Ultrahuman and Abu Dhabi's health center will spend two years validating a biological-age model

A UAE resident who eventually opens TAMM or Sahatna to see a health age will be looking at a number ^[16] from a model built on data from customers whose typical age is 25 to 43 ^[3]. The company says the model will eventually reach people across the country ^[15]. CEO Mohit Kumar told TechCrunch that working with a government lets Ultrahuman apply its algorithms to a far broader population than its own customer base ^[14].

The pitch and the paperwork are at different stages. The pitch is national scale: the company calls the Abu Dhabi work its first step toward deploying a health algorithm at that level ^[6]. The paperwork is a memorandum covering two years of research and clinical validation ^[2]. Kumar said the broader rollout will happen in phases but did not provide a timeline ^[17].

Kumar described the company's priorities plainly. "If you look at Ultrahuman as a company, we obviously have the Ultrahuman Ring, which is a way to acquire data from the human body," he told TechCrunch ^[7]. The model's design matches that. It is meant to be wearable-agnostic, taking data from rings, wrist-worn devices, straps and patches alongside clinical biomarkers ^[9].

The base the company draws on today is its ring owners. Ultrahuman has operated in the UAE for nearly five years and, according to Kumar, sees about 25% higher retention there than in its other markets ^[11]. Retention is a measure of people who bought a ring, and a national program would also reach people who did not.

Kumar stressed that the model will not be trained on data from the UAE. "We will deploy an algorithm on the UAE data," he said ^[18]. He added that Ultrahuman will not have access to personally identifiable information through the program ^[20]. In our view, that puts the weight on the validation years. A model fitted to 25-to-43-year-olds has to show it holds for the rest of the age range without being refit on local data.

Kumar said he knows of no other company collaborating with the Abu Dhabi authorities on the health age model in particular, and he declined to comment on the scope of Oura's work there ^[13].

For any vendor health score headed to a public platform, we'd sort it with two questions. The first is whether the model was built on people like those who will see the number. The second is whether it has been checked on local data before anyone sees an output. Built on similar people and checked locally: roll out. Similar people, not yet checked: run an opt-in pilot. Different people, checked locally: roll out with age bands marked where the check was thin. Different people, not yet checked: keep it in research.

On Kumar's description, Ultrahuman's model starts in that last box. Its typical users are 25 to 43 ^[3], it is not trained on UAE data ^[19], and the validation is still ahead ^[2]. Two years of validation could move it to the checked column. The age mix of the people it was built on stays as it is, because the model will not be retrained on UAE data ^[19].
