About
Willow is a digital health company that develops AI-powered software to streamline administrative operations and enhance patient engagement for healthcare providers. The platform addresses the pervasive administrative burden in medical practices — which accounts for roughly 30% of total US healthcare spending — by automating workflows including patient scheduling, appointment reminders, intake form collection, insurance verification, post-visit follow-up, and care gap outreach. Willow integrates with major electronic health record (EHR) systems to insert automation into existing clinical workflows without requiring staff to adopt new primary systems, making it particularly accessible to independent practices, specialty groups, and community health centers that lack large IT teams.

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 was built on the principle that healthcare administration should be managed as a service — with athenahealth absorbing the complexity of payer rule updates, regulatory compliance, and billing workflows so that physicians and clinical staff can focus entirely on patient care. Its cloud-native architecture, deployed before most EHR competitors moved to the cloud, remains a core technical differentiator.\n\nathenahealth's platform — athenaOne — integrates EHR, revenue cycle management, patient engagement, and care coordination in a single system used by over 160,000 providers across 117 million patient records. 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.
