The promotion recognises Brenson's nine-year contribution to the agency and reputation he has built for its consumer, retail and shopper division, now an equal and defining part of the business in its 39th year.
A former broadcast journalist at the BBC and ITV, Brenson brings over 20 years of food and drink agency experience to the role. He has built globally recognised and award-winning integrated campaigns across PR, digital, social, influencer and shopper marketing.
His contribution has been a significant part of jellybean winning the World Food Innovation Award for Best Marketing Campaign three times, in 2018, 2025 and most recently 2026. Jellybean says clients describe him as 'someone who understands their business, not just their brief'.
Brenson said: "Food and drink brands are thinking harder and working smarter than ever about how they reach people, whether that’s a chef deciding what goes on the menu, a shopper choosing between products in an aisle, restaurant or forecourt, or a consumer engaging with a brand on social.
“The opportunity for Jellybean is to connect all of those touchpoints in a way very few agencies can. We have the foodservice and trade expertise, the shopper and retail knowledge, the creative, digital and social capability and the best team to bring it all together. I could not be more excited about what that means for our clients."
