Doximity

Doximity has evolved into the central digital operating system for over 80% of U.S. physicians as of 2026. Its technical architecture combines a secure professional social graph with robust clinical workflow tools. The 2026 market position is defined by its 'Doximity GPT' integration—a HIPAA-compliant implementation of large language models specifically tuned for medical administrative tasks. This platform utilizes proprietary data layers and medical prompt engineering to assist clinicians in drafting prior authorizations, patient education materials, and referral letters. Furthermore, its 'Dialer' technology enables seamless telehealth transitions via WebRTC protocols, allowing providers to call patients from personal devices while masking their caller ID with office numbers. Strategically, Doximity bridges the gap between siloed Electronic Medical Records (EMRs) and mobile-first clinical communication, serving as both a recruitment engine for health systems and a productivity suite for independent practitioners. Its infrastructure is built for high security, meeting SOC2 and HIPAA standards to handle sensitive Protected Health Information (PHI) across its messaging, faxing, and video call modules.
