What Rad AI does
Rad AI is a privately held healthcare AI company founded in 2018 and headquartered in San Francisco that builds generative AI software for radiology workflows. Its platform is composed of three core products: Rad AI Reporting (a generative AI reporting platform that adapts to each radiologist's voice and style), Rad AI Impressions (automated impression generation from dictated findings), and Rad AI Continuity (automated patient follow-up management tracking 50+ categories of incidental findings). Underlying technology comprises domain-specific AI models trained on over 500 million radiology reports, deployed on AWS infrastructure (Amazon EC2 P4d instances with NVIDIA GPUs), and a patent-pending multi-model speech recognition architecture with a proprietary voting algorithm. Peer-reviewed validation in npj Digital Medicine reports radiologist preference margins of 28-50% over generic AI, with custom models averaging 34.2 words per impression versus 75.1 words for general-purpose AI.
The company sells primarily through multi-year enterprise subscriptions to U.S. health systems and large radiology practices, priced on a per-radiologist or per-system basis (not publicly disclosed), with go-to-market executed via a dedicated direct enterprise sales team supplemented by channel partnerships with Siemens Healthineers (global reseller), AGFA HealthCare, Blackford Analysis, and MIC Medical Imaging (Canada). Rad AI claims its solutions are used by over one-third of U.S. health systems, touch nearly 50% of U.S. medical imaging volumes, and serve nearly 50 million patients annually. Strategic equity investors include Advocate Health, Memorial Hermann, Corewell Health, and Atlantic Health System (collectively 100+ hospitals), and the company has raised approximately $143 million across three major funding rounds, most recently a $68 million total Series C at a $525 million valuation led by Transformation Capital in January 2025.

Rad AI product offering
Product offeringCore offering
Rad AI develops generative AI software that automates radiology reporting and follow-up management workflows. Its three core products — Rad AI Reporting, Rad AI Impressions, and Rad AI Continuity — generate radiology impressions customized to each radiologist's language, integrate with existing PACS and RIS systems, and automate patient follow-up communications for incidental findings. The platform is used by health systems and radiology practices to reduce dictation burden, cut report errors, and improve follow-up adherence rates.
Product overview
Rad AI offers a unified radiology AI platform consisting of three core products: Rad AI Reporting (a generative AI-powered radiology reporting platform), Rad AI Impressions (automated impression generation from dictated findings), and Rad AI Continuity (automated patient follow-up management for incidental findings). The platform is designed for radiologists by radiologists and integrates seamlessly with existing PACS and RIS workflows. It adapts to each radiologist's individual voice and language patterns, reduces dictation by up to 35%, saves 60+ minutes per shift, reduces burnout by 84%, and improves follow-up adherence from approximately 30% to over 75%. The company also launched next-generation speech recognition technology (patent pending) in December 2025 integrated into the Rad AI Reporting platform.

Rad AI competitors and assessment
Company assessmentEmerging players
- DeepScribe: DeepScribe offers ambient AI medical documentation and scribing for clinicians. Targets the same healthcare AI-documentation category with overlapping enterprise health-system buyers, though its focus is broader than radiology specifically.
- Abridge: Abridge builds generative-AI clinical conversation and note-generation tools for physicians; while broader than radiology, it competes for the same ambient clinical-AI budget and was recently valued above Rad AI. Comparable AI-scribe go-to-market into health systems.
- Notable: Notable builds an AI platform automating clinical and administrative workflows for health systems, including patient scheduling, registration, and documentation. Adjacent product overlap with Rad AI Continuity and the broader workflow-automation positioning.
- Augmedix: Augmedix provides AI-augmented medical documentation, combining ambient AI with remote human scribes. Competes for ambient documentation budgets at health systems that Rad AI is also selling into, with overlap on automation of clinical notes.
- Suki AI: Suki is an AI voice assistant for clinicians that generates notes and integrates with EHR systems. Competes for the same health-system ambient-AI procurement cycles and shares the radiologist/clinician workflow-augmentation thesis.
- Aidoc: Aidoc provides AI-based imaging analysis and workflow triage for radiology (e.g., stroke, PE detection). Overlaps with Rad AI in imaging-AI platform positioning to enterprise radiology departments, though Aidoc's focus is on detection/notification rather than reporting.
Direct peers
- 3M Health Information Systems (M*Modal): M*Modal provides radiology speech recognition and reporting workflows used by large U.S. health systems—the same buyer segment Rad AI targets. Direct overlap in clinical documentation and radiology dictation, competing for the same IT budget line.
- Nuance Communications (Microsoft): Nuance's PowerScribe radiology reporting platform is the dominant incumbent that Rad AI is displacing; the data notes Microsoft is sunsetting PowerScribe 360, directly positioning Rad AI as the replacement. Same end users (radiologists), same PACS-integrated workflow slot.
Broad incumbents
- Siemens Healthineers: Siemens Healthineers is both Rad AI's strategic global reseller and a broader imaging-IT incumbent with its own AI radiology offerings (AI-Rad Companion). Peer-relevant as a competing platform that could in-source similar functionality.
- Philips (Radiology Informatics): Philips is a global imaging and PACS/RIS incumbent whose radiology informatics portfolio (including speech reporting modules) competes with Rad AI for the same health-system procurement cycles, though as part of a much broader device-and-IT platform.
