Oura's business model relies on selling the hardware, as well as on a $5.99 monthly subscription service that allows users to get the insights from their ring. Oura says it has nearly 2 million subscribers.
"We look more like a software company than we do look like a hardware company. And I think that's a function of the business model, and the fact that it's working. Our subscribers are continuing to pay," Hale said.
