About
Centaur Labs is a medical data annotation company headquartered in Boston, Massachusetts, founded in 2018 by Erik Duhaime and others. The company has built a platform that produces high-accuracy medical AI training data by aggregating annotations from a curated crowd of medical professionals — physicians, nurses, medical students, and other clinicians — rather than relying on individual expert annotation or general-purpose crowdsourcing. Its core insight is that combining many clinician judgments on ambiguous medical cases produces annotations that are as accurate as (or more accurate than) single expert opinions, while being dramatically faster and more scalable.
Epic holds over 42% of U.S. acute care hospital EHR market share and is embedding AI across 150+ clinical workflows for 2026, while facing antitrust scrutiny.
