Case Study: Carrefour achieves higher ROAS and saved hours with Hunch

How So Buzzy automated Carrefour’s end of year campaigns using Hunch

Carrefour worked with Hunch through social media agency So Buzzy to automate its end-of-year paid social campaigns in Belgium. With hundreds of stores and thousands of products, Carrefour needed a way to run highly localized holiday ads at scale, promoting the right store and product to people within a specific radius while avoiding creative fatigue.

Using Hunch’s Creative Studio, Multi-artboard, Feed Mapper, and Automated Campaign tools, So Buzzy generated 100+ creatives, built hyper-localized product and store-map ads, and automated countdown campaigns. The result was 250+ hours saved in manual work, a 28% higher purchase rate, 31% higher ROAS, 4.1x higher CTR for recipe ads, and significantly better localization performance, including 81% lower CPM than the target.
