The Series C round of funding, led by The Chernin Group and Elysian Park (the investment arm of the Los Angeles Dodgers), brings the wearable tech company’s total funding to $148.3 million. To date, Oura has sold more than 500,000 of its wedding-band sized rings that track wearers’ activity — including sleep, steps, heart rate, and body temperature. This year, researchers from the University of California San Francisco have tried to predict Covid-19 infections in health care workers by using the Silicon Valley-favourite device.

The ring comes in different metals and price points ranging from a $299 silver piece to a $999 diamond studded one.
