Tail was announced On Thursday it acquired Doublepoint, a startup that specializes in technology that allows users to control wearables through simple, natural movements using a combination of artificial intelligence and biometric data. Financial terms of the deal were not disclosed.
The move paves the way for the company to integrate these controls into its smart rings.
“Doublepoint’s technology helps devices understand small hand movements so interactions are faster and more natural across different interfaces,” Oura wrote in a press release. “When layered on top of Oura’s continuous feel and insights, it enables the creation of new kinds of quiet, useful features that work in the background and make everyday life a little easier.”
The company believes that the next phase of wearable AI will be powered by a combination of voice and gestures, and that the acquisition of Doublepoint will accelerate its vision to power more ambient AI experiences.
The acquisition follows a successful year for Oura and the smart ring market as a whole. The company’s most recent valuation was about $11 billion last fall. Oura has sold 5.5 million rings to date, a significant increase from the 2.5 million reported in June 2024. The company predicts sales will top $1.5 billion in 2026.
The smart ring market itself saw shipments grow by nearly 51% in 2025, according to market researcher IDC, with Oura leading the category, as reported by Bloomberg.
Oura says it is acquiring a team of AI architects and builders from Helsinki-based Doublepoint, including its four founders, noting that they will be central to designing and shipping AI experiences that will define the future of the wearable company.
“As we continue to build the next era of Oura, strategic acquisitions play a key role in accelerating our growth and expanding what our devices and platform can do,” Oura CEO Tom Hale said in the press release. “Welcoming the Doublepoint team to Oura strengthens our bench of world-class talent, reinforces our long-term commitment to grow in Finland, and helps us move even faster to deliver intuitive, human-centric experiences for our members across devices, services and environments.”
Oura’s latest acquisition marks its fourth. The company previously acquired Bay Area-based health monitoring startup Sparta Science, metabolic health startup Veri and digital ID startup Proxy.
