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.
