Tobi Pearce and co-founder Kayla Itsines grew Sweat, now a globally recognised fitness brand and one of Apple’s most downloaded health apps, from what was, in 2015, an e-book called the ‘Bikini Body Guide’' (or 'BBG', for those in the know).  Tobi joins us in a bonus episode of Unconventional Business, live from GROW, to talk about the brand’s explosive growth over the last seven years and how he and Kayla took the brand from e-book to app, and where they drew inspiration from.  Kat and Tobi dig into the critical role of customers in subscription business models, how Tobi thinks about driving value for customers, how the Sweat team harnesses the feedback and insights from their global community of more than 50M, where Tobi goes for innovation and what’s coming next for the homegrown success story.
