👥 What types of companies is most likely to use eClinicalWorks?

Source: Analysis of Linkedin bios of 1,628 companies that use eClinicalWorks

I analyzed these companies and found that eClinicalWorks primarily serves healthcare providers delivering direct patient care. These are medical practices, community health centers, hospitals, and specialty clinics where doctors, nurses, and medical staff see patients daily. They're not building products or selling goods. They're providing medical services ranging from primary care and pediatrics to specialized fields like cardiology, orthopedics, gastroenterology, and mental health. Many are Federally Qualified Health Centers serving underserved populations.

These are established, mature organizations rather than startups. The signals are clear: most have been operating for decades (one since 1872, another since 1947), they employ anywhere from 2 to over 10,000 staff, they operate multiple locations, and many hold accreditations from organizations like The Joint Commission or designations as Patient Centered Medical Homes. Very few show any funding history, and those that do are nonprofits receiving grants rather than venture-backed companies.
