Advi Bishnoi, Head of Consulting at Social Plus, argues that in 2025, retention has overtaken acquisition as the real growth engine for apps. From Ulta Beauty to Harley Davidson, Advi has helped brands turn community features into measurable revenue streams. In this episode, he explains why micro-communities and in-app social layers transform loyalty programs, how first-party data becomes indispensable in a privacy-first world, and why marketers need to stop fixating on CPMs and CAC. The conversation maps out how fitness apps, travel platforms, sports teams, and retailers all harness community differently and why organic engagement often beats promotions or retargeting in driving long-term retention.
