Oura Raises $875 Million and Grows to Almost $11 Billion — Ukrainian Fund Among Investors

Finnish smart ring maker doubles valuation in Series E round, with Ukrainian fund Roosh Ventures among early supporters

Oura Health Secures Record Funding

Finnish company Oura Health, the producer of the globally popular Oura Ring, has raised $875 million in a new Series E financing round, boosting its valuation to $10.9 billion. According to Bloomberg, the round could still expand to over $900 million as negotiations with investors continue.

In parallel, Oura secured a $250 million credit line from leading global banks, strengthening its financial position for rapid expansion.


Sales Growth and Market Outlook

Oura’s rise is one of the most significant in the wearables sector:

  • 5.5 million+ rings sold to date, including 3 million in 2024 alone.

  • $500 million revenue in 2024, with $1 billion expected in 2025.

  • 2026 forecast: sales projected to exceed $1.5 billion.

This trajectory places Oura among the fastest-growing health-tech companies globally.


Ukrainian Participation: Roosh Ventures

Ukraine’s Roosh Ventures was one of the investors in Oura’s earlier financing round in 2021, when the company raised $100 million. At that time, the company’s valuation was estimated by Bloomberg at around $800 million.

Roosh’s early involvement illustrates how Ukrainian venture funds are increasingly active in the global technology and health innovation sectors.


Total Investment History

  • 2020: $28 million raised.

  • 2021 (Series D): $100 million raised (Roosh Ventures participated).

  • 2025 (Series E): $875 million raised, valuation grows to $10.9 billion.

  • Total capital raised: over $1.2 billion.


Why It Matters

Oura is not just a consumer electronics company — it is shaping the future of digital health monitoring. Its rings track sleep, recovery, readiness, and fitness metrics, competing with Apple Watch, WHOOP, and Garmin devices.

With this financing, Oura plans to:

  • Expand R&D and improve biometric accuracy.

  • Grow international sales and partnerships.

  • Explore integration with healthcare systems worldwide.
