Ultrahuman has closed a Series C funding round of about Rs 400 crore ($48 million), according to two people with direct knowledge of the deal. The round comes at a key time for the company as it prepares to re-enter the US market with a redesigned version of its smart ring.

Ultrahuman Secures New Funding to Launch Redesigned “Ring Pro” and Target US Market Return

One source said the round was led by Premji Invest. However, Ultrahuman’s founder and CEO, Mohit Kumar, denied this and said the company has not raised funds from Premji. He did not share more details.

A senior executive at Ultrahuman said the fresh capital will support the company’s return to the US. It will also help expand into new markets and build new product lines. These include devices in a wristband format and products for the home.

The executive added that the company may raise more funds in the coming months. Details about other investors in the current round remain unconfirmed.

So far, Ultrahuman has raised over $60 million in equity funding. Its backers include Rainmatter Capital, Nexus Venture Partners, Blume Ventures, Alpha Wave Incubation, and Steadview Capital. Angel investors such as Deepinder Goyal have also backed the company. In November 2025, Ultrahuman raised Rs 100 crore in venture debt from Alteria Capital.

The new funding comes after a legal setback in the US. Ultrahuman’s earlier product, Ring Air, was barred from the market after a patent ruling in favor of Oura. The case focused on design patents to the physical structure of smart rings.

In August, the US International Trade Commission ruled that Ultrahuman had violated Oura’s patents. The ruling led to import bans and restrictions on sales and marketing in the US starting October 21. The case also involved China-based RingConn.

Now, Ultrahuman says it has addressed those concerns with its new product, Ring Pro. The company recently received approval to bring the redesigned ring to the US, according to a senior executive. This marks a major step in its plan to compete in a key market.

In an internal note to employees, Kumar described the approval as a breakthrough. He said it brings the company closer to becoming a global leader in the smart ring space.

Powering Up with Ring Pro While Sidestepping Legal Hurdles

Ring Pro is positioned as a performance-focused upgrade to Ring Air, which launched in 2022. The two products will co-exist. Each targets a different user need.

Ring Air focuses on comfort. It offers a lightweight design and a battery life of five to six days. Ring Pro, in contrast, focuses on performance. It offers up to 15 days of battery life and higher computing power.

The redesign of Ring Pro goes beyond features. It also aims to avoid fresh legal risks. According to the executive, the company rebuilt the device from scratch to ensure it does not infringe on Oura’s patents.

The earlier dispute centered on how the battery was placed within the ring’s circular body. Oura argued that Ultrahuman’s design overlapped with its patented architecture. The new design changes that internal structure.

The executive said the company reviewed every point raised in Oura’s legal filings. It then adjusted the design to address those concerns. The goal was clear: avoid another legal challenge while keeping product performance high.

With fresh capital, a redesigned product, and renewed access to the US, Ultrahuman is entering a new phase. The next few months will show whether it can turn this reset into long-term growth.
