Ambience Healthcare has raised $243 million in Series C funding at a valuation of more than $1.25 billion, making it one of the most heavily funded startups in the emerging category of ambient AI for clinical operations. The round, co-led by Oak HC/FT and Andreessen Horowitz, with participation from the OpenAI Startup Fund, Kleiner Perkins, and Optum Ventures, reflects growing investor interest in AI systems designed to automate documentation, coding, and administrative workflows across healthcare settings. Rather than focusing on standalone tools, Ambience has developed a platform intended to integrate directly into electronic health records and support clinicians across high-complexity specialties, inpatient settings, and emergency departments, areas often overlooked by early AI deployments.
Founded in 2020, Ambience has grown into what it describes as an end-to-end ambient AI platform, integrating with electronic health record (EHR) systems to automate documentation, clinical coding, and revenue cycle workflows in real time. Already deployed in institutions like Cleveland Clinic, UCSF Health, Houston Methodist, and Memorial Hermann, Ambience is used across over 100 ambulatory subspecialties and high-pressure settings like emergency departments and inpatient care, precisely where documentation burdens are heaviest.
Ambience CEO and co-founder Mike Ng believes this funding validates the company’s broader platform strategy. “We’ve developed a best-in-class platform that, in practice, does a few important things,” Ng said. “Before the patient even walks into the room, the system summarizes all relevant context for the clinician. During the visit, it listens in the background and automatically generates documentation. After the visit, it automates downstream workflows like billing, prior authorization, and coding.”
