Grenade Founder Juliet Barratt: Building Carb Killa, Selling To Mondelez & Why Success Felt Like Grief

Juliet Barratt is the co-founder of Grenade, one of the most successful British brands of the last decade.

Grenade started with a single product, a bold idea and a grenade-shaped tub that looked nothing like anything else in the sports nutrition market. At the time, supplements were still largely hidden away in gyms, bodybuilding shops and specialist retailers. Juliet and co-founder Alan Barratt saw a gap: everything looked the same, sounded overly scientific and failed to speak to the mainstream consumer.

So they built something different.

In this episode of Building The Brand, Juliet shares the real story behind Grenade, from launching with limited resources, driving a tank into the NEC to stand out at BodyPower, getting picked up by major retailers, creating the Carb Killa bar, helping bring protein into mainstream retail, taking on private equity and eventually selling to Mondelez.

But this conversation is not just about the commercial success.

Juliet opens up about the emotional reality of building a business that becomes your whole identity. She talks honestly about working with her husband and co-founder Alan, how Grenade became the “glue” in their relationship, why selling the business felt like giving away a child, and why even after financial success, money can still feel like a responsibility rather than freedom.
