The fast-growing health care IT firm is benefiting from the mass migration to electronic health records and push to connect disparate platforms to merge patient information for easy retrieval by doctors. Indeed, InterSystems' growth is closely tied to that of Epic Systems, a leading electronic health records vendor and the company's single biggest customer.

The Saudi Ministry of Health is encouraging the migration of health information online.
