80 - Craving Change w/South Block CEO Amir Mostafavi
Welcome to Digital Doorways . I'm your host Jason Siegel, founder and managing partner of Bluetext , and this is the show where we sit down with the CEOs, CMOs, and creative leaders who are actually doing the work — building brands, navigating change, and figuring out what it means to lead in a market that does not slow down for anyone. My guest today is Amir Mostafavi , founder of South Block , the juice and açaí concept he launched in Clarendon in 2011 and has since grown to dozens of locations across Virginia, D.C., and North Carolina. What makes his story worth an hour of your time is not just the growth — it is how he built a brand with a real point of view. Live in the Present is not a tagline at South Block. It is the operating philosophy. And figuring out how to keep that authentic while scaling is exactly the kind of problem this show exists to dig into. Amir, welcome to Digital Doorways. QUESTIONS FOR AMIR Origin & the leap You grew up in McLean and trained as a graphic designer — not exactly the obvious path to running a juice and açaí empire. Take me back: what was the moment you knew you were going to leave design behind and bet on this? You've said you fell in love with the California-style juice bar. What specifically did you see out there that told you "this doesn't exist at home, and it should"? Before South Block, there was Campus Fresh at GW in 2006. What did that first venture teach you — and what did you carry forward, or deliberately leave behind, when you launched South Block in 2011? Brand, design & positioning You come from a design background, so I have to ask — how much of South Block's success do you attribute to the brand and the visual experience versus the product itself? Where do those two things meet? When you were building the South Block identity — the name, the look, the feel — what were you trying to make people feel the moment they walked in? "Live in the Present" is more than a tagline for you. How did that philosophy come about, and how do you keep a brand promise like that authentic as you scale to dozens of locations? The health food and juice space has gotten crowded and competitive since 2011. How do you think about differentiation today — what makes a customer choose South Block over the shop across the street? Growth & navigating change You went from one block in Clarendon to a regional chain across Virginia, D.C., and North Carolina. What was the hardest part of making that leap from a single beloved location to a multi-unit brand? Every founder hits a moment where the thing that made you special at one location starts to strain as you grow. When did you feel that tension, and how did you protect the culture? Expanding into North Carolina meant entering a market that didn't already know you. How did you approach building the brand in a place where you had no home-field advantage? Food and hospitality got completely upended by the pandemic. Walk me through how you navigated that stretch — what you changed, what you refused to change, and what you learned about the business. So much of consumer buying moved to mobile, delivery, and app-based ordering. As a physical, community-rooted brand, how have you thought about the digital side without losing the in-person magic? Community & people Behind every location is a team. As you've grown, how have you thought about hiring, training, and keeping the people who represent your brand to customers every single day? What's a piece of feedback from a customer or an employee that genuinely changed how you run the business? The future Where do you want the South Block brand to be in five years — and is that a story about more locations, new products, new markets, or something else entirely? For the entrepreneur listening right now who has a great idea and a day job they're afraid to leave — what's the one thing you'd tell them about walking through that door?
