Episode 4: How Two Determined Brothers Built a Beloved Gluten-Free Brand

In this episode of Gluten Free Unwrapped, Jenny Finke speaks with Marshall Rader, the co-founder of The GFB.

When Marshall and his brother, Elliott, embarked on the gluten-free diet over a decade ago, they quickly realized how few nutritious and tasty gluten-free options existed, especially in the protein bar space. Thatโ€™s when they decided to take matters into their own hands and create The GFB.

This family-owned company produces a range of plant-based, gluten-free, and protein-rich bars, bites, and oatmeal cups at its certified gluten-free, zero-waste facility. Marshall and Elliot are committed to using ingredients that are wholesome, understandable, and good for you.

In this episode, Marshall shares:

  • The origin story of The GFB.
  • How he and his brother developed recipes that tasted good without having any culinary training.
  • Some of the early challenges of starting a gluten-free brand and the importance of getting the right in-store placements.
  • What itโ€™s like working with family.
  • How The GFB expanded its offerings, and how that changed the business.
  • Why being a Certified B Corp status is important to the brothers.
