International push
Hale's presence at the Web Summit in Lisbon underscores his push to raise Oura's brand awareness in markets outside of the U.S., especially as more people learn about smart rings.

"I think the point about the category being something that people are learning about, the unique benefits of that maturity, is in our favor. We're expanding internationally," Hale said.

He said he is particularly "excited" about venturing into Western Europe, including in countries like the U.K., Germany, France and Italy. Looking even further forward, Hale said an initial public offering for the business is not currently on the table, adding that operating as a private company gives Oura more "freedom."
