Doximity

Doximity is a United States digital platform designed primarily for physicians and other healthcare professionals. It combines professional identity and networking features with curated medical news, case discussion, secure communication, telehealth tools, scheduling resources, recruitment services, and commercial communications directed at healthcare audiences. The company was founded by Nate Gross, Jeff Tangney, and Shari Buck around 2010 and launched its service in March 2011. Jeff Tangney has served as chief executive during the company’s development and through its public listing. The platform’s central proposition is that medical professionals can use one verified professional network for activities that are otherwise distributed across general-purpose social networks, email, telephone systems, job boards, and clinical information services. Doximity profiles can function as professional directories, while the network supports news consumption, peer communication, case collaboration, job discovery, and interactions with healthcare organizations and life-sciences companies. Its audience has historically been concentrated in the United States, where the company reported rapid adoption among physicians, nurse practitioners, and physician assistants. Doximity expanded beyond networking through communications products. In 2016 it introduced Dialer, a tool that enables physicians to call patients from a personal mobile phone while displaying the physician’s office number rather than the private mobile number. In 2020, during the rapid expansion of remote care, it introduced Dialer Video, allowing physicians to conduct video visits from smartphones. The company stated that more than 100,000 U.S. doctors were using Dialer Video by July 2020. These services positioned Doximity as part of the healthcare communications infrastructure as well as a professional media and networking company. Recruitment became another important area of activity. In June 2020 Doximity acquired THMED, a healthcare staffing and recruiting business, and subsequently operated the business under the Curative name. The staffing operation provided permanent and temporary or locum placement services. In February 2022 Doximity acquired Amion, a physician on-call and scheduling company, extending its presence into clinical workforce coordination. Reference material also reports an August 2025 acquisition of Pathway Medical, a Canadian company focused on medical artificial intelligence and evidence-based clinical reference tools. Doximity raised venture financing before becoming public, including investments from Emergence Capital Partners, InterWest Partners, Morgenthaler Ventures, Draper Fisher Jurvetson, T. Rowe Price, and Morgan Stanley Investment Management. It filed for an initial public offering in May 2021 and completed a June 2021 listing on the New York Stock Exchange under the symbol DOCS. The offering reportedly raised nearly $606 million, and the company’s market capitalization shortly after debut was reported at approximately $9.4 billion; these figures relate to the 2021 offering period rather than current valuation. The company’s growth has also brought scrutiny. In 2021, reporting described vaccine misinformation appearing in Doximity’s news feed even though the platform’s rules prohibited medical misinformation. The episode highlighted the moderation challenges created by a large professional network, particularly when advertising revenue and audience engagement are connected to pharmaceutical and hospital advertisers. In November 2023, Doximity released DocDefender, a free privacy service intended to help physicians remove personal telephone numbers and addresses from publicly accessible websites. Doximity remains an active, publicly traded healthcare technology brand focused principally on the U.S. medical professional market.

Doximity emerged from the founders’ effort to create a professional online network tailored to the way clinicians work. Nate Gross, Jeff Tangney, and Shari Buck established the company around 2010, and the service launched in March 2011. Rather than presenting itself as a general social network, Doximity focused on professional identity, verified medical membership, peer communication, medical news, case discussion, and career activity. Jeff Tangney remained chief executive as the business developed in California. The service gained adoption quickly among U.S. healthcare professionals. By 2013, approximately one in ten U.S. doctors was reported to be a member. By early 2014, the reported share had risen to roughly 40 percent of U.S. physicians. Doximity’s reach continued to expand, and in 2018 the company announced that it had passed one million members, representing more than 70 percent of U.S. physicians. By 2021, it reported more than two million registered members, including over 80 percent of U.S. physicians and more than half of U.S. nurse practitioners and physician assistants. Doximity broadened its platform with communications and telehealth products. In 2016 it introduced Dialer, which allowed a physician to place a patient call from a personal mobile phone while showing an office number to the recipient. This addressed a practical privacy and accessibility problem for clinicians. In May 2020, as remote care accelerated, Doximity added Dialer Video. The product enabled physicians to conduct video calls with patients through smartphones, and the company said that more than 100,000 U.S. doctors were using it by July of that year. The company also expanded into recruitment and staffing. Its June 2020 acquisition of THMED brought a healthcare staffing business into the organization. The acquired operation was renamed or branded Curative and focused on customized healthcare personnel searches, including permanent and locum or temporary placements. In February 2022, Doximity acquired Amion, an on-call physician scheduling service, adding a workforce-coordination capability. Reference material further identifies an August 2025 acquisition of Pathway Medical, a Canadian startup focused on medical AI and evidence-based clinical reference products. Doximity’s financing history included a $10.8 million investment from Emergence Capital Partners and InterWest Partners in March 2011, followed by a $17 million Series B round led by Morgenthaler Ventures in September 2012. In April 2014, the company announced a $54 million financing led by Draper Fisher Jurvetson and T. Rowe Price, with participation from Morgan Stanley Investment Management. The 2014 round brought reported total funding to $81 million. Doximity later filed for an initial public offering in May 2021 and listed on the New York Stock Exchange in June under DOCS. Reference material reports that the IPO raised nearly $606 million and that the company’s market capitalization shortly after debut reached approximately $9.4 billion. The company’s scale created both commercial opportunity and governance challenges. Its platform connected a large physician audience with pharmaceutical companies, hospitals, recruiters, and other healthcare organizations. In 2021, CNBC reporting described vaccine misinformation circulating in the news feed even though Doximity’s guidelines prohibited medical misinformation. The incident placed attention on content moderation, professional trust, and the tension between a physician-focused media environment and advertising-supported distribution. In November 2023, Doximity introduced DocDefender, a privacy-oriented tool designed to help doctors remove personal contact information from public websites. The brand remains active and primarily serves the United States medical professional market.
