What Vera Health does
Vera is a clinical search engine. When a clinician asks a question, it searches more than 60 million peer-reviewed papers, clinical guidelines, consensus statements and drug labels, then grades the strength of the evidence before giving an answer.
Each claim is colour-coded by how strong its evidence is. According to HIT Consultant, the grading weighs study design, sample size, how recent a paper is and how often it is cited, and claims based only on small case series are flagged in red. Co-founder Maxime Allouch said the company believes there is value in making uncertainty visible.
The tool is free for licensed clinicians and medical trainees. HIT Consultant reported that the company makes money from integrations with healthcare institutions. A product called Vera Spaces lets hospitals add their own protocols and order sets.
Scott M. Silvers, chair of the American College of Emergency Physicians' clinical policies committee, said a large randomised trial and a case report should never carry the same weight. Bernard P. Chang, Vera's chief scientific adviser and vice chair of research in emergency medicine at Columbia University, also backed the approach.
Fast growth with a small team
Vera Health says more than 800,000 clinicians in 190 countries use the tool, up from a few thousand a year earlier. It says about one in four doctors in Spain and Italy and one in seven in France use it.
Citing Appark data, the company says Vera has been the most downloaded clinical app on the App Store and Google Play every month since June 2026, and that its September downloads exceeded those of OpenEvidence and Doximity combined.
The company has 12 employees. HIT Consultant reported that it has grown mainly through recommendations between doctors, with no enterprise marketing budget. It has also partnered with the American College of Emergency Physicians to build the group's clinical policies into the tool.
The company says it handles hundreds of thousands of questions a day and that monthly downloads have more than tripled since February. It says it is HIPAA and GDPR compliant and does not train its models on the patient questions clinicians enter, according to HIT Consultant.
Founders and plans
Vera Health was founded in 2024 at Y Combinator by Taieb Bennani and Maxime Allouch, both MIT graduates and sons of doctors.
The company will spend the money on its clinical evidence infrastructure, expansion into new healthcare markets and closer partnerships with medical societies, publishers and health systems. It says the tool will stay free for clinicians.
