Ultrahuman makes health-tracking wearables and metabolic health tools built around a smart ring, blood testing, glucose monitoring, and connected home sensors.
Now the Ultrahuman smart ring story has a lot more money behind it. The Bengaluru company has closed a Series C round of around ₹400 crore, or about $48 million. The problem it’s trying to solve is simple enough: health data is scattered, hard to interpret, and too clunky for most people to use every day. Founded in 2019 by Mohit Kumar and Vatsal Singhal, Ultrahuman is trying to turn that mess into a single always-on health stack — and this round comes just as it tries to get back into the US after a bruising patent fight with Oura.
One wrinkle still hangs over the deal. One person said Premji Invest led the round, but Kumar pushed back and said Ultrahuman has “not raised from Premji,” then declined to say more. It tells you this financing is real, but some cap-table details still aren't fully settled in public.
What is the Ultrahuman smart ring and how does it work?
The short version: Ring PRO is Ultrahuman’s third-generation health-tracking ring. It collects passive biometric data through the ring, syncs that data through the app, and translates it into scores, prompts, and longer-term guidance. It tracks sleep, recovery, movement, stress, heart rhythm and other markers. Then it layers those signals into features like Sleep Index, Dynamic Recovery, Stress Rhythm, Movement Index, and Ultra Age.
What makes the product more interesting now is that it’s no longer just a ring. If a user is inside the wider Ultrahuman system, Jade — the company’s new biointelligence layer — can combine ring data with 120+ Blood Vision biomarkers, M1 CGM glucose trends, and data from Ultrahuman Home. That means the user isn't stuck hopping between dashboards and guessing what matters. They can ask natural-language questions and get recommendations back.
The hardware changes are pretty concrete too. Ring PRO has up to 15 days of battery life and stores up to 250 days of data on the ring itself. It uses a redesigned heart-rate sensing architecture and runs on an upgraded dual-core processor with on-chip machine learning. The new PRO Charger adds up to 45 days of extra battery life and stores up to a year of ring data. It also supports Qi charging and includes a “Find My Case” feature.
And that’s really the before-and-after pitch. Before, serious health nerds had to piece together sleep data, heart metrics, blood markers, and glucose trends from separate products. After, Ultrahuman wants one ring-led system to do the stitching. Ambitious? Yes. But it’s a real product thesis, not vague wellness branding.
Who founded Ultrahuman and how did the company get here?
The founding story
Ultrahuman was started in 2019 by Mohit Kumar and Vatsal Singhal in Bengaluru. The company first built around metabolic health and performance tracking, then expanded into hardware and a broader consumer health platform. That arc matters because Ultrahuman didn’t begin as a fashion-first wearable brand. It began with biomarker-heavy health optimization, and the ring became the most scalable way to package that idea.
Why Mohit Kumar had market fit
Kumar wasn’t new to building fast-moving consumer tech companies. Before Ultrahuman, he was chief operations officer of Zomato’s food delivery business until 2019, and before that he co-founded Runnr with Singhal — a last-mile and food delivery startup that later folded into Zomato in 2017. He’s also a graduate of PES Institute of Technology in Bengaluru. That doesn't automatically make someone a wearable-tech founder. But it does mean Kumar had already lived through scale, operations, logistics, and a startup exit before trying to build hardware.
What Ultrahuman has shipped so far
Ultrahuman has been steadily widening the product set. Ring Air launched in 2022. Ring PRO is positioned as the performance-oriented upgrade, while Ring Air stays in the lineup for people who care more about comfort and lighter wear. Kumar’s own summary was blunt: Pro is for performance with 15-day battery life, Air is for comfort with 5-6 day battery life. Ring PRO is already on sale in India, Europe, the UAE, and Australia. The company has also expanded into blood testing and home health devices. That helps explain why its product roadmap now stretches beyond rings.
The Series C and the US reset
This new round lands at a very specific moment. Ultrahuman has already raised more than $60 million in equity from Rainmatter Capital, Nexus Venture Partners, Blume Ventures, Alpha Wave Incubation, Steadview Capital, and angel investor Deepinder Goyal. In November 2025, it also took ₹100 crore in venture debt from Alteria Capital. The fresh Series C money is expected to fund 3 things: a US return with the redesigned Ring PRO, expansion into new geographies, and new wearables — including a wristband-style product and new home lines.
That US return isn’t just a sales push. It’s a legal comeback. In August 2025, the US International Trade Commission ruled in favor of Oura in a patent case involving Ultrahuman and RingConn, then exclusion and cease-and-desist orders took effect on October 21, 2025, blocking imports and sales tied to the older Ring Air design. The new Ring PRO has been redesigned specifically to avoid the battery-integration and form-factor issues at the heart of that dispute, and The CapTable reported that Ultrahuman has now received approval to bring the redesigned ring back to the US.
Where it sits against Oura, RingConn, and the old alternatives
Oura is still the company to beat. It raised a $200 million Series D in November 2024 at a $5.2 billion valuation, and by May 2024 it had sold more than 2.5 million rings. That’s the scale benchmark Ultrahuman is chasing. RingConn is another direct smart-ring competitor, and it was dragged into the same patent fight. Then there are the older alternatives — smartwatches and fitness bands. They offer broader notifications and screens but still lose on comfort, sleep wearability, and passive data capture for a lot of users.
Ultrahuman’s differentiation is pretty clear. It’s pushing battery life and a performance-first ring. It also wants deeper data integration across glucose, blood and home signals, plus a more complete health-data layer rather than just a hardware accessory. Investors aren't just betting on a ring. They're betting that a ring can become the entry point into a broader personal-health subscription and device stack.
Why does Ultrahuman smart ring funding matter right now?
Because this round isn’t about survival. It’s about whether Ultrahuman can turn a legal setback into a product reset.
If Ring Air had stayed blocked in the US with no clear redesign path, the company’s global ambitions would’ve looked a lot thinner. The US is still the most important premium wearables market for category-defining brands, especially in health tracking. Getting Ring PRO through that bottleneck gives Ultrahuman a second shot at the one market where Oura already has brand gravity, distribution muscle, and consumer familiarity.
There’s also a roadmap signal buried in the use-of-funds plan. A wristband form factor and new home lines suggest Ultrahuman doesn’t want to be trapped inside a single-device story. That’s smart. Hardware categories can go cold fast. A multi-device health stack is harder to build, but it also gives the company more shots.
And honestly, that’s probably what investors are buying here. Not just a prettier ring. A wider platform.
How big is the market for an Ultrahuman smart ring?
The category is no longer niche. MarketsandMarkets estimates the North America wearable technology market will grow from $34.1 billion in 2025 to $69.1 billion by 2030, a 15.2% CAGR. Smart rings are still a small slice of that total, but they sit inside one of the fastest-moving parts of consumer health tech: passive, always-on, lower-friction monitoring.
That timing helps Ultrahuman. Consumers have gotten a lot more comfortable with continuous health data. They also want devices that don’t feel like tiny smartphones strapped to their bodies. That’s why screenless wearables are getting real attention now — less distraction, more wear time, better sleep tracking, and fewer charging headaches when the hardware is done right.
AI is part of the timing too. People don’t just want more data anymore. They want interpretation. Jade is Ultrahuman’s answer to that shift, and Oura has already shown there’s real appetite for smart rings. So the market tailwind is real. But tailwinds don’t guarantee a win. Execution does.
Ultrahuman’s next chapter comes down to one thing: can it turn the Ultrahuman smart ring from a strong alternative into a category leader with real US momentum? The funding gives it the chance. The redesigned Ring PRO gives it the opening. What to watch next is simple — whether the US relaunch sticks, and whether the company can make that wider health stack feel indispensable instead of overbuilt.

FAQ
What is Ultrahuman raising in its latest funding round?
Ultrahuman has closed a Series C round of around ₹400 crore, or roughly $48 million. One source said Premji Invest led the round, but Mohit Kumar publicly denied that specific detail and said the company had “not raised from Premji.”
How does Ultrahuman Ring PRO differ from Ring Air?
Ring PRO is the higher-performance model, with up to 15 days of battery life, more computing power, and a redesigned architecture aimed at more durable health tracking. Ring Air, which launched in 2022, stays positioned as the lighter and more comfort-first option with about 5-6 days of battery life.
Who founded Ultrahuman?
Ultrahuman was founded in 2019 by Mohit Kumar and Vatsal Singhal. Before that, the pair had already built Runnr, and Kumar later ran delivery operations at Zomato until 2019 — which gave him a pretty unusual mix of startup and scale-execution experience for a hardware founder.
Is the smart ring market big enough for Ultrahuman to matter?
Yes — if the company executes well. North America’s wearable-tech market alone is projected to grow from $34.1 billion in 2025 to $69.1 billion by 2030, and Oura has already sold more than 2.5 million rings, which shows consumer demand for the form factor is real rather than experimental.
