Ultrahuman closes Rs 400 Cr Series C round

Ultrahuman has closed a Series C funding round of around Rs 400 crore ($48 million), according to two people familiar with the matter.

The round is led by Premji Invest, one of them said. However, Mohit Kumar, Founder and CEO of Ultrahuman, denied this, stating that the company has “not raised from Premji.” He declined to comment further.

A senior company executive said the proceeds will be used to support the company’s return to the US market with its redesigned Ring Pro, expand into new geographies, and develop new wearable categories.

“Something in the wristband form factor, new home lines are some of them,” the executive said, adding that more funding may follow in the coming months.

YourStory could not independently confirm details of the lead and other participating investors.

So far, Ultrahuman has raised over $60 million in equity funding from investors including Rainmatter Capital, Nexus Venture Partners, Blume Ventures, Alpha Wave Incubation, and Steadview Capital, along with angels such as Deepinder Goyal. In November 2025, it also secured Rs 100 crore (~$11 million) in venture debt from Alteria Capital.

The Series C comes at a crucial moment for the company as it prepares to re-enter the US market with its redesigned smart ring, months after its Ring Air was barred following a patent ruling in favour of rival Oura.

On Friday, The CapTable reported that Ultrahuman received official approval to take its redesigned ring to the US, according to a senior executive at the company.

In an internal message to employees reviewed by The CapTable, Kumar described the development as a major breakthrough for Ultrahuman’s ambitions in the US and a key step towards it becoming a market leader in the coming years.

Ultrahuman has positioned Ring Pro as a performance-focused upgrade to its earlier Ring Air, launched in 2022. The new device is currently available in India, Europe, the UAE, and Australia.

While Air prioritises comfort and lightweight wearability, the new device focuses on longer battery life and greater computing power.

“Pro is performance (15 days battery life), Air is comfort (5-6 day battery life and the world’s lightest ring). Both will continue as people look for different things,” Kumar told The CapTable.

Behind these upgrades lies another objective: ensuring the new device does not risk fresh legal challenges from Oura.

In August, the US International Trade Commission ruled in favour of Oura in a patent dispute against Ultrahuman and China’s RingConn. 

The case centred around Oura’s design patents related to the ring’s form factor—its physical shape and structure. 

The trade commission found Ultrahuman in violation, and issued exclusion orders (banning imports) and cease-and-desist orders (blocking sales, marketing, and distribution), effective October 21.

“The entire design of Ring Pro has been done from the ground up to make sure there is no patent infringement,” said the senior Ultrahuman executive quoted earlier. “The major concern was that we didn’t want to get attacked by Oura again.”

According to the executive, the dispute with Ring Air centred around how the ring’s battery was integrated within its circular casing. 

Oura had argued that Ultrahuman’s ring design overlapped with its patents governing the architecture of smart rings.

“This time around, the company has gone over and beyond to make sure that none of those issues remain within the ring’s closed system,” the executive said. “Whatever the patents were, we have been able to overcome all points which were part of their (Oura’s) legal documentation.”
