About
Pathos AI is a clinical-stage AI company building the world's largest multimodal oncology AI platform, combining pathology imaging, genomics, clinical records, and treatment outcome data to power precision cancer care. Founded by oncologists, pathologists, and AI researchers, Pathos has assembled a dataset at a scale that gives its models a meaningful edge: by ingesting vast quantities of multimodal cancer data, its platform can predict treatment responses, identify biomarkers, and guide therapy selection with a level of accuracy that single-modality systems cannot match.\n\nThe platform serves oncologists and cancer centers by providing AI-augmented pathology reads, treatment outcome predictions, and clinical trial matching. Pathos's AI can analyze whole-slide pathology images in combination with molecular and clinical data to generate insights that inform diagnosis and treatment decisions. The company has also built partnerships with pharmaceutical companies — including Novo Nordisk and Prelude Therapeutics — to use its platform for drug development and clinical trial design, adding a biopharma revenue stream alongside its clinical business.\n\nPathos raised $365M in a Series D round at a $1.6B valuation, bringing total funding to $467M. The Series D was one of the largest oncology AI fundraises in history and included backing from top-tier life sciences investors. The Novo Nordisk and Prelude partnerships validate the platform's scientific depth and its utility across both clinical care and drug development. As of 2025–2026, Pathos is advancing toward direct clinical deployment and regulatory submissions, positioning itself as a core infrastructure layer for the future of AI-guided cancer treatment.

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.
