BOSH!’s Challenger Brand Playbook: Founders Henry Firth & Ian Theasby

This week, I’m joined by Henry Firth & Ian Theasby, the founders of BOSH!, to explore how an audience-first approach helped them build one of the most recognisable plant-based consumer brands in the UK. For founders scaling challenger brands, this is an incredible lesson in brand growth through content & community first. Long before their recent Tesco launch with their delish PIZZA, BOSH! had already spent years building attention, trust and demand through daily recipe content, bestselling cookbooks and a clear mission to put more plants on plates.

What makes this conversation especially useful is that Henry and Ian did not stumble into this model by accident. They set out to build a food brand, but chose to do it the lean way: validating demand, learning from audience behaviour and evolving from videos to cookbooks, licensing and then fully controlled product ranges. We talk about how they used views, comments, polls and first-principles thinking to shape products, why they moved away from licensing, what it took to launch into Tesco in just nine months, and what all of this means for founders who want to think more like media companies and less like traditional CPG brands.
