Oura Ring 5 is 40% smaller than prior versions and includes detection capabilities for hypertension and sleep apnea according to Bloomberg and New York Post reporting. Multiple financial and operational claims about Oura, including an $11 billion valuation, $1 billion revenue, 5.5 million units sold, and a confidential IPO filing, originate solely from unverified New York Post reporting. Partnerships with Essence Health and Counsel Health are also cited only in that source.
