What if the apps posting the best revenue screenshots are the ones nobody actually uses? In this episode of Growth by Design, we sit down with Seth Miller, founder and CEO of Rapchat, who spent 13 years building a consumer music app to 15M+ users and 100M+ raps recorded — then rebuilt the whole operation around AI agents. Drawing on a decade of consumer app building, a Series A, and the decision to get off the VC treadmill, Seth unpacks how to tell when your product has hit its ceiling, why UA-dependent businesses are more fragile than they look, and what changes when agents ship you TestFlights every day.
In this episode of Growth by Design, we sit down with growth product manager Luke Longworth — an early Superwall adopter who's spent years optimizing paywalls and subscription funnels for apps big and small.

Hanna Grevelius (CPO at Bruce Studios) on why simpler — even "ugly" — paywalls often outperform polished ones, and how teams get misled by metrics.
