Oura is an award-winning wellness ring and app, designed to help you get more restful sleep and perform better.

Oura helps you find your perfect balance - and stay in the zone.

Oura was founded in 2013 and is headquartered in Oulu, Northern Ostrobothnia, Finland, with offices in Helsinki, Finland and San Francisco, California.


Oura tracks your sleep habits to help you achieve better sleep. It does this by measuring the blood volume pulse from your finger’s palmar arteries, detecting the direction and intensity of your body’s movements using a 3D accelerometer and gyroscope and by measuring your temperature through three NTC temperature sensors.


Oura is backed by Gradient Ventures, Square, Forerunner Ventures, MSD Capital, YouTube co-founder Steve Chen, Twitch co-founder Kevin Lin, Sunrise founder Dave Morin, JUMP founder Ryan Rzepecki and others. The company raised $28M in a Series B round on Mar 17, 2020. This brings Oura's total funding to $48.3M to date.
