Doximity
Platform · this deep dive is built from the official pages of the platform itself and of the tools that support it.
Overview
Doximity is a closed professional network for US healthcare workers. You can only get inside after your identity and professional credentials have been verified, and that shapes everything else: what is visible there, and who is allowed to say anything at all.
The company is public, so its arrangement is described not by marketing copy but by an annual report. The report for fiscal year 2026 states that member identity and credentials are verified through an integration with third-party databases, and for most clinicians the platform pre-populates a profile from publicly and commercially available third-party data, which the member then fills in. The same document says that the platform is free for US healthcare workers, and that the money comes from others — drug manufacturers and hospital systems.
On its about page the company calls itself the "largest verified network of US medical professionals". For a communications specialist this is a platform of an entirely special kind: there is no organic marketing here, and all commercial access is paid, contract-based and regulated. Below we go through the arrangement and the rules. This article contains no advice on promoting pharmaceutical products, and it cannot contain any.
Who's here
The annual report for fiscal year 2026 gives precise wording: more than 3 million registered members as of 31 March 2026; they represent more than 85 % of US physicians across every specialty and all 50 states, two thirds of nurse practitioners and physician assistants (NPs and PAs), and roughly 90 % of US medical school graduates.
Note the denominator — the company discloses it itself: "US physicians" means holders of an MD or DO degree under the age of 76, not retired, with an active licence and physician status in the NPI registry; as of 31 March 2026 there were about 1 million of them. The same report separately warns that operating metrics are calculated by the company's internal systems and are not verified by an independent party. This is the company's statement about itself, not an independent measurement.
The geography is strict: the terms of service say that Doximity is a US company, data is stored in the US, the service is intended for US users, and the company does not target users in other jurisdictions. There is no Russian-language or any other localization: the only interface language is English.
Activity is measured separately from registrations: the fourth-quarter results announcement names more than 800,000 unique active physicians who used the workflow tools during the quarter.
Getting started
The entry threshold is spelled out in the terms: by registering, you confirm that you are at least 18 years old, that you are a physician, medical student or other US healthcare worker, and that the information about your professional credentials is accurate and complete. Then comes verification: the report describes it as a "simple identity and credential verification", after which you get access to the network, the feed and — depending on your credentials — to a set of clinical tools.
A practical detail about starting out: more often than not the profile has already been created for you. The report says outright that the platform pre-populates the profile from third-party data, and the member then fills it in and refines it — that is, entry usually begins not with registration but with claiming an already existing card.
For an advertiser company the path is different and involves no self-service registration: access is bought via subscription, which is covered below. Separately there are paid subscriptions for individuals: the terms state that membership is not required to buy a subscription, but certain services, for example Dialer Pro, are available only to verified healthcare workers, subscriptions renew automatically, and the company gives notice of renewal by email at least 15 days in advance.
What you can publish
A member can write in their profile, in the feed, in direct messages and in the AI-based tools. The terms set content standards: what is prohibited is abusive, profane, defamatory, obscene or threatening material; calls to unlawful action and discrimination; infringement of other people's rights; misrepresenting your current or past affiliation with an organization.
The point that matters most for marketing is in the same place: user content must not contain advertising or promotion that Doximity has not authorized in writing. And separately on correspondence: the member-to-member communication tools are permitted for clinical, non-commercial purposes unless Doximity has expressly agreed otherwise. Put simply, "come in and message the doctors" is not possible here — it is a breach of the terms, not a grey area.
There is also a prohibition on using the platform as a source of quotations: the terms require you not to use or republish someone else's content without written permission from Doximity or from the author.
How to grow
There is no organic growth here in the usual sense. The company describes neither a feed ranking algorithm, nor profile promotion tools, nor built-in statistics for the member. The only described way to reach physicians is to buy a subscription to the commercial products.
The annual report describes the product like this: Marketing Solutions — placement of client-paid content on the Doximity platform and access to the professional database of healthcare workers for outreach or marketing during the subscription term. Pricing is described openly: the price depends on the number and composition of the members a campaign targets and on the set of modules purchased, and integrated subscriptions cap the number of modules launched per period, the number of modules active at once, and the number of members in the audience.
On its storefront for clients the company cites its own figures: 3 million members, "4 out of 5 US physicians", a median return above 9.6:1 and work with the top 20 drug manufacturers. These are the platform's own claims in a marketing document; the median return is Doximity's own metric, not an independent assessment, given without a calculation method, sample or period. The storefront also puts the NP and PA share differently from the annual report: 50 % against two thirds — the sources disagree. There are no rate cards on the public pages: sales are contract-based.
Path to monetization
Doximity does not pay physicians. There is no share of advertising revenue, no creator fund and no subscribe-to-an-author feature here; the report calls the platform free for US healthcare workers, and in this model the money moves the other way — from clients to the platform.
The scale of that flow is disclosed: revenue came to $644.9 million in fiscal year 2026 against $570.4 million in 2025 and $475.4 million in 2024, that is growth of 13 % and 20 % respectively; net income for 2026 was $196.1 million. Revenue is heavily concentrated: there were 125 clients with more than $500,000 in trailing 12-month subscription revenue, against 118 and 100 one and two years earlier, and they accounted for about 83 % of 2026 revenue. The net revenue retention rate was 109 % for 2026 against 119 % and 114 % for the two preceding years.
The only form of "earning" for individual members named in the terms is work under a separate arrangement: Doximity works with selected members who prepare content and services for the service, including reviewing AI-generated responses.
Tools and automation
Programmatic access exists, but it is narrow. The developer section offers verification of a user's identity against the Doximity database, simplified registration via a Doximity profile and a "share" button, as well as Dialer libraries for iOS and Android.
The documentation sets the rules of the game: access is granted via OAuth 2.0 with OpenID Connect once Doximity approves the application; the limit is 5000 requests per hour; you may not cache user data beyond the current session, and you are only allowed to store identifiers and tokens. Through userinfo you are given the identifier, first, last and middle name, titles, specialty and a link to the profile photo — and nothing more.
The prohibitions in the documentation are direct: you may not combine API data with scraped Doximity content, charge users for access to Doximity data, use the data for advertising and targeting, pass access on to other companies, or build competing applications. The advertising clause matters more than the rest here: the API is not a channel for advertising work.
The terms repeat this at the service level: it is prohibited to use programs, scripts, robots and crawlers to view, extract and "scrape" the service, and also to extract, copy, store and distribute any part of it for commercial purposes without written permission. Under these conditions the existence of third-party scheduling or analytics services within the legal boundaries is unlikely.
Limits and rules
- Who is inside. Only US healthcare workers aged 18 and over with accurate professional credentials; verification runs through third-party databases.
- Geography. The service is intended for the US, data is stored in the US, and the company makes no claim on other jurisdictions.
- Advertising outside a contract. Sending advertising and promotional material without prior written consent is prohibited, including mass mailings and "spam".
- Industry law. The terms require you not to violate laws and professional standards, including HIPAA on patient confidentiality, the Stark law on patient self-referral and the TCPA on calls and messages; the annual report adds that the company is indirectly subject to federal and state anti-kickback and fee-splitting laws.
- No drug recommendations from the platform. The terms establish that Doximity does not practise medicine and does not recommend, endorse or advise on specific drugs, tests, physicians, treatments or off-label use of medicines.
- Adverse events. Doximity's AI tools are not a channel for reporting adverse events involving drugs and devices; those should be reported to the manufacturer or through FDA channels.
- Disputes. Mandatory individual arbitration and a class action waiver.
Who it's for
It suits pharmaceutical companies, hospital systems and US medical recruiters that have the budget for a contract subscription and in-house compliance control: the audience here is extremely precise, but the only way in is through sales. The order of magnitude is clear from the revenue concentration — clients above $500,000 a year deliver about 83 % of the platform's revenue.
It suits developers of medical services who need to verify a physician's identity or offer fast registration: the API supports these two scenarios directly.
It does not suit anyone outside the US — the service does not reach out there. It does not suit organic brand promotion, influencer marketing or mailings: the non-commercial nature of member-to-member communication and the ban on unauthorized advertising are written into the terms. It does not suit agencies used to self-service: there is no dashboard with rate cards.
