Fathom

Based in Cleveland, Ohio, Fathom is a digital marketing agency that works specifically with hospital systems and health systems rather than a broad cross-industry client base. It operates as part of IQVIA, a global provider of clinical research services, commercial insights and healthcare intelligence, which gives Fathom's team access to healthcare-specific data resources when building client strategies. The agency's stated client tenure averages seven years, which it presents as evidence of long-term relationships with healthcare marketing departments, including named clients such as Penn Medicine and Henry Ford Health System. Fathom's declared service lines cover Search Engine Optimization, Digital Strategy, Email Marketing, Pay Per Click, Social Media Marketing, and Content Marketing, all framed around the particular regulatory and audience challenges of healthcare marketing. Its case study work includes patient-centric targeting campaigns designed to drive service line growth, such as a breast cancer surgical treatment campaign for Penn Medicine. The agency also publishes industry insights aimed at hospital marketing teams, including commentary on the use of AI in healthcare advertising, indicating an emphasis on tracking emerging channels within a regulated sector. Fathom describes its approach as combining data access through its IQVIA affiliation with dedicated account teams that focus on understanding a health system's specific business strategy and marketing communications goals. The team size is listed between 11 and 50 people.
