"Working with Mustard was great, they assisted with product insight into some of our paper map titles. From start to finish they made the whole process seamless, weekly calls to keep us updated until the insight was physically carried out and then a fantastic debriefing session at the end of all the work! Keep up the good work!”

"Mustard consulted with HCPs to inform the launch of our new breast-feeding innovation, Munchkin Flow Nipple Shield +. They totally grasped what we wanted to achieve and were super easy to work with. The insight gleaned has been crucial in shaping our proposition & strategy – Mustard’s recommendations drove decisions around the product, price, and marketing. We’re excited to see the impact of the full campaign, which includes advertising on the London Tube, ITV spots, an Emma`s Diary campaign and influencers! I would 100% recommend working with Mustard to refine any new proposition and strategy."

"Mustard were genuinely nice people to work with - nothing felt like it was too much trouble. They’re very transparent, and offered some new, innovative approaches that delivered richer insights, and had good reasoning for changes proposed. The findings were rich, and the AI prompts delivered some great additional insights. A great experience! We are using the data to inform our ongoing business planning – ensuring we’re focused on the areas that we now know matter most to our members."

Head of Brand Relations

SimpliSafe UK

"Mustard have become far more than a research agency to us. They’ve been a sounding board, a strategic ally, and — more than anything — an extension of our team. Not just listening, but challenging, asking smart questions, brainstorming things through. That kind of collaborative thinking is rare. It’s not a client-supplier dynamic. It’s proper partnership. They’ve worked directly with our MD and senior leadership team, delivering insight that’s landed right at the top."
