reid Health, Trinity Health and UMass Memorial Health sued Health Gorilla and several data companies on Jan 13, 2026. Reporting on the filing says RavillaMed joined Carequality in August 2024 through Metriport, pulled 32 records, then was removed after Metriport grew suspicious. Metriport is not a defendant; the allegations are unadjudicated. | Independent |
| Public code, licence | Created Dec 21, 2022, TypeScript, 784 stars, 113 forks, 22 contributors. AGPLv3, with a carve-out: everything under the pkgs directory is an Enterprise Edition under a separate licence. GitHub’s detector reports the licence as Other. | Public record |
| Public code, cadence | Last substantive public commit Oct 30, 2025. Zero commits from Nov 1, 2025 to Aug 1, 2026. Eight commits on Aug 27 and 28, 2026, one titled chore: update public repo, from a branch named eng-1444-public-sync, on the day of the funding announcement. Last release tag v5.84.0, Mar 27, 2024. The npm SDK shipped 18.21.0 on Sep 23, 2026. | Public record |
| Certification | SOC 2 Type 2 and HIPAA per an archived 2024 security page, with Oneleet for compliance monitoring. HITRUST r2 announced Aug 27, 2026. No independent listing found. | Company-stated |
| Scale figures | 340 million individuals reachable, 4.2 billion network requests a month, first structured record in under 15 seconds, 96% average match rate. Older company text says 300 million. No revenue or pricing disclosed. | Company-stated |
| Round stage | The release calls it new funding and gives no valuation and no stage. Trade coverage the same day calls it Series A. | Differs by source |
| SEC filings | No company named Metriport in EDGAR, and full text search returns zero documents mentioning it across all form types. | Not found |
Read plainly: the network position is real and checkable, and narrower than the marketing shorthand. Metriport is an implementer on Carequality and a Service Adopter on CommonWell, which is not the same as being a QHIN, and production access is scoped to Treatment. The open source claim is narrower too. The licence is AGPLv3 with an enterprise carve-out, and the public repository is fed in occasional syncs, with a ten month silence that ended on the morning of the funding announcement while the SDK kept shipping. Neither fact contradicts the product. Both change what a customer inspects when they read the code.
What to watch
- Whether the public repository resumes a regular cadence, or the August 2026 sync stays an exception.
- Discovery in Epic v Health Gorilla, which turns on how implementers vet the organizations they list in the directory.
- Whether Metriport pursues purposes beyond Treatment as TEFCA adds exchange purposes.
- Independent confirmation of HITRUST r2, and third party measurement of the match rate and latency figures.
- A Form D for the August 2026 round, or continued silence in EDGAR.
In their words
“One major issue that exists in the U.S. today is the fact that many individuals still aren’t able to access their own medical data, largely due to gatekeeping by hospitals and other medical providers.”
Colin Elsinga, co-founder and COO, TechCrunch, 2022 · Independent
“The exchange of information is most likely happening via a fax machine right now, and it causes serious delays for patients to be treated.”
Dima Goncharov, co-founder and CEO, BCIT alumni profile, 2023 · Interview
“When we set out to build our Medical API, joining CommonWell was our number one priority, considering the size and value the network brings.”
Metriport founders, CommonWell member Q and A, July 2023 · Alliance
“We want to make sure we empower startup-size companies looking to grow and innovate in the space and not price gouge them.”
Dima Goncharov, Fierce Healthcare, October 2023 · Independent
“We do deep diligence on every organization that wants to access the healthcare exchange data networks via Metriport.”
Matt Davis-Ratner, general counsel, August 2026 release · Company release
“We created Metriport with open source code because the decisions around how patient information is managed and transformed are too important to trust to a black box.”
Colin Elsinga, August 2026 release · Company release
“I see dozens of consumer health companies every year, and the best ones are increasingly working with Metriport.”
TJ Parker, general partner, Matrix, August 2026 release · Investor
“Through Metriport, we found the exact operative report, showing an early ulcer.”
Dr. Scott Braunstein, chief medical officer, Sollis Health, August 2026 release · Customer
