Clinical documentation, coding, and chart-aware AI workflows
HQ: San Francisco, California, United States | Founded: 2020 | Employees: Not disclosed in the reviewed sources | Stage: $243M Series C July 2025; company reported $343M total September 2025 | Website: https://www.ambiencehealthcare.com/
Mike Ng and Nikhil Buduma co-founded Ambience in 2020. In September 2025 Buduma moved from chief scientist to CEO while Ng became president and chairman. The official leadership release identifies San Francisco HQ, $343M cumulative financing, and integrations with Epic, Oracle Cerner, and athenahealth.
MobiHealthNews reports $243M Series C co-led by Oak HC/FT and a16z, following $70M Series B. The platform supports ambient documentation, summaries, coding, and clinical workflow rather than merely transcription. Its official 2026 news index includes nursing tools, chart-aware inpatient workflows, and Chorus context/action announcements. Healthcare organizations such as Cleveland Clinic and Houston Methodist are publicly named, but clinical outcomes and ROI must be evaluated within their study scope.
Ambience provides ambient documentation, coding, and clinical workflows integrated with health-record systems. It raised $243M Series C in July 2025, then appointed co-founder Nikhil Buduma CEO. Current official news describes 2026 inpatient, nursing, and Chorus expansion; product claims are not a substitute for clinical validation.
Editorial assessment: integrating into care workflows can make documentation AI useful and difficult to replace. Accuracy, clinician review, privacy, billing integrity, and evidence of improved outcomes determine whether platform expansion helps patients rather than only producing more notes.
Evidence boundary: financing announcements establish disclosed transactions, not audited operating performance. Unavailable headcount, margins, and retention are not estimated, and company claims remain attributed.
