What we do

One company, two complementary practices

The same people who consult on FHIR for the largest health systems also build the Sapphire app suite. Each practice feeds the other.

Consulting
Health informatics consulting
Embedded teams working on FHIR implementations, CDS authoring, data quality, terminology, registry modernization, SDOH integration, and AI advisory.
Products
Sapphire® apps
SMART on FHIR apps for chronic care management — Hypertension, Behavioral Health, APCM, and the Periop Opioid Monitor. Built on a shared platform.
How we work

A few things we believe

01
Clinical knowledge first
Healthcare data problems are clinical problems in disguise. Without people who understand the workflow, the model is wrong before the code is written.
02
Embed, don't parachute
We work inside your environment, your repos, your standups. Our average engagement runs longer than 5 years for a reason.
03
Open standards, always
FHIR, CQL, CDS Hooks, US Core, Da Vinci. We co-author the standards we use. No proprietary formats, no lock-in.
