About
Certainly Health is a San Francisco-based healthcare price transparency marketplace — backed by Y Combinator (S23) with $2.3 million in seed funding in December 2023 from Pacific 8 Ventures, Y Combinator, institutional investors, and angels — providing patients with a doctor booking platform that shows upfront out-of-pocket costs using machine learning to predict and guarantee healthcare spending before appointments, addressing the surprise medical bill crisis where 57% of Americans have received unexpected bills and 38% delay care due to cost uncertainty. Founded in 2023 by Daryl Sew and Kevin Chiu (Stanford graduate, former Uber engineer, and Uber Health founding member who grew that program to $100 million in 2 years), Certainly Health enables patients with insurance to book doctors while seeing the actual cost they will owe — not the sticker price.

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.
