Layer Health

What does the platform offer?

First on the homepage is Clinical Registry Automation. The vendor claims time savings of 50% or more, validated in ten weeks or less, and the health-systems page claims 65% or more across abstracted cases and "better than human performance at complex chart abstraction". Custom quality-metric abstraction covers variables from surgical site infection to discharge medication, the vendor says.

A clinical guidance line adds Clinical Pathways, which finds patients eligible for guideline-aligned care, and Site of Care Optimization, which screens low-acuity cases against protocols. The vendor says validation runs on each customer's own data before go-live.

Who sells it and who uses it?

David Sontag, PhD is CEO and on leave as an MIT professor. Divya Gopinath and Luke Murray co-head engineering. The vendor names Define Ventures, GV, Flare Capital Partners and MultiCare among its investors, and a June 2025 release announced a strategic investment from Intermountain Ventures of an undisclosed amount.

Intermountain Health has a multi-year deployment across 33 hospitals in stroke, bariatric and cardiovascular registries, the vendor says. White Plains Hospital is named in a May 2025 release. A Froedtert nurse abstractor quoted on the vendor's site says "I couldn't imagine going back to our old way of doing things."

Is any of the evidence independent?

No published evaluation of the product exists. The papers with Layer Health affiliations, including a July 2026 npj Digital Medicine paper on language models as EHR encoders with Sontag as co-author, are the team's research and do not test the platform. The homepage's "200+ peer-reviewed publications" counts the team's work in the same way.

What does the site say about EHRs and compliance?

It says the platform integrates natively into clinical workflows and names no EHR. The footer reads "Enterprise-grade security and compliance". Calls to action are "Schedule a Demo", "Get in Touch" and "Book a call".

The verdict

A quality department abstracting registries by hand is the work Layer Health targets, and Intermountain's 33 hospitals is the largest deployment the vendor cites. A department weighing it would be taking the "better than human" claim from the vendor, with validation run on its own data.
