VA Awards Nationwide Ambient AI Scribe Contract to Knowtex and Abridge
In October 2025, the U.S. Department of Veterans Affairs selected two ambient AI scribe vendors, Knowtex and Abridge, to deploy voice-driven clinical documentation tools across the Veterans Health Administration, the largest integrated healthcare system in the country. The award came through the VA's competitive AI Tech Sprint for Ambient Scribe, an evaluation that screened more than 150 candidate solutions before narrowing the field.
The scope of the contract puts a generation of healthcare AI inside the room where roughly 9.1 million veterans get their care. VHA operates 170 medical centers and 1,193 outpatient clinics, a footprint that makes it one of the few U.S. institutions big enough to test ambient AI at population scale rather than at single-site pilot depth. Knowtex's award carries a $15 million contract value, per the company's October 2025 release, and positions the San Francisco startup alongside an incumbent-adjacent competitor with a parallel pathway into the same clinical workflow.
The selection sits inside a multi-year VA push to adopt AI under formal guardrails. CTO and Chief AI Officer Charles Worthington has framed the agency's "strategic vision" as making VA "a leader in AI, providing faster services, higher quality care, and more cost-effective operations." The Tech Sprint is the procurement vehicle for that vision: an open competition that let the VA compare vendors head-to-head rather than buy through a single-source negotiation. Knowtex was a top-3 winner in the 2024 cohort of that sprint before its October selection into the deployment cohort.
Knowtex itself is an unusual profile for a federal prime contractor. Founded in 2022 by Caroline Zhang and Jocelyn Kang, the company is led by Stanford AI scientists, headquartered in San Francisco, and backed by Y Combinator, AWS, the UCSF Rosenman Institute, and MedTech Innovators. Most of the VA's largest health-IT contracts go to firms with decades of federal experience; the Tech Sprint route gives newer entrants a defensible path in, provided their technology clears the evaluation bar. Zhang has framed the company's role in plain terms: "Documentation burden is the tax clinicians pay for every visit, and it is the single clearest thing technology can give back."
Abridge arrived at the same deployment through a parallel track. The VA's Strategic Acquisition Center Frederick, acting on behalf of the Veterans Health Administration's Digital Health Office, signaled intent to award firm-fixed-price contracts to Nuance Communications and Abridge, winners of the AI Tech Sprint for Documenting VA, within 60 days of public notice. Abridge now runs at multiple pilot sites, including the Prescott VA clinic, where the system produces raw transcripts and machine-generated summaries that clinicians must review and approve before the notes enter a patient's chart.
The practical consequence of two vendors in parallel is a deliberate one. VA officials have said the dual-track deployment lets the department compare vendors, workflows, and clinician satisfaction side by side before selecting a long-term enterprise solution. That comparison is already producing operational data: at the Prescott site, 10 or more VA facilities are participating in the pilot, and the Phoenix VA Medical Center is preparing its own rollout. The two-vendor posture turns the deployment into an evaluation rather than a procurement, and it gives the VA leverage to push both companies on the integration work the next phases of this rollout will demand.
The contract's scope (170 medical centers, 1,193 outpatient clinics, 9.1 million veterans) is also what makes it a federal-health precedent rather than a single-agency story. If the deployment holds, other agencies running their own burnout-reduction mandates will be watching the metrics it produces.
Early Pilot Data Shows Clinicians Saving 1–2 Hours Daily
The clearest signal out of the VA's ambient scribe rollout comes from the Kansas City VA Medical Center, where 18 primary care providers ran a 90-day evaluation of Knowtex's tool integrated directly into CPRS. Every one of the 18 participants wanted to keep using the system after the trial ended, and most reported saving one to two hours of after-hours documentation per day. Before the tool, providers at the site were spending anywhere from 15 minutes to over an hour per visit finishing notes after clinic — the so-called "pajama time" that has become one of the leading drivers of burnout in American medicine (news.va.gov).
The emotional weight of that recovery shows up in the clinician comments. One Kansas City provider told the VA: "Today was the first time I have been able to complete my notes and go home on time since I started working at VA 10 years ago." Another called the tool "the first [that] allowed me to both reduce administrative work and improve my interaction and relationships with patients." A third described the shift in practical terms: "I am able to sign off on my notes sooner and able to capture a lot more of what occurred during the visit." A fourth noted that "ambient scribe has enhanced my patient visits as I can be more focused on my interaction with the Veteran," citing more eye contact, more time talking, and more bandwidth to consult reference tools like UpToDate while the patient speaks (news.va.gov).
The patient side moved in the same direction. Veterans surveyed after visits with the ambient scribe reported a 95.8% satisfaction rate on feeling carefully listened to, an almost three-point jump from the pre-evaluation baseline. Across every other satisfaction measure (providers explaining things understandably, knowing post-visit next steps, feeling respected and comfortable, trusting Kansas City VA Primary Care for their health care needs) the shift ran in a narrow band of roughly two to three points (news.va.gov). That pattern tracks the clinical literature: a JAMA quality improvement study of 263 physicians and advanced practice practitioners across six health systems found that after 30 days with an ambient AI scribe, clinicians reported decreased documentation burden, less time spent charting outside clinical hours, reduced burnout risk, and increased job satisfaction (jamanetwork.com).
The company also stresses that its system is not pure voice-to-text: it generates medical notes, coding suggestions, and order capabilities, translating the patient story into structured documentation and next steps (abc15.com). That specialty-aware design matters in a federal system where clinicians work across primary care, oncology, mental health, and orthopedics, each with its own documentation requirements.
Pilot data is not finished settling. The VA is still running ambient scribes from both Knowtex and Abridge across at least 10 sites, including Prescott, Arizona, and officials say cost-savings and workload-reduction analyses are still underway (abc15.com). Providers have flagged friction points that could blunt the gains: smoother CPRS integration, easier handling of reminders and orders, more flexibility to tailor note style, and less mental load from splitting focus between patient and screen (news.va.gov). A June 2026 VA Office of Inspector General report cautioned that generative AI tools used without proper oversight can create patient-safety and data-privacy risks, though the same report noted that formal ambient scribe deployments appeared to carry stronger guardrails than ad-hoc internal use.
Knowtex Scales Support Infrastructure From 7,500 to 80,000 VA Users in 90 Days
The same contract that put Knowtex into CPRS at the Kansas City VA in October 2025 has now forced the company into a logistics problem few health-AI startups have ever faced. A Knowtex job posting dated September 2026 describes a "critical growth phase: scaling from 7,500 to 80,000 users over the next 90 days, with plans to reach 150,000 users within 3 years," a roughly tenfold jump in three months, and a twentyfold jump over three years. Built In's profile of Knowtex lists 12 employees.
Building the support apparatus for 80,000 clinicians inside the VA, the largest integrated health system in the country, is not a feature update; it is a company-rewriting program of work. The infrastructure list is unusually explicit because Knowtex is hiring publicly for it. The new Customer Support Program Manager role, advertised on Built In and The Ladders, lists "Core operational framework: ticketing workflows, metrics dashboards" among the first responsibilities, and demands "proficiency with ticketing platforms (Pylon, Zendesk, ServiceNow, Jira Service Desk) or demonstrated ability to evaluate, select, and implement support technologies." The job reports to the Director of Customer Delivery, supervises Customer Support Specialists directly, and carries up to 20% travel for VA site visits, training events, and quarterly team meetings. The language is corporate, but the stakes are operational: at 7,500 users a Slack channel and a shared inbox can absorb support volume; at 80,000 they cannot. Ticketing has to become a tiered system, dashboards have to expose real-time latency and error rates, and escalation paths have to be defined for the specific failure modes of an ambient scribe: dropped encounters, misattributed speakers, hallucinated orders, CPRS sync failures.
The performance bar Knowtex is writing into the role is concrete. The listing commits to "99.5%+ system uptime maintained through rapid technical issue detection and coordinated response" within six months, and a "Support program scaled to 100,000+ users with sustained quality metrics" within a year, followed by "scalable technical processes and documentation enabling continued growth to 150,000 users" (builtin.com). A Glassdoor mirror of the same posting describes the goal more bluntly: "Support program infrastructure established to scale from 7,500 to 80,000 users without quality degradation." The repetition is the point: the recruiting page is essentially a public build plan.
The support build is downstream of a deployment curve that has already moved fast. Knowtex went live at Kansas City in October 2025 as the first ambient scribe fully integrated into CPRS. Four more sites (Dallas, Miami, Loma Linda, and East Orange) came online in January 2026, and in February 2026 Knowtex received green light for nationwide primary care, hitting a national go-live across 10 Veterans Integrated Service Networks (VISNs) and 79 VA medical center locations. The Kansas City evaluation, a 90-day review of 18 primary care providers, found that every participant wanted to keep the tool. That result is the engine pulling the support org forward: every additional hour per clinician saved is also an additional clinician who can file a ticket when the scribe misfires.
The contract structure sets the pace Knowtex has to match. The $15 million award, announced in October 2025, followed a competitive evaluation of more than 150 solutions in the same sprint. The Veterans Health Administration operates 170 medical centers and 1,193 outpatient clinics serving more than 9.1 million veterans, the full addressable footprint that the 150,000-user target implies. The support organization is what makes the tax break durable: a scribe that drops notes in the first week at a new site will be turned off in the second, and a 20,000-clinician rollout will be the thing that gets compared in the next oversight hearing.
Competitors Abridge and Nuance Diverge on EHR Integration Paths
The VA's ambient scribe story starts with two companies, not one. In July 2024, the Department of Veterans Affairs named Abridge and Nuance Communications as winners of its AI Tech Sprint, with each vendor cleared to receive a sole-source contract for piloting ambient dictation technology inside VA facilities. The sprint itself drew more than 150 competing teams across its two tracks: ambient dictation for clinical encounters and community care document processing, and awarded a first-place purse of $300,000 per track.
The contract pathway diverged quickly after that. By June 23, 2025, the same center had finalized Definitive Contract 36C10G25C0011 with Abridge, a fixed-price award for a Commercial-Off-the-Shelf, cloud-hosted ambient dictation solution worth up to $14.98 million, running across a base period plus four option periods out to a maximum 36-month period of performance. A separate sole-source award to Abridge on June 23, 2025 carried a value of $5,369,500 for the underlying COTS ambient scribe product (highergov.com). Knowtex then replaced Nuance for the national deployment slot, a fact confirmed by VA Assistant Under Secretary for Health Carolyn Clancy, M.D., when she told the Digital Medicine Society's Healthcare 2030 event in September 2025 that the agency would roll out Abridge and Knowtex, not Abridge and Nuance, "next month" (fiercehealthcare.com). Nuance, the long-standing Epic partner that had built out its ambient documentation products around Microsoft Azure and Epic integration, never converted its Tech Sprint win into a final VA award for this rollout.
The EHR integration question is what separates these vendors from each other and from Knowtex. The VA's June 2025 solicitation language specified that "providers can initiate encounter recording without manual entry of patient identifying information, and draft notes can be automatically inserted into the electronic health record without copy and paste manual effort" (fiercehealthcare.com). For Knowtex, that meant a direct, live connection into CPRS at the Kansas City VA Medical Center by October 2025. Abridge, by contrast, had been built from the ground up around Epic, the platform that dominates large U.S. health systems but is only now beginning its long-delayed VA deployment under the agency's restarted Electronic Health Record Modernization program.
That mismatch maps onto the two vendors' commercial footprints. As of June 2025, Abridge reported deployment in more than 150 health systems, plans to support more than 50 million medical conversations during 2025, and a proprietary dataset derived from more than 1.5 million medical encounters. The company's Series E in June raised $300 million led by Andreessen Horowitz with Khosla Ventures, lifting its reported valuation to $5.3 billion just four months after a $250 million Series D (fiercehealthcare.com). Nuance, owned by Microsoft since 2021, had been advancing ambient documentation through its Epic partnership rather than as a standalone product.
The contract notices make plain why CPRS-native integration mattered enough to keep both Abridge and Knowtex in the rollout. Federal acquisition officers required that the ambient scribe solution be FedRAMP-authorized, run in a VA-approved cloud, and write notes back into the agency's own EHR without forcing clinicians to copy-paste between windows. VA's CTO put the awkwardness plainly to the press in 2024: "I feel like right now, we're in that awkward stage where most of these tools are a different window … where there's a lot of flipping back and forth between tools" (fedscoop.com). Eliminating that window-to-window friction inside CPRS is the technical claim Knowtex made when it branded itself "the first Ambient AI scribe to be fully integrated into CPRS."
The result is a two-vendor national deployment in which CPRS-native integration is the technical discriminator, not ambient transcription quality. Abridge brings Epic-era scale, the 1.5-million-encounter dataset, and $5.3-billion-valuation backing; Knowtex brings a CPRS-first architecture, specialty-trained models, and a reported track record of going live with primary care at 79 VA Medical Center locations across 10 VISNs by February 2026. Nuance sits outside the deployment entirely, having been dropped from the second slot. The wider federal push for seamless EHR-compatible ambient AI now runs through whatever the VA proves out at CPRS, a precedent other agencies, including HHS and the DoD, will inherit.
Why a Tech Sprint, Not a Procurement, Drives Federal Burnout Strategy
The VA's ambient AI scribe story starts not with a procurement notice but with a competition, and the competition itself reveals how the federal government is now treating clinician burnout as a solvable engineering problem.
On October 31, 2023, the Department of Veterans Affairs launched its AI Tech Sprint with a stated mission that tied technology adoption directly to workforce health. Under Secretary for Health Shereef Elnahal framed it bluntly: "AI solutions can help us reduce the time that clinicians spend on non-clinical work, which will get our teams doing more of what they love most: caring for Veterans" (news.va.gov). The sprint ran two tracks: speech-to-text for medical appointments, and document processing to integrate non-VA records into VA charts, with $1 million in total prize money: $300,000 for first place, $150,000 for second, $50,000 for third in both categories.
The funnel was deliberately wide. VA received more than 200 applications, narrowed to 100 teams, then to 60 participants for the output challenge. From an initial pool of 152 teams, the agency ultimately named 10 winners (news.va.gov). The finalists on the ambient scribe track read like a market map of the entire sector: Abridge, Althea Health, ARETUM, Cognosante, Commure, Contrast AI, Credence, DeepScribe, TranscribeMD AI (Juan T. Garcia), Knowtex, Nuance, QuantumTechIT, Sourceree, Tali AI, and Veterans EZ Info. The document-processing finalists included Abstractive Health, Booz Allen Hamilton, Instabase, Palantir, and Wired Informatics, a mix of startups, contractors, and prime defense integrators that signaled how seriously the federal ecosystem was taking the problem.
The sprint was framed as one piece of a wider push. VA pointed to its earlier REBOOT initiative (Reduce Employee Burnout and Optimize Organizational Thriving) and reported a 20% drop in VHA turnover from 2022 to 2023 as evidence that structured intervention works. The Tech Sprint added an AI-specific lever. Charles Worthington, VA's CTO and Chief AI Officer, later told GovCIO Media & Research that the sprints were part of a larger strategy to "prepare the workforce to adopt AI," with one of four internal AI work streams dedicated to workforce readiness (govciomedia.com).
That competitive structure has paid direct operational dividends. Knowtex was a top-3 winner of the 2024 AI Tech Sprint for Ambient Scribe before securing its October 2025 national deployment award; Abridge and Nuance Communications won parallel VA contract awards through the same sprint pathway. By separating the competition from the procurement, VA created a funnel where clinical validation preceded scale-up, a deliberate inversion of the usual federal buying pattern.
The bigger story sits in the diffusion beyond VA. The Tech Sprint approach has become a template. HHS expanded AI use cases across federal health agencies in the period that followed, and CMS leadership framed the agency's 2026–2031 Strategic Framework as positioning CMS as an "AI first" organization. DoD health systems, running their own clinician burnout challenges inside the Military Health System, are watching the VA rollouts as proof that ambient scribe can survive CPRS integration, federal security review (Authority to Operate, zero-trust architecture, high-impact AI monitoring under OMB-M-25-1), and deployment at scale.
The connecting tissue across all of these initiatives is the framing: clinician burnout as the wedge, ambient AI as the tool, and competitive procurement as the mechanism. The VA's Tech Sprint did not invent ambient scribe, but it turned federal adoption from a slow acquisition into a documented sprint, and that pattern is now spreading to HHS, CMS, and DoD.
Market Forecast and DoD Expansion Point to Continued Federal Growth
Market analysts are sizing the federal ambient scribe opportunity alongside a much larger commercial wave, and both arcs point up. The U.S. ambient clinical documentation AI market was valued at roughly $1 billion in 2025 and is projected to reach about $3.1 billion by 2030, expanding at a compound annual growth rate of around 25% (virtuemarketresearch.com). Adjacent forecasts bracket that figure:
| Segment | 2025 | 2030 | CAGR |
|---|---|---|---|
| U.S. AI-powered clinical documentation | $4.01B | $13.99B | 28.3% |
| Generative-AI clinical documentation (subset) | $0.83B | $3.6B | 34.1% |

Hospitals and health systems already hold 58.7% of end-user revenue in 2025, and software commands about 58.4% of global revenues (evolvancemarketresearch.com, dataintelo.com), a mix that maps neatly onto the federal buyer profile.
Knowtex has framed its rollout as a proof point rather than an endpoint. The company reached a nationwide VA production go-live in February 2026, bringing ambient scribe support to primary care documentation across 10 VISNs and 79 VA medical center locations, and management has telegraphed a three-year ramp toward 150,000 users, a figure that would make this one of the largest healthcare AI implementations in the country (prnewswire.com). The economics of that scale-up are unusually clean. One analyst working paper estimates that a physician who saves two minutes per note across 20 daily visits recaptures 40 minutes of clinical time per day; redirected toward additional visits at roughly $85 of net revenue each, that generates more than $100,000 in annual upside per physician against platform costs in the $4,000–$7,200 range, a 14 to 25x first-year return (evolvancemarketresearch.com). Boston Children's Hospital and Ochsner Health have publicly documented first-year ROI multiples above 3x to 4x on ambient documentation investments (dataintelo.com), and the savings math is what makes the federal buyer, not just the commercial health system, willing to underwrite a national rollout.
The Department of Defense is the logical next federal customer. On-premises deployments still account for roughly a quarter of the ambient clinical documentation market, and that share is concentrated in large academic medical centers, VA facilities, and DoD healthcare networks (dataintelo.com), exactly the security- and latency-sensitive environments where cloud-native vendors have historically struggled to land. Knowtex has positioned its architecture around that constraint, and the VA's selection of it as the first such deployment inside CPRS gives DoD program offices a working reference deployment rather than a slide deck. The broader federal pull is also tightening: HHS announced in February 2026 that nearly 500 million health records had been exchanged through the TEFCA national interoperability network while emphasizing AI to reduce costs and improve data accessibility, and the CDC's FY 2026–2030 AI Strategy, released in April 2026, extends that mandate into surveillance and outbreak detection (marketsandmarkets.com).
Talent pipelines are already bending toward that federal scale-up. First-party board data shows Abridge hiring across data science, machine learning, and AI-focused legal roles in the past week, including a Head of Data Science role banded at $250,000–$325,000 and a Software Engineer, Generative AI position at $255,000–$300,000, while Nuance Labs is adding research staff in Seattle and Ambient is staffing up applied research and AI infrastructure roles in Redwood City. That hiring pattern (applied research, ML infrastructure, and privacy-counsel hires in parallel) is what a federal-grade ambient scribe rollout looks like before the contract awards are even announced. The pressure now sits with the DoD to convert the VA's reference deployment into its own multi-site program before the 150,000-user VA milestone lands.
