Doximity — Business Overview

What does Doximity do?

Doximity runs the largest professional network for U.S. physicians and medical professionals, and it monetizes that network by selling tools to healthcare companies that want to reach those professionals. Think of it as LinkedIn, but built exclusively for doctors — and free for them to use. As of March 2025, the platform had over two million registered members, including more than 80% of U.S. physicians, over 60% of nurse practitioners and physician assistants, and over 90% of graduating U.S. medical students.

The platform offers three types of commercial solutions to paying customers, primarily pharmaceutical manufacturers and health systems:

The platform itself — including the professional profile, secure messaging, fax, telehealth, and newsfeed — is free for medical professionals.

How does Doximity make money?

Doximity's revenue model is primarily subscription-based, charging healthcare companies for access to its physician audience. Pharmaceutical manufacturers buy marketing programs brand by brand. Health systems buy marketing programs service line by service line (for example, cardiology or oncology). Hiring customers pay subscription fees for a set number of job postings or direct messages to candidates. Workflow tools like Dialer Enterprise and AMiON are sold as enterprise-level subscriptions with added service layers. Curative Talent, the staffing arm, earns fees on an hourly or placement basis.

The revenue model benefits from natural expansion within existing customers. Pharmaceutical customers typically start with a few brands, then add more brands and more advertising modules once they see results. Health systems do the same across additional service lines. This makes the existing customer base a significant source of organic revenue growth.

What market does Doximity operate in?

Doximity sits at the intersection of digital healthcare marketing, physician recruitment, and clinical workflow software — all growing markets driven by the healthcare industry's shift away from in-person sales reps and paper-based processes. Pharmaceutical companies have been increasing digital marketing budgets as traditional channels (like office visits by drug reps) became harder to execute and less effective. Health systems face persistent staffing shortages, making digital recruitment tools increasingly valuable.

Secular tailwinds support the business. Telehealth adoption accelerated through the COVID-19 pandemic and has remained elevated. AI-powered workflow tools are a fast-growing category as healthcare systems look to reduce physician administrative burden (often called "physician burnout"). Regulatory requirements around HIPAA-compliant communication also create a structural need for purpose-built tools rather than consumer apps like WhatsApp or Zoom.

Who are Doximity's main competitors?

Doximity claims a unique position as the only professional network built exclusively for medical professionals, which makes direct comparisons to competitors imperfect. For member attention, it competes with general social and professional networks like LinkedIn, Facebook, Google, and X, as well as health-focused platforms like WebMD's Medscape. However, Doximity argues that none of these are purpose-built for clinical workflows or have its breadth of physician coverage.

Competition varies meaningfully by product line:

• Marketing: Health-related websites and apps, particularly Medscape, compete for pharmaceutical advertising budgets.
• Hiring: Large healthcare staffing companies, regional job boards, and self-service recruiting tools.
• Workflow/IT: General-purpose communication tools like Zoom and Microsoft Teams, dedicated telehealth providers like Teladoc Health and Amwell, scheduling tools like QGenda, and an emerging set of AI-focused healthcare software startups.

The key competitive advantage Doximity cites is its network scale and data depth. With over 80% of U.S. physicians already on the platform, the member database is extremely difficult for any competitor to replicate from scratch. The company also highlights that its proprietary data set — built from hundreds of millions of member interactions — powers personalization and targeting that competitors cannot easily match. The company has 830 full-time employees as of March 2025, with more than a third working in research, development, engineering, and data — suggesting heavy investment in maintaining that technology edge.

Where does Doximity operate?

Doximity is almost entirely a U.S.-focused business. Its network spans all 50 states and covers physicians across every medical specialty. Its paying customers — pharmaceutical manufacturers and health systems — are also primarily U.S.-based organizations. The company's headquarters are in San Francisco, California.

The company does use international contractors and consultants to supplement its workforce, but its commercial activity, membership base, and regulatory framework are all anchored in the United States. The filing notes that if Doximity were to expand internationally in the future, foreign laws may not protect its intellectual property to the same degree as U.S. law — suggesting international expansion is a possibility being considered but not yet underway. For now, investors should view this as a domestic-only business.
