Finnish tech company Oura has filed to go public, with its smart ring set to join the ranks of wearable health trackers. Since 2015, Oura has distinguished itself from competitors like Fitbit and Apple by offering a sleek, unobtrusive ring that monitors activity, sleep, and daily readiness.

At the recent Series E funding round, Oura announced it had sold over 5.5 million rings, more than doubling its sales in a single year. This success is set to be bolstered with a new AI model focusing on women's health, catering to their growing customer base.

While SpaceX recently stole the spotlight with its IPO, Oura’s filing shows that even smaller tech companies can make significant waves. As we strive for better wellness through technology, perhaps the ring truly does speak volumes about our health.
