Doximity, Inc.

The professional network that most US physicians actually use. Free to clinicians, it makes its money by selling pharmaceutical companies and hospitals access to those clinicians, for brand marketing and for recruiting. It became one of the most profitable companies in digital health by giving doctors free tools (fax, a calling app, video visits, scheduling and, since 2023, generative AI) that keep them logging in, then charging the buyers who want their attention.
