Epic Systems is perhaps the most successful health technology company in the world. Its electronic health record (EHR) platform is now used by the majority of large health systems in the U.S. Its customers are vocal in their support and are often passionate defenders of the platform’s reliability, configurability, and comprehensiveness. And its commercial success continues: according to newly released KLAS Research data, Epic gained even more market share in 2024, widening the gap between itself and competitors.
