About
Ambience Healthcare was founded in 2020 in San Francisco with a mission to eliminate the documentation burden that drives clinician burnout and degrades patient care quality across health systems. The company builds ambient AI documentation technology that listens to clinical encounters across more than 100 medical and surgical specialties, generating accurate, complete clinical notes in the background without requiring clinicians to dictate or type. Ambience's core technology leverages large language models purpose-trained on clinical language, specialty-specific note structures, and electronic health record formatting requirements to produce documentation that is ready for review with minimal editing.\n\nAmbience's platform is deployed across health systems ranging from large academic medical centers to independent practices, covering more than 100 specialties including primary care, surgery, oncology, behavioral health, and pediatrics. Unlike narrower documentation tools that focus on a single specialty or encounter type, Ambience's breadth allows health systems to deploy a single solution enterprise-wide. The platform integrates with major EHR systems including Epic and Cerner, embedding documentation into existing clinical workflows without requiring behavior change from clinicians. Ambience achieved approximately $30 million in annual recurring revenue as of May 2025.\n\nAmbience Healthcare has raised approximately $370 million in total funding, approaching a $1 billion valuation, from investors including Andreessen Horowitz and other leading healthcare-focused venture firms. The company competes with Nuance DAX, Suki, and Nabla in the ambient documentation space but differentiates through its specialty breadth, enterprise EHR integration depth, and strong health system relationships. As health systems face escalating clinician burnout and documentation-driven inefficiency, Ambience's full-enterprise approach positions it as a platform of record for ambient clinical intelligence.
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.
