Ultrahuman is a metabolic-health wearables company best known for the Ultrahuman Ring AIR, an AI-powered smart ring competing directly with Oura. The platform tracks sleep, heart-rate variability, body temperature, activity and recovery, and uses AI to translate that data into personalized insights, scores and coaching. Beyond the ring, Ultrahuman builds a broader ecosystem including continuous glucose-monitoring (M1) and home health products, positioning itself as a metabolic-fitness platform rather than a single device. Founded in 2019 and headquartered in Bengaluru with operations in the US and Europe, Ultrahuman has raised more than $100 million across multiple rounds. Its $35 million Series B in March 2024 was co-led by existing investors Blume Ventures, Steadview Capital and Nexus Venture Partners, with participation from Alpha Wave Global and Zomato founder Deepinder Goyal. The company launched the Ring Pro in the US after receiving market clearance, marking a comeback against Oura.
