Smart ring makers file Oura for public viewing

Images of SpaceX may have stolen the show with its IPO hopes, but Elon Musk’s aerospace-AI-data center company wasn’t the only notable business to go public this week. On Thursday, the Finnish smart ring company Oura he said that it privately filed a Form S-1 with the US Securities and Exchange Commission in preparation for the IPO.

Launched in 2015, Oura has emerged as one of the most prominent wearable health wearables, setting itself apart from Fitbit, Garmin, and Apple watches with a sleek, unobtrusive ring.

The Oura ring tracks activity, sleep, and daily “readiness” among other health metrics, and today has customers around the world. During its Series E last September, Oura said it had sold 5.5 million rings to date, a big jump from the 2.5 million it reported last year.

That Series E saw Oura rise $875 million at a price of $ 11 billion, more than double the price of $ 5 billion that it previously acquired in 2024.

The company recently introduced an AI model for planning women’s health in order to fulfill its growing base women customers.
