ŌURA, maker of the most trusted smart ring, Oura Ring, has raised over $900 million in Series E funding led by Fidelity Management & Research Company with participation from ICONIQ and contributions from Whale Rock and Atreides. ŌURA will use the funding to boost AI, innovation, global reach, and health features.

ŌURA was founded in 2013, and has offices in Oulu, Helsinki, San Francisco, and San Diego. ŌURA’s main product, ŌURA Ring, a smart ring for personalized health data, offers insights and daily guidance, promoting healthy habits and connecting individual well-being with collective outcomes. 

The ŌURA Ring’s sensors collect data on more than 20 biometrics like heart rate, heart rate variability, blood oxygen levels, body temperature, menstrual cycles, and movement to track metrics like sleep patterns and activity levels.  According to the company, the product now has more than 1 million members.

“This new funding is a testament to the strength of ŌURA’s business and the trust millions of members place in us every day. We’re proud to be building not just a product, but a global movement toward proactive health—helping people understand their bodies, make better lifestyle decisions, and connect more effectively with their healthcare providers. 

Today, our technology supports consumers, employers, insurers, and clinicians working together to advance preventive health at scale. 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 Tom Hale, chief executive officer at ŌURA.

The round was led by Fidelity Management & Research Company with participation from ICONIQ and contributions from Whale Rock and Atreides. Fidelity Management & Research Company (FMR Co) is the investment management arm of Fidelity Investments, one of the largest financial services firms in the world. 

FMRCo manages assets for institutional clients, including pension funds, endowments, and other large entities, as well as for individual investors through various mutual funds and ETFs.

As part of the company’s continued growth, ŌURA announced David Shuman, founder of Lateralus Holdings and Oura board member since 2016, as its new Chair of the Board, succeeding Eurie Kim, who has served in the role since 2019.

The investment valuing ŌURA at approximately $11 billion. ŌURA plans to use the new funding to accelerate AI and product innovation, expand global distribution, and invest in development of new health features, cementing its position as the leading platform for proactive health.
