For legacy brands, the hardest work isn’t necessarily making change—it’s choosing what to protect. In this episode of Soul & Science, Jason Harris sits down with Stacy Taffet, Chief Growth Officer at The Hershey Company, to talk about what it takes to modernize a over 130-year-old brand portfolio while protecting the meaning people already love.  They also explore how Hershey thinks about snacking moments across candy, salty snacks, and better-for-you options. Plus the role of experimentation when measurement tools don’t capture long-term brand value. And Stacy breaks down a standout example: the Reese’s x Oreo launch, built with a culture-first, fan-powered approach that outperformed traditional playbooks.
