Oura, the producer of wearable health rings, has confidentially filed to IPO in New York.
The company announced earlier this week that it has filed IPO paperwork with the US Securities and Exchange Commission. It didn’t provide information about the number of shares to be offered or the price range.
The Finnish company, which was valued at around $11bn in October, makes wearables that allow users to track their biometric data — like sleep, health and fitness — in pursuit of leading longer and healthier lives.
Early backers include Lifeline Ventures and Proxy Ventures, while Iconiq Capital and Fidelity Investments have joined more recent rounds.
In October, it also reported its revenues doubled between 2023 and 2024, and projects it to double again in 2025. It also expected to reach $1bn in sales in 2025, thanks to the surge in demand for wearable technology.
Speaking to Sifted in November 2025, CEO Tom Hale says that Oura’s ability to invest heavily in R&D and its data collection set it apart from rivals.
“We can continue to run ahead on science, new capabilities and new designs. The kind of scale we’ve achieved is, in a way, a moat. There are other competitors, but they cannot invest the way we can.
“What makes Oura so different is the quality, depth, accuracy and frequency of our data. And what is it that makes AI special? It’s the data.”
