Ultrahuman's Ring Under Fire, A New Unicorn & More

The Tussle Over The Ring

Indian healthtech startup Ultrahuman is at the centre of a patent battle with Oura, the Finnish-American maker of smart rings. A preliminary ruling by the US International Trade Commission earlier this year found that Ultrahuman’s Ring Air infringes several of Oura’s patents.

If the ruling stands, Ultrahuman may be banned from importing its smart ring into the US, its biggest market.

What’s The Matter? Founded in 2019 by ex-Zomato execs Mohit Kumar and Vatsal Singhal, Ultrahuman gained traction globally with its health-focussed wearables. It launched the Ring Air in 2022, only to be slapped by a patent infringement lawsuit by Oura. The Finnish company claims that the Bengaluru startup copied not only its product design but also its tech in connivance with its former employees who leaked trade secrets.

Staring At A Ban? If the patent infringement claims are upheld, Ultrahuman could see a ban on importing and selling its products in the US. With half of its revenues coming from the North American country, the wearables company has much to lose. For context, the US operations helped the company post INR 600 Cr in consolidated FY25 revenues, up 6X YoY.

My Precious: Not willing to give up without a fight, Ultrahuman plans to operationalise its Texas “UltraFactory” by 2025-end to sidestep import restrictions. It also plans to expand into the home health monitoring space, build a preventive blood‑testing suite, and enhance software offerings.

It is looking to bolster retail partnerships in the US, enter new geographies, increase software monetisation to 15% of revenue and experiment with other form factors. With this, the company expects to rake in INR 1,650 Cr in FY26 revenues.

With much at stake, can Ultrahuman survive the Oura fight?

Inc42 Startup Spotlight Can Sthyr’s Zinc-Air Batteries Power India’s Future?

As nations vow to achieve carbon-neutral status, energy storage devices have emerged as the critical engines for this transition. Yet, geopolitical tensions are increasingly complicating access to rare earth metals, which are essential for building these energy storage solutions.

Realising that the world needed an alternative, devoid of these critical metals, Akhil Kongara Gunjan Kapadia and Muhammed Hamdan founded Sthyr Energy in 2024.

An Alternative To Li-ion Batteries? The Chennai-based startup has introduced a zinc-air energy storage device, with a 3.2 kWh battery module. Sthyr claims that its batteries can provide up to 100 hours of battery storage as compared to the eight hours offered by Li-ion batteries. Sthyr claims that the capex on its battery systems stands at $70 per kWh, which it will bring down to $30-40 in two years. In comparison, Li-ion batteries start from $150 per kWh.

Taking On The Giants: While Sthyr has already tested its batteries for 2,000 hours of continuous operation, it aims to increase it to 5,000 hours. The startup is setting up a manufacturing and R&D facility in Chennai with 30 MWh per year capacity, expanding the team, and readying itself for deploying its pilot products within two years.

Sthyr will develop multiple 300 kWh systems in this pilot facility, test them with potential customers, and then go for full-fledged commercial production after three years. With giants like Hindustan Zinc, Exide and Amara Raja on its tail, can Sthyr Energy find success in India’s $169 Bn energy storage market?
