Oura Health is prepings its IPO, which will test whether public markets are ready for a new wave of health technology companies.

Oura is the latest household name to test public markets in what is shaping up to be the busiest year for tech IPOs since 2021.

Finnish smart-ring maker Oura has filed confidentially for a US IPO, less than a year after closing an $11bn Series E and crossing $1bn in sales.
