In this episode of Retention Chronicles, Mariah sit down with Jo, founder of Nutcase Milk, to unpack how a late-night craving for better-for-you chocolate milk turned into a fast-growing CPG brand with creator partnerships and a hard-earned product reset .

Jo shares how testing the product at her restaurant sparked early demand, how a random Vegas brunch led to VC backing, and how poker connections evolved into partnerships with names like Ninja and Steve Aoki. But the real lesson comes after launch. When repeat purchase didn’t meet expectations, the team made the tough call to pause, reformulate, and improve the product before scaling further.

We talk luck versus determination, founder-led brand voice, handling public criticism, and why retention always starts with product quality. This is an honest look at what it really takes to build in public and get better in real time.
