About
adyn is a precision medicine company developing personalized birth control solutions through at-home testing kits that analyze hormone levels and genetic risk factors — enabling individuals to choose hormonal contraceptives based on their own biology rather than trial-and-error, addressing a gap where most people cycle through multiple birth control options over years to find what works without causing intolerable side effects. Founded in 2019 and a Y Combinator graduate, adyn raised $2.65 million in seed funding co-led by Lux Capital and M13, with the Birth Control Optimization Test positioned as the first biology-based test for contraceptive personalization.

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.
