Company Description

OpenEvidence operates an AI-powered medical information platform used by healthcare professionals to access journal content, guidelines, and other medical information through natural-language search. The platform is an official content partner of publications including the New England Journal of Medicine and The Journal of the American Medical Association. According to the company, its user base includes more than 500,000 healthcare professionals each month. Founded in 2021, OpenEvidence launched during the Mayo Clinic Platform Accelerate program and is backed by investors including Sequoia and Google.

The company plans to expand from an information retrieval tool to a platform that supports the creation of new medical evidence, partly by providing feedback to organizations like the American Diabetes Association (ADA) on how guidelines are used. Recent announcements include partnerships to integrate content from the American Academy of Family Physicians (AAFP) and the American College of Emergency Physicians (ACEP). OpenEvidence also launched a HIPAA-secure application, OpenEvidence Dialer, which allows clinicians to call patients from their personal devices while displaying their hospital's caller ID and generating clinical notes from the calls.
