company snapshot

Doximity (NYSE: DOCS) is the leading professional network for U.S. physicians, with more than one million members, including more than 80% of doctors and 50% of nurse practitioners and medical assistants. With Doximity, providers can use their mobile device or computer to securely connect and collaborate with other providers about patient treatment, identify appropriate experts for patient referrals, receive customized newsfeeds, and manage their careers with the help of medical credentialing, scheduling, and recruitment resources. In 2020, the company added functionality to allow provider members to perform telemedicine visits with their patients, and with the tailwinds from COVID dynamics, Doximity rapidly became one of the leading telemedicine platforms. Doximity’s unique nationwide physician network and strong track record of rapid revenue growth, combined with impressive profitability, enabled the company to execute on a highly successful NYSE IPO in June 2021 at a valuation exceeding $4B.

The company was founded in 2010 by Jeff Tangney while he was an Entrepreneur-in-Residence at InterWest, and InterWest was Doximity’s first institutional investor. Managing Partner Gil Kliman played a lead investor and board role since inception and served on Doximity’s board of directors from 2011 to 2022. Gil previously backed Jeff Tangney in his first company, Epocrates, which pioneered the first mobile app for physicians. InterWest was a founding investor in Epocrates, which was acquired post 2011 IPO by athenahealth.
