We Grow Purpose-Led Brands.

Combining human-first creativity and performance expertise to drive commercial results, conscious consumption and positive behavioural change.

Independent, boutique & highly specialised.

We care deeply about the brands we work with, especially because of the impact they want to make on the world. We strive to be endlessly curious and relentlessly determined in our pursuit of great ideas and performance. We work with people that love their craft, to deliver brand growth with exceptional human-first creative. We are a founder-led agency that’s full of passion for what you do and the performance of your business.

Our Core Pillars.

We’re an independent, boutique agency in the North.

“Salt Mule completely understood our mission to drive real, sustainable change across the UK. They delivered a strategy aimed at increasing local sign-ups for People, Planet, Pint, with the goal of scaling across our national meet ups. Their toolkit offers insightful concepts and messaging and new ways for us to reach our local audience via organic and paid channels, all while considering practical and commercial constraints. We look forward to continuing our partnership with them.”
