Chamber Cardio

Chamber Cardio is a Washington, D.C.-based healthcare technology company building a cardiology-focused platform for value-based care. Chamber partners with cardiology practices and health plans to align clinical signals, workflows, and patient data so cardiologists can identify high-risk patients earlier, close gaps against treatment guidelines, and reduce administrative burden. Its workflow-integrated AI surfaces clearer signal from the large volumes of cardiovascular data generated in care, supporting better patient outcomes and financial predictability for payers as cardiology moves beyond fee-for-service. The company supports more than 500 cardiologists across seven states and raised a $60M Series A led by Frist Cressey Ventures, with participation from General Catalyst, AlleyCorp, American Family Ventures, Company Ventures, Optum Ventures, Healthworx Ventures, and Black Opal Ventures. Chamber does not currently publish a public developer API or documentation portal; its platform is built on a FHIR-based data stack (Medplum) with internal REST and GraphQL services.

Chamber Cardio is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Cardiology, Value-Based Care, and Health Tech.

Chamber Cardio’s developer surface includes engineering blog and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
