b.well Connected Health Tech Stack

FHIR-based platform unifying fragmented healthcare data and consumer experiences

Hospitals and Health Care Baltimore, Maryland 51–200 employees Founded 2015 Privately Held

b.well builds a FHIR-based data platform designed to consolidate healthcare records and enable care coordination across fragmented systems. The tech stack—Kafka, Spark, DuckDB, FastAPI, MongoDB, Python, and Prefect—reflects a data-engineering-heavy architecture optimized for real-time ingest and transformation at scale. Active projects around data foundations, real-time pipelines, clinical logic engines, and interoperability networks (Carequality, CommonWell, eHealth Exchange, TEFCA) signal a company moving beyond basic EHR integration toward predictive analytics and population health. Hiring has decelerated, with the team weighted toward senior and principal-level data and engineering roles—typical of a company scaling data infrastructure rather than headcount.
