The subscription-free smart ring that turned a food-delivery duo into Oura's fastest-rising rival - and a whole-body health dashboard around it.

In 2015, Mohit Kumar and Vatsal Singhal were routing hot meals across Indian cities with a food-delivery startup called Runnr. Zomato bought it. Four years later the pair reappeared with a stranger question: what if the same obsession with logistics and real-time data could be pointed inward, at the human body?
The answer is Ultrahuman, incorporated in Bengaluru in 2019. It began as a metabolic-health app and a continuous glucose monitor, then hardened into something rarer in consumer health - a company that makes its own precision hardware and stitches it into a single ecosystem. Today its best-known product is a titanium smart ring that reads sleep, heart-rate variability, skin temperature, movement and recovery from the base of your finger.
But the ring is only the visible tip. Ultrahuman now sells the M1 continuous glucose monitor, the Ultrahuman Home indoor environmental sensor, and Blood Vision, a service that tracks more than 100 blood biomarkers over time. Each feeds the same app, and the app's job is not to show you more numbers. It is to tell you which one to act on this morning.
That editorial instinct - what to ignore - is the actual product. A body generates far more data in a day than any person can absorb. Ultrahuman's pitch is that the winning wearable is the one that hands you a nudge small enough to follow before you talk yourself out of it.
At its core, Ultrahuman measures the signals that predict how well you will feel and perform - sleep quality, recovery, metabolic response to food, cardiovascular strain - and translates them into plain guidance. The Ring AIR and newer Ring PRO handle continuous passive tracking; the M1 CGM adds a real-time window into blood sugar; Blood Vision adds the deeper, quarterly bloodwork picture; Ultrahuman Home connects the bedroom's air, light and noise to the sleep score it affects.
Its customers span three overlapping groups: health-conscious consumers who want to sleep and recover better, athletes chasing marginal gains, and people managing metabolic risk who want to see - literally - how a meal moves their glucose. The company reaches them across more than 100 markets, through its own site and 150-plus retail outlets including premium department stores.
The problem it attacks is old: most people learn about their health only when something breaks. Annual checkups are snapshots; symptoms arrive late. Ultrahuman's answer is continuous, non-invasive measurement that makes prevention a daily habit rather than an emergency response - and, crucially, does it without asking users to become data analysts.
There is also a quieter problem it solves - trust. By selling hardware outright and not renting back your own metrics behind a paywall, Ultrahuman removes the friction that makes some people abandon health trackers within weeks.
"Smart rings will become a computer on the body - with the ability to at least micro-think."

Launched 2022Third-generation ring with dual-core processor and up to 15 days of battery (45 with the case). Built for more durable, higher-performance tracking.
Launched 2026Continuous glucose monitoring that produces a Metabolic Score and real-time nutrition guidance - see how food, sleep and exercise move your blood sugar.
Launched 2021Indoor sensor for air quality, temperature, humidity, noise and light - linking your environment to the sleep and recovery scores it shapes.
Launched 2025Blood-biomarker testing across 100+ markers with longitudinal tracking, available in the US, India, UAE and Saudi Arabia.
Launched 2025An app layer for the ring - some free, some paid - including AFib detection, Cycle & Ovulation Pro and pregnancy insights.
Launched 2024The most-cited difference is commercial: Ultrahuman's rings carry no mandatory subscription, a pointed contrast with market leader Oura, which gates insights behind a membership. Buy the ring once, keep the data. In a category where churn is the enemy, that is a strategy, not a slogan.
The second difference is scope. Rivals mostly sell one device. Ultrahuman sells an ecosystem - ring, CGM, blood test, home sensor - designed to speak one language, so a poor night's sleep, an air-quality dip and a glucose spike can be read together rather than in separate apps.
The third is manufacturing. Where most hardware brands ship from Asia, Ultrahuman is opening UltraFactory in Texas to build rings on US soil, funded by a discipline unusual in its peer group: profitability. That lets it make long-term factory bets competitors can't easily match.

"Our ability to make long-term manufacturing investments, supported by our profitability, is unique in the smart ring market."
Backers include Nexus Venture Partners, Blume Ventures, Steadview Capital, Alpha Wave and Zomato founder Deepinder Goyal. Series C reported at ~Rs 400 crore; a Premji Invest lead reported in press was denied by the company. Secondary trackers cite a ~$575M valuation (unconfirmed).

A health-tracking ecosystem: the Ring AIR and Ring PRO smart rings, the M1 continuous glucose monitor, the Ultrahuman Home environmental sensor and the Blood Vision biomarker test - all unified in one app.
No. Ultrahuman sells its rings on a one-time purchase model with no mandatory subscription. Some premium PowerPlugs apps and consumables like CGM sensors and blood tests are paid separately.
It was founded in 2019 in Bengaluru by Mohit Kumar (CEO) and Vatsal Singhal, who previously built the food-delivery startup Runnr, later acquired by Zomato.
Ultrahuman is the second-largest smart-ring maker by units sold. It differentiates with a subscription-free model, a broader device ecosystem, and in-house US manufacturing, and aims to challenge market leader Oura.
