Kayla Itsines sold her fitness platform Sweat for a reported £316 million ($400 million) in 2021. Four years on, she owns every share of the company again.
The Adelaide-born entrepreneur, 35, became Sweat's sole proprietor in March 2026. It was the final step in a process that began in late 2023, when Itsines and co-founder Tobi Pearce first bought the app back from US fitness equipment company iFIT Health & Fitness for an undisclosed sum. She has since acquired Pearce's remaining stake.
