Avise provides specialized diagnostic tests for autoimmune diseases including lupus and rheumatoid arthritis that help rheumatologists make faster and more accurate diagnoses.
About
Avise Medical is a specialty diagnostics company founded in 2012 that develops laboratory tests specifically designed to help rheumatologists diagnose and monitor autoimmune diseases including lupus, rheumatoid arthritis, and related conditions. The company's flagship products include AVISE Lupus, a panel of blood biomarkers that increases diagnostic accuracy for systemic lupus erythematosus compared to traditional single-marker tests, and AVISE CTD for connective tissue disease diagnosis. Autoimmune diseases are notoriously difficult to diagnose because symptoms overlap with many other conditions and individual biomarkers have limited sensitivity and specificity. Avise addresses this through multi-biomarker panels that use machine learning to combine signals into diagnostic scores with better performance characteristics. The company works directly with rheumatology practices and provides specialized clinical interpretation support for complex cases. Avise raised over $100M and expanded its diagnostic portfolio to cover monitoring of disease activity and treatment response in addition to initial diagnosis. The company represents the application of advanced biomarker discovery and machine learning to specialty diagnostics in rheumatology.

About
athenahealth is a cloud-based electronic health records (EHR), medical billing, and practice management company founded in 1997 and headquartered in Watertown, Massachusetts.

The company serves ambulatory practices ranging from solo physicians to large health systems and medical groups. Its continuously updated rules engine processes millions of payer transactions daily, enabling higher clean claim rates and faster reimbursement compared to on-premise EHR alternatives. athenahealth holds an 18.15% share of the US ambulatory EHR market.\n\nathenahealth is currently owned by a private equity consortium of Bain Capital and Hellman & Friedman, which acquired the company in 2019 for $5.7 billion. Annual revenue stands at approximately $1.7 billion. The company competes with Epic, eClinicalWorks, and Oracle Health in the ambulatory EHR market. Its managed-service model, shared payer network data, and cloud-native infrastructure continue to make it a compelling choice for ambulatory providers who prioritize revenue cycle performance and reduced administrative burden.
