OpenEvidence is a startup that has developed an AI chatbot to help doctors search for clinical evidence. The firm raised $250 million, doubling its valuation to $3.5 billion[1]. The tool is already used by 430,000 doctors in the USA and 40% of all American doctors[1][2]. It serves more than 8.5 million consultations per month and recorded 17 million AI clinical consultations from verified doctors in October[1][2]. OpenEvidence is not a diagnostic system, therefore it does not require FDA approval and enables rapid deployment in practice[1]. It helps doctors quickly find relevant information from millions of studies, analyze drug interactions and recommend tests[1]. This year, more than 100 million Americans will be treated by doctors using OpenEvidence[2]. The product is free for healthcare professionals[2].
