ŌURA
Oura makes the Oura Ring, a smart ring for sleep, activity, readiness, stress, heart health, metabolic health and women's health. It sells to consumers directly and through retailers such as Best Buy and Target, and to enterprise customers including the U.S. Department of Defense. Most revenue comes from the ring itself: hardware was $974.0M of $1,214.5M in the nine months to 30 June 2026, about 80%. The rest comes from an optional paid membership at $5.99 a month or $69.99 a year in the US. The company was founded in Oulu, Finland, moved its parent company from Finland to Delaware in March 2026, filed an S-1, and postponed its Nasdaq IPO on 29 September 2026.

- Oura Membership · $5.99/mo · $69.99/yr · optional ↗US price is $5.99 a month or $69.99 a year. Elsewhere: €5.99 / €69.99 in the EU, CA$7.99 / CA$89.99 in Canada, A$9.99 / A$109.99 in Australia. New members get the first month free, and the membership is HSA/FSA eligible. It adds Oura Advisor (the AI health companion) and every new feature. Without it, the ring and app still work, but insights are 'much more limited'. Membership was about 20% of revenue in the nine months to June 2026, with an 89% membership gross margin, and about 63% of new members chose annual plans (S-1/A).
