Rad AI focuses on empowering physicians with AI – saving physicians time, reducing burnout and improving the quality of patient care, and has become a mission-critical part of physician and health system workflows across North America. Rad AI's models are trained on some of the largest healthcare datasets in the world through exclusive partnerships with leading health systems and radiology practices, and the company has seen rapid adoption by health systems across the country, with revenue tripling year-over-year.
Cyborg Score Rationale
Rad AI closed a $60M Series C in January 2025 at a $525M valuation and secured an additional $8 million in May 2025 as part of a Series C extension, bringing total Series C funding to $68 million with contributions from four major health systems. Market validation is evident through broad adoption and revenue growth, though competitive threats from incumbent RIS vendors embedding AI capabilities present execution risks.
Top Insights
Radiology accounts for nearly 10% of all US healthcare spend with over 700 million imaging exams annually, yet 88.4% of radiologists are at capacity or overworked.
Rad AI has increased follow-up rates at health systems from 30% to 75% or more, leading to earlier diagnoses of new cancers.
Rad AI's solutions are used by more than one-third of all US health systems and 9 of the 10 largest US radiology practices.
Incumbents like Nuance are embedding generative AI directly into widely used systems (e.g., PowerScribe), presenting competitive risk if hospitals favor integrated platforms over modular tools.
