Side-by-side comparison of AI visibility scores, market position, and capabilities
a2z Radiology AI raised $20M in 2025 for its whole-body AI that simultaneously screens for 24+ conditions across CT scans — from incidental cancers to cardiovascular risk — in a single automated read.
a2z Radiology AI has developed a whole-body CT analysis platform that simultaneously screens for over 24 medical conditions across a single CT scan, including incidental cancers, coronary artery disease, aortic aneurysm, bone density loss, and organ abnormalities. The AI acts as a second reader that radiologists can use to catch incidental findings that fall outside the primary reason for a scan — a major source of missed diagnoses.
Major ambulatory EHR serving 150K providers bootstrapped to scale; Sunoh.ai ambient clinical documentation and revenue cycle management competing with Epic and athenahealth for practices.
eClinicalWorks is one of the largest electronic health record (EHR) and practice management software providers in the United States, serving approximately 150,000 providers across 850,000 care sites with ambulatory EHR, revenue cycle management, patient engagement, and population health tools. Founded in 1999 by Girish Navani and headquartered in Westborough, Massachusetts, eClinicalWorks is privately held and is notable for being a bootstrapped company that has grown to significant scale without venture capital funding, generating substantial annual revenue from its large installed physician base.\n\neClinicalWorks' platform covers the ambulatory (outpatient) clinical workflow: clinical documentation with specialty-specific templates, order entry for labs and imaging, e-prescribing, chronic disease management registries, telehealth (healow TeleVisits), and patient portal. The revenue cycle management capabilities handle insurance claims submission, denial management, and patient billing. Population health tools enable practices and health systems to identify at-risk patient populations and coordinate care across attributed patients.\n\nIn 2025, eClinicalWorks competes with Epic (the dominant health system EHR), athenahealth (cloud-native ambulatory EHR), Oracle Health (Cerner), and Modernizing Medicine for physician practice EHR market share. The company has faced regulatory challenges — in 2017, eClinicalWorks paid $155 million to settle Department of Justice charges related to EHR certification fraud. Despite this, the company retained most of its customer base due to high switching costs inherent in EHR changes. The 2025 strategy focuses on its AI assistant Sunoh.ai (ambient clinical documentation that automatically generates SOAP notes from recorded patient visits), expanding telehealth capabilities, and growing the healow patient engagement platform.
