What does it really take to build a cult brand in a trend-driven industry?
In this episode of Where Brands Get Their Edge, Borzou and Amanda sit down with Amir Mostafavi, founder of South Block, to unpack how a local smoothie shop grew into a 21-location brand by obsessing over product, culture, and community.
From pioneering açaí bowls on the East Coast to building a leadership-first company culture, Amir shares the real lessons behind scaling without losing the vibe. They talk about why aesthetics now matter as much as macros, how Gen Z “eats with their eyes,” why data can ruin good marketing, and how purpose needs to be lived, not marketed.
If you’re a founder or marketer trying to grow without becoming generic, this episode is for you.
