A differentiated brand entering a crowded category

A fast-growing international brand, known for its lower-calorie, higher-protein proposition, expanded into the UK to tap into rising demand for healthier indulgence. While it had strong momentum abroad, it needed to establish awareness and relevance with UK shoppers.


A shared ambition to grow both brand and category

Working closely with Tesco and dunnhumby media, we set out to deliver a data-led, multichannel launch. The focus was clear: drive awareness and sales for the brand while generating incremental growth for the wider ice cream category.


Insight-led targeting to reach high-value audiences

Using dunnhumby’s customer insight and media capabilities, we identified and activated priority audiences – including shoppers new to or lapsed from the category. Close alignment on objectives ensured the campaign was both targeted and measurable.


A campaign that delivered rapid impact

The data-driven approach enabled the brand to scale quickly while contributing to category growth:
