Public company, workplace, funding, and market signals

Updated Aug 2, 2026

Overview

Ambience Healthcare is a privately held healthcare-AI company founded in 2020 that builds an AI operating system for health systems. Its platform automates work before, during, and after encounters—documentation, coding/CDI, referrals, patient summaries, and workflow intelligence—with the stated goals of reducing clinician administrative burden, improving care, and protecting revenue integrity. Public sources conflict on cumulative funding ($343M in the company’s September 2025 announcement versus $345M in subsequent trade coverage; some databases report lower totals because of round-counting differences).

Primary product

Ambience AI Platform: an enterprise clinical-intelligence and workflow suite centered on AutoScribe (ambient clinical documentation), with AutoCDI (coding/CDI), AutoAVS (after-visit summaries), AutoRefer (referrals), chart-aware summaries and pre-visit preparation. It supports outpatient, emergency, and inpatient workflows and 200+ specialties, with integrations including Epic, Oracle Cerner, and athenahealth.

Product & market

Pricing

No public price list or self-serve plan found. Pricing appears to be negotiated enterprise pricing based on health-system size, provider/user count, deployment, and integration scope. Third-party commentary suggests roughly $300–$500+ per provider per month, but this is not company-confirmed and should be treated as an estimate.

Differentiators

—End-to-end platform spanning pre-visit, encounter, and post-visit workflows rather than ambient listening alone
—Real-time, coding-aware documentation with AutoCDI and audit-trail support for revenue-cycle teams
—Deep enterprise EHR integration, including Epic Ambient Module/native FHIR APIs
—Coverage across outpatient, emergency, and inpatient settings and 200+ specialties
—Specialty-specific models and workflows designed for complex health-system environments
—Chart-aware use of longitudinal EHR context
—Reported customer outcomes including lower charting time, increased patient face time, and improved coding/revenue performance
