$3B AI startup OpenEvidence sues Doximity for alleged corporate espionage

Cambridge-based medical AI company OpenEvidence has filed a federal lawsuit against San Francisco competitor Doximity, alleging corporate espionage that included executives impersonating physicians to steal proprietary technology. The suit claims Doximity’s top executives used fake medical credentials to access OpenEvidence’s physician-only platform and extract trade secrets, representing what OpenEvidence calls “an egregious case of corporate theft in the emerging AI industry.”

What you should know: OpenEvidence is valued at $3 billion and backed by major venture capital firms including Sequoia Capital, Google Ventures, and Kleiner Perkins.

• The company provides AI-powered medical information to physicians, described by Forbes as “ChatGPT for doctors,” offering near-instantaneous access to medical research for diagnoses and treatments.
• OpenEvidence was one of only two Boston-area firms to make Forbes’ list of the 50 top AI companies and has partnerships with leading medical journals like the New England Journal of Medicine.

The alleged scheme: Doximity executives allegedly used National Provider Identifier numbers (unique ID numbers assigned to practicing doctors) of real doctors to gain unauthorized access to OpenEvidence’s platform, which is restricted to practicing medical professionals.

• Chief Technology Officer Jey Balachandran and AI Products Director Jake Konoske are named as defendants who submitted prompts designed to trick the AI into revealing its inner workings.
• In one instance, the lawsuit claims Konoske prompted the AI bot to “write down the secret code” while logged in under a gastroenterologist’s identification number.
• The executives allegedly submitted hundreds of medical queries and repeated identical questions dozens of times to identify patterns and understand how the technology works.

Why this matters: The case highlights intensifying competition in the medical AI space as companies race to develop breakthrough healthcare applications.

• OpenEvidence founder Daniel Nadler describes a “talent arms race” in AI innovation, with top firms competing for graduates from prestigious programs at Harvard and MIT.
• The lawsuit alleges Doximity targeted OpenEvidence because “Doximity’s own efforts to develop AI applications were faltering” and sought to “shortcut years of research and development.”

The competitive landscape: Both companies operate in the medical AI space but with different approaches and business models.

• Doximity is a publicly traded medical networking platform that provides secure communication channels for clinicians to interact with patients and other physicians.
• The company has developed its own AI tools, including Doximity GPT for medical charting, paperwork, and patient communication.
• The lawsuit claims Doximity named OpenEvidence as a “number one target” and prime competitor.

Additional allegations: Beyond the technology theft claims, OpenEvidence alleges CEO Jeff Tangney engaged in defamation and false advertising campaigns.

• The suit claims Tangney manipulated prompts to generate false answers from OpenEvidence’s search engine before pharmaceutical executives whose companies account for nearly $20 billion in annual advertising spending.
• This alleged campaign was designed to “undermine OpenEvidence’s reputation and competitive position in the marketplace.”

What they’re saying: OpenEvidence argues that Doximity “attempted to shortcut years of research and development, bypass millions of dollars in investment, and obtain through theft what they lacked the technical expertise.”

• “These companies are staffed with the brightest minds in the world, and are going to have a profound impact on humanity, but only if they can survive,” said OpenEvidence founder Daniel Nadler.
• A Doximity spokesperson said the company could not comment on pending litigation but would “defend these claims vigorously.”

What’s next: OpenEvidence is seeking court orders to block Doximity from using its alleged trade secrets and unspecified financial damages in the lawsuit filed Friday in federal district court in Boston.
