Ultrahuman Ring (Air / Pro) at Global

Ultrahuman, founded in 2019 in Bengaluru, India by Mohit Kumar and Vatsal Singhal, both previously of Runnr, makes the Ring Air and the newer Ring Pro biometric smart rings, recorded in the biometric form factor, on a Series B of $35 million at roughly a $125 million valuation in March 2024 with a strong India-market base and global availability. Its rings pair heart-rate, heart-rate-variability, temperature, sleep, and recovery sensing with modular PowerPlugs for metabolic and circadian insights and a paid atrial-fibrillation plug, with no mandatory subscription for core tracking.

It is the load-bearing verified-versus-claimed exemplar at company-availability scope: in Oura's International Trade Commission case over patent 11,868,178, a final determination around August 22, 2025 found all asserted claims valid and infringed by Ultrahuman, issuing a limited exclusion order and cease-and-desist orders that took effect on October 21, 2025 after the sixty-day Presidential review concluded without a veto, and Ultrahuman's appeal to the Federal Circuit is pending with its emergency stay denied by both the ITC and the court, so its Ring Air's US market access was legally blocked even though the product and its AI exist and ship globally. Ultrahuman re-entered the US not via Texas-made Ring Airs but via a redesigned Ring Pro whose unibody architecture is engineered so the patent does not apply, clearing US Customs around March 24, 2026 and reopening US pre-orders, so the Ring Air is recorded as US-excluded with an appeal pending while the Ring Pro is US-available.

On FDA status, its atrial-fibrillation detection is powered by the third-party FDA-cleared FibriCheck software whose vendor holds the clearance rather than Ultrahuman's ring, gated behind a paid plug, so headlines calling the ring FDA-approved overstate it, and its cumulative funding figures beyond the verified Series B and its self-published validation studies are not independently verified. A correction worth recording: the co-founder is Vatsal Singhal, not Vatsal Kumar.
