Oura Signs Tennis Stars, Viome Acquires Circulate, Clair Partners with Mayo Clinic

Listen On:

Health companies are moving beyond collecting data to making it useful — in the clinic, in treatment, and in everyday performance.

Oura bets on sports culture

Oura signed tennis stars Coco Gauff and Taylor Fritz as brand ambassadors ahead of the US Open, adding to partnerships with soccer stars Harry Kane and Declan Rice.

The strategy extends beyond celebrity marketing.

Oura is putting its data into the routines of athletes who have to manage travel, sleep, recovery, training, and competition across long seasons.
Leveraging identity and performance, Oura is positioning the ring as part of how elite athletes operate, while using powerful relationships to reach larger sports audiences.

As wearable hardware becomes harder to differentiate, distribution, brand, and cultural relevance become increasingly important competitive assets.

Viome expands preventative health

Viome acquired Circulate Health, the largest US provider of therapeutic plasma exchange (TPE), bringing a treatment capability into a business built around diagnostics, nutrition, and preventative health.

The deal creates Viome Pro, combining Circulate’s network of more than 200 clinics with Viome’s molecular testing and data infrastructure.
While blood testing startups add panels and scan clinics replace checkups, preventative consumer health is still missing the treatment layer.

The strategic bet is straightforward: own more of the journey from measurement to intervention.

Clair taps clinical hormone data

Clair Health partnered with Mayo Clinic Platform_Accelerate to validate its continuous hormone and symptom monitoring platform using millions of longitudinal, de-identified clinical records.

Planning to launch its wearable in November, the company is testing everything from cycle phase and ovulation to irregular cycles, hormone-symptom patterns, and the perimenopausal transition.
The Mayo relationship will help Clair turn wearable data into something clinicians can trust by interpreting which signals matter, how they relate to a patient’s history, and whether those interpretations hold up across different populations and conditions.

For Clair, clinical validation becomes part of the product — and potentially the bridge from a consumer wearable into clinical decision-making.
