San Francisco, October 27, 2026 / PRNewswire / -- Vera Health indicates that just a year ago, only a few thousand clinicians were using its platform, but now that number has exceeded 800,000, and most users discovered the platform through referrals from colleagues. The company claims that since June, Vera has been the clinical application with the highest downloads globally each month, surpassing App Store and Google Play. In September alone, its downloads exceeded the sum of OpenEvidence and Doximity, and the monthly downloads have more than tripled compared to February.

Vera Health states that with only 12 employees, the company has reached clinicians in 190 countries, where approximately one in every four doctors in Spain and Italy uses the platform, which is largely due to word-of-mouth. Vera Health is a clinical AI search engine that claims to be able to reason like clinicians, helping doctors to find and evaluate medical evidence within seconds.

Vera Health announced the completion of a $28.5 million Series A financing on the same day, led by Threshold Ventures, with Mantis VC and SV Angel also participating in the round. Existing investors Y Combinator and Gradient continued to increase their investment in this round, bringing the company's total financing to $32 million. The company stated that this funding will accelerate its mission to narrow the gap between "what is known in medicine" and "what each patient actually receives in treatment."

The company stated that just a few months after completing its Series A financing, Vera now has a daily active user base that exceeds the monthly active user base at the time of financing. The number of questions clinical doctors pose to Vera has also increased from several thousand per day to hundreds of thousands per day today.

Vera Health, co-founder, and Taieb Bennani stated: "Clinicians are the most outstanding data scientists I have ever met. They can make judgments in just a few seconds, based on more evidence than any human could possibly read in their entire lifetime. The secret to creating products for them is to truly immerse ourselves in their problems in a way that no one else does. Everyone in our team is either a clinician themselves, or, like Maxime and me, we are children or siblings of clinicians. This passion is reflected in every detail of our product; when you build a product with such dedication, it speaks for itself, and clinicians will share it with their colleagues. We don't have the largest team, nor do we have the most money. What we do have is people who care most about getting things right."

What is the difference between Vera Health and the general-purpose AI tool?

Vera Health indicates that clinical AI is increasingly being used to assist doctors in dealing with complex medical issues, but the ability to generate answers that sound accurate does not necessarily mean that the research behind it is reliable. In the field of medicine, a new scientific paper is published approximately every 20 seconds. Chatbots are designed to sound confident, while Vera is designed to pursue accuracy and to be honest when there is insufficient evidence.

The company stated that doctors need to continuously keep up with the rapidly expanding body of research literature, interpret guidelines, assess treatment plans, and make decisions for individual patients, sometimes all within just a few seconds.

Vera Health indicates that the approach is to first find evidence before writing an answer. Their technology searches through over 60 million peer-reviewed papers, clinical guidelines, consensus statements, and drug labels, and evaluates the sources based on study design, evidence level, cohort size, timeliness, journal quality, and citation impact. Each conclusion is linked to the corresponding research, and the strength of the existing evidence is indicated by color. Sometimes this color may be red. For certain rare diseases, there may be no large randomized trials or comprehensive guidelines to support them; instead, there may only be small case series or even reports from a single patient. Vera Health means that they present these studies while clearly showing their limitations, allowing doctors to decide for themselves how much weight to assign to these findings.

Vera Health, co-founder, and Maxime Allouch stated: "Medical knowledge is updated too rapidly for any single clinician to keep up with all of it, and general-purpose AI tools might make uncertain evidence sound like definitive conclusions. Unlike other tools, we believe that it is valuable to make uncertainty visible. The level of evidence affects the content of Vera searches and writings, while clinicians bring in patients, contexts, and their own judgments."

Vera Health indicates that its methodology was developed through collaboration with doctors who evaluate medical evidence and participate in writing guidelines followed by other clinicians. By partnering with the American College of Emergency Physicians (ACEP), this platform has integrated the clinical policies of ACEP along with attribution of sources, directly incorporating the guidance of these medical societies into the clinical research workflow.

The chairman of the Clinical Policy Committee of the American College of Emergency Physicians and former director of emergency medicine at Mayo Clinic, Scott M, a Doctor of Medicine, stated: "In medicine, not all evidence is of equal importance. Large randomized trials and case reports should by no means carry the same weight, but most AI tools mix them together to produce equally confident answers. The level of evidence is the foundation upon which we write each guideline, and Vera Health is built on this very principle."

For Vera Health, the Chief Scientific Advisor, and Bernard P, the Deputy Director of Research at the Department of Emergency Medicine at Columbia University, the importance of clinical evidence is also reflected in how doctors assess patients.

Chang states: "During my most recent emergency shift, I treated a young woman who was coughing and experiencing shortness of breath. These symptoms are easily attributed to common respiratory diseases. The evidence presented by Vera Health made me start to worry about pulmonary embolism—a potentially life-threatening blood clot in the lungs—and prompted me to broaden my assessment. What truly interests me is not whether AI can just provide an answer, but whether it can reliably present evidence that challenges our initial assumptions and improves clinical reasoning. This is precisely what we are strictly evaluating in the academic medical centers where we are actually practicing medicine today."

Vera Health indicates that her clinical advisors also include Christopher Baugh, who is the Deputy Director of Clinical Affairs in Emergency Medicine at Brigham and Women's Hospital and an Associate Professor of Emergency Medicine at Harvard Medical School, holding a Doctor of Medicine degree and a Master of Business Administration. Members of her clinical committee include leading physicians affiliated with Mayo Clinic, Yale University, Harvard University, Columbia University, and the University of Pennsylvania.

Why has Vera Health been able to achieve rapid growth in the international market?

Vera Health indicates that Bennani and Allouch grew up in families of doctors and were initially developed for their respective fathers' Vera Health. This product, which initially had only two users, has now grown into a platform serving hundreds of thousands of clinicians, with doctors posing hundreds of thousands of questions every day. The company claims that its international growth reflects an approach built around a core medical reality: medical knowledge is global, but clinical practice is localized.

The company gave an example that emergency doctors in France may follow different treatment guidelines from those in the United States; oncologists may need to conduct a thorough evaluation of existing research when reviewing complex cases, whereas emergency doctors need to get concise answers within seconds. Even among doctors in the same specialty, they may follow different procedures depending on the institution they work for.

Vera Health indicates that it addresses these differences by prioritizing the presentation of locally relevant guidelines, while also incorporating global medical research findings. Through Vera Spaces, healthcare systems can also integrate their own clinical processes and pathways into the platform alongside national guidelines and international medical literature.

Allouch indicates: "Medicine is a global endeavor, yet most of the tools in our field are designed for a single region. From day one, we have pursued an international approach, because only with a global perspective can we truly understand what localization entails."

According to company data, this method has helped Vera Health expand in Europe: approximately one in every four doctors in Spain and Italy uses the platform, while in France, it is about one in every seven doctors. Vera Health indicates that the company achieved this international coverage with a small team size, and the product was mainly discovered through word-of-mouth among clinicians.

What will Series A financing support next?

Vera Health indicates that this financing will support its further construction of clinical evidence infrastructure, expansion into more medical markets, and deepening cooperation with medical societies, publishers, and healthcare systems. The company will continue to invest in locally relevant clinical guidelines, as well as tools that enable healthcare institutions to integrate their medical knowledge into the platform.

Gradient Partner Andrew Brackin states: "In the field of healthcare, trust is earned, not bought." Vera The adoption rate among clinicians worldwide demonstrates what Taieb and Maxime have created. By combining the most rigorous medical evidence with an understanding of each doctor's specialty, processes, and practice environment, Vera connects global medical knowledge with the actual delivery of healthcare services. We believe that this creates a tremendous opportunity to improve global health.

Threshold Ventures, co-founder and managing partner, and Emily Melton stated: "What makes Vera stand out is that it starts with evidence, rather than just providing an answer. It helps clinicians find and evaluate the research behind a particular decision, making its strengths and limitations clearly visible. By bringing this evidence to the clinical setting, Vera becomes a trustworthy layer of clinical intelligence, rather than just another AI tool."

Vera Health indicates that as the accessibility of medical evidence and local relevant clinical guidelines expands, the platform will continue to be freely available to certified clinicians and medical trainers around the world.

According to research published in Journal of the Royal Society of Medicine, it takes an average of 17 years for new medical knowledge to be incorporated into routine clinical practice. Vera Health states that their goal is to reduce the time doctors spend searching for and evaluating this knowledge, bringing relevant evidence closer to the point in time when clinical decisions are made.

Bennani represents: "Our mission is to bridge the gap between what is known in medicine and the actual treatment received by each patient. Today, this gap is measured in years. We hope to measure it in seconds."
