Abridge

Abridge was founded in 2018 by Dr. Shiv Rao, a practicing cardiologist at UPMC, and Zachary Lipton, a machine-learning researcher formerly at Carnegie Mellon University. The company is headquartered in Pittsburgh, Pennsylvania, and has grown into one of the most prominent players in healthcare AI. Its ambient scribe is deployed at more than 250 health systems, including Kaiser Permanente's rollout across roughly 40 hospitals and 600+ medical offices, plus Mayo Clinic, Duke Health, Johns Hopkins, Sutter Health, UCSF, Yale New Haven and Emory.

Abridge has earned Best in KLAS for Ambient AI in 2025 and 2026 and became Epic's first generative-AI 'Pal' partner. Independent analysts estimated the company reached roughly $100M in ARR in 2025, reflecting rapid enterprise adoption.

The core product is an ambient AI scribe that captures the natural conversation of a clinical visit and generates a structured, specialty-aware note that drops into the EHR. Abridge supports 55+ medical specialties and 28+ languages, including production-grade Spanish note generation. Its Linked Evidence feature ties every note section to the exact transcript and audio segment that produced it, giving clinicians a way to verify AI output rather than trusting it blindly.

The flagship differentiator is depth of Epic integration: through 'Abridge Inside,' clinicians record in Haiku or Canto and see AI notes populate the chart in Hyperdrive without leaving Epic, with specialized workflows such as Abridge Inside for Emergency Medicine. Abridge also produces patient-friendly visit summaries, and reports that users save around two hours per day on documentation with substantially less after-hours charting.

Abridge sells exclusively to enterprise healthcare organizations: hospitals, integrated delivery networks, academic medical centers and large multi-specialty medical groups, with a strong bias toward Epic-based institutions. Solo practitioners and small independent clinics cannot purchase Abridge directly, as the product requires an organizational contract. Buying decisions typically involve CMIOs, CIOs, clinical informatics leaders and physician leadership focused on reducing documentation burden and clinician burnout at scale.

Abridge has raised approximately $800M+ in total venture funding. In February 2025 it announced a $250M Series D, and in June 2025 a $300M Series E led by Andreessen Horowitz (a16z) and Khosla Ventures that valued the company at $5.3B, roughly doubling its valuation within about four months. Backers include a16z, Khosla Ventures, Lightspeed, IVP, Redpoint, Bessemer and others. Exact cumulative totals vary by source, but the $5.3B valuation and $300M Series E are the most recent publicly reported figures.
