Ambience Healthcare vs Knowtex
Knowtex is a prime awardee on a VA ambient scribe contract with a shared ceiling of $775.72M, according to its own September 2026 press release, and says it is live at 79 VA medical centers. Ambience raised a $243M Series C in July 2025, and Cleveland Clinic chose it for five years after a pilot, by the company's own account. Knowtex's funding is reported inconsistently: Tracxn lists $500K from six investors, press mentions backing from Jeff Dean without an amount, and the databases disagree. Knowtex lists twelve EHRs, among them Epic, Oracle Health, Meditech and athenahealth, but integration depth is unstated. It names HIPAA, SOC 2, GDPR, ISO 27001 and FedRAMP without linking audit reports, and its University of Rochester orthopedics pilot is vendor-published. Knowtex takes demo requests with no price, while third parties estimate Ambience at $233 to $417 per provider per month. Knowtex holds a place on the VA contract, so a VA medical center starts there and Ambience is the loser for that buyer. Ambience's documented Epic build carries the private-system side, and Knowtex loses the large private Epic system because its twelve EHRs are listed without integration depth.
