Kayla Itsines net worth tells the most dramatic financial story in modern fitness. She sold an app for $400 million at 29 years old, then bought it back. That single arc contains more about the economics of creator-led brands than most MBA programs will teach in two years.
How Kayla Itsines Net Worth Was Built
Itsines started training clients in her parents’ backyard in Adelaide, Australia. As a Greek-Australian personal trainer who graduated from the Australian Institute of Fitness at 18, her first business insight was about distribution, not fitness. While other trainers handed out business cards, Itsines posted client transformation photos on Instagram. In 2013, she asked “What’s a follower?” at 100 followers. By 2016, she had over 13 million.
The product was deceptively simple: a 12-week high-intensity program called the Bikini Body Guide, sold as downloadable PDFs. Together with co-founder and then-partner Tobi Pearce, they turned that PDF into the Sweat app in 2015. Subsequently, it became the most downloaded fitness app in the world by 2016.
The $400 Million Sale That Defined Kayla Itsines Net Worth
In 2021, Itsines and Pearce sold Sweat to iFIT for a reported A$400 million (approximately US$300 million). The deal structure included $37.5 million in cash, $40 million in Class A common stock, and up to $70 million in deferred consideration. At the time, Sweat was generating roughly $100 million in annual revenue from approximately 450,000 paid subscribers.
However, there’s a complication that most net worth sites overlook. Itsines and Pearce had separated personally in August 2020 while still co-owning the business. Their split didn’t just divide a relationship — it divided one of the most valuable fitness properties on the planet. Both appeared on Australia’s Financial Review Young Rich List with a reported $209 million each in 2020.
The Buyback That Reset Everything
By late 2023, iFIT had pivoted back to fitness hardware. As a result, Itsines and Pearce bought Sweat back for reportedly far less than the original price. In a candid TikTok interview, Itsines admitted: “I think I did it wrong. Sell a company without ‘you’ attached.” She described crying in the gym corner, overwhelmed and unable to separate her identity from the brand.
This buyback is the most underreported story in fitness business. It suggests the $400 million valuation was inflated by iFIT’s pre-IPO ambitions. Moreover, it proves that the true value of a creator-led fitness brand is inseparable from the creator.
Kayla Itsines Net Worth: Revenue Streams Today
The current empire includes the Sweat app (over 13,000 workouts, eight languages, 145 countries), her Instagram presence (16+ million followers, estimated $57,000 per sponsored post), real estate investments including a gas station, and brand partnerships. Additionally, she has two children and is engaged to Jae Woodroffe.
Conservative estimates place Kayla Itsines net worth at approximately $70 million. Higher estimates, which factor in original sale proceeds, push toward $165 million. The truth sits somewhere between, complicated by the buyback terms and the business split with Pearce.
