Epic Systems
America's largest electronic health records (EHR) software company, serving hundreds of millions of patients worldwide.
Epic Systems – WikipediaEpic Systems Corporation is a privately held American healthcare software company founded in 1979 by Judith Faulkner and headquartered in Verona, Wisconsin. It develops large-scale electronic health record (EHR) systems and is the largest EHR vendor by market share in the United States, with roughly $5 billion in annual revenue and approximately 13,000 employees on its 1,670-acre campus.
Epic's core product is its proprietary Epic EMR application, built on the Chronicles database management system. Its patient-facing platform, MyChart, is used by 150 million patients across the U.S. for scheduling appointments, accessing records, refilling medications, messaging care teams, and billing. The company reports that more than 325 million patients have an electronic record in Epic.
Epic serves a broad range of healthcare organizations including community hospitals, academic medical centers, children's hospitals, safety net providers, and multi-hospital systems. From the late 2010s, Epic expanded into Europe, selling to countries with universal healthcare systems such as the UK, Denmark, Finland, and Norway. In January 2025, North Somerset Council approved plans for a 90-acre European headquarters campus near Bristol, UK.
Epic competes with Oracle Health, MEDITECH, Allscripts, Athenahealth, and healthcare IT units of IBM, McKesson, and Siemens. Given its dominant position in managing clinical and patient data at scale, Epic is highly relevant to innovations in healthcare data interoperability, AI-assisted clinical decision-making, and patient engagement technology.
Ideas that could help Epic Systems
- Proximate-Cause Disease Ontology Engine
A clinical decision-support layer that organizes diseases into a strict hierarchical taxonomy (class → order → genus → species) keyed to their proximate biological causes, automatically surfacing mechanism-matched treatments rather than symptom-matched ones.
Why it helps: Epic's clinical decision-support modules sit inside EHR workflows; an etiology-first disease taxonomy could be licensed as an ontology layer that improves treatment recommendation accuracy inside their existing physician-facing tools.
- Chronic-Disease Patient Digital Twin for Personalized Treatment Planning
A clinical AI service that builds a continuously updated virtual model of an individual patient with a chronic condition — diabetes, heart failure, or respiratory disease — enabling clinicians to simulate treatment adjustments before prescribing them.
Why it helps: The dominant US EHR vendor; integrating patient DT capabilities as a licensed module would offer hospitals a high-value add-on and positions Epic ahead of competing platforms in the AI-augmented care race.
- Culturally-Calibrated Body Image Screening Tool
A digital clinical screener for primary care and school counselors that adjusts body-image and self-esteem risk thresholds by the patient's cultural background and gender, surfacing at-risk individuals who would be missed by universal BMI or appearance-satisfaction norms.
Why it helps: As the dominant EHR vendor, Epic embedding this screener as a configurable intake module would give it immediate reach into thousands of health systems and streamline clinical adoption.
