K Health

A comparison idea, not a prediction idea

Instead of trying to "guess" a diagnosis, the system holds a structured conversation with the patient about their symptoms. It then shows what the course of care looked like for people similar to them, by age, sex, medical history and symptoms, in databases of detailed medical records. The company was founded in 2016 by Allon Bloch, Ran Shaul, Israel Roth and Adam Singolda (CEO of Taboola). Bloch built the engine on historical data from Maccabi, an Israeli health maintenance organization, and later also on data from Mayo Clinic.

What the tool actually does: it shortens intake

The tool's practical job is to shorten and streamline intake. The patient gives the initial information at their own pace, and the doctor joins the conversation when the picture is already laid out. The company sells this to health systems and insurers, not only to individual consumers. In each of these sales channels, the tool sits on one side of a line that regulators watch closely. Digital therapeutics is software that is itself the treatment, and it must prove clinical effectiveness with evidence. An intake engine that organizes information for the doctor makes no such claim and is not required to.

What K Health itself publishes about its partnerships

The company's official press page, khealth.com/press, records a series of partnerships with health systems: Cedars-Sinai (the virtual care service Cedars-Sinai Connect, 2023), Mayo Clinic (an "AI Physician" mode available on the Mayo Clinic platform, May 2025), Northwell Health (November 2025), Hartford HealthCare (an expansion into specialty telehealth, June 2026), Novant Health (July 2026) and Atlantic Health (August 2026). The page also lists studies done with Cedars-Sinai and Mayo Clinic, including a study published in Annals of Internal Medicine in 2025 that compared the accuracy of the AI's clinical recommendations with those of doctors.

What a comparative study found

A study published in BMJ Open in December 2020 compared eight symptom-checker apps with family doctors on 200 clinical vignettes. K Health offered a suggestion in 74.5% of cases, and the correct diagnosis was among its top three suggestions in 36% of cases, compared with an average of 82% for the doctors. The study was funded by Ada Health, the maker of a competing app tested in it, and most of its authors worked for that company. It is not a tool approved for independent diagnosis, and the clinical conclusion stays with a doctor. Someone reading about products like this may get the impression that they replace a visit to the doctor. They do not.

The business model: B2B2C, not direct to consumer

Over the years the company has raised about $380 million. Its headquarters are in New York, but its founders and development center are Israeli. Its main business value lies in working with existing health systems rather than selling directly to consumers. This model puts a supervising doctor into the process from the start, which reduces the risk that a user will rely on an answer no professional has seen.
