Oura said Tuesday that it raised over $900 million in a new Series E funding round, bringing the company's valuation to $11 billion.
The fundraise, led by Fidelity Management & Research Company, also includes new investor ICONIQ and contributions from Whale Rock and Atreides.
"With this investment, we will accelerate innovation, expand our global reach, and set a new standard for what wearables can achieve in advancing preventive health," said CEO Tom Hale in a statement.
The Finnish company, which ranked No. 23 on CNBC'S 2025 Disruptor 50 List, has raised approximately $1.5 billion, according to a release.
Known for its Oura Rings, the company competes with other smart ring makers like Samsung and RingConn, as well as fitness-focused devices from Whoop and Garmin.
Oura announced in September that it has sold over 5.5 million Oura Rings since the product's launch in 2015, a significant jump from 2.5 million rings announced in June 2024. The company reported revenue of over $500 million in 2024, more than double from the year prior, and expects to reach $1 billion in sales this year.
