Oura Health
Oura Health is a Smart Rings & Recovery company founded in 2013 and based in Oulu, Finland. It has raised $1.2B in total funding, most recently an IPO in 2026 at a $16B valuation.
Founded in 2013 in Oulu, Finland by Petteri Lahtela and Markku Koskela, Oura Health designs smart rings that continuously monitor health metrics and deliver daily readiness, sleep, and activity scores through a paired app. The Oura Ring 4, built from titanium with multi-channel sensors, tracks over 50 metrics and syncs wirelessly to the Oura App. Revenue is generated through hardware sales and paid app memberships that unlock advanced trend analysis and algorithm improvements. As of September 2026, Oura has raised $1.2 billion and filed for a NASDAQ IPO valued at $16 billion, though the company subsequently postponed the listing.
Oura operates in the expanding smart ring category and has demonstrated capital absorption through $1.2 billion in funding raised over its history. The company's scale—between 1,000 and 5,000 employees—and planned public market entry reflect material investment in the wearables sector. Recent partnerships like the collaboration with Xella Health signal expansion into integrated health diagnostics beyond standalone ring tracking.
