The company reported it is on track to exceed five million paid members this quarter, representing a fourfold increase over two years. Total revenue has grown fourfold over the same period. Oura was valued at $11 billion following its October Series E funding round of $900 million. The company has been named to the CNBC Disruptor 50 list four times, most recently ranking No. 14 in 2026.
