NOTSHY aimed for significant growth while improving its very assertive brand in a highly competitive universe.


NOTSHY hired Quantads to manage all of its online advertising, with a particular focus on incrementality, branding and seasonality (new product launches, sales, etc.).

With a specific media mix, as well as serious technical constraints, the objective was to multiply turnover while maintaining a target ROAS.

Beyond pure performance, Quantads has actively and deeply worked on the strategic, data, and creative aspects.

actions menées

Quantads first took over the acquisition program during a stress test: an onboarding just before Christmas, a particularly important period for NOTSHY. Once this period was over, the team designed and implemented a comprehensive media plan.

The first building block was a complete overhaul of the data infrastructure to professionalize the identification, tracking, database and visualization of all customer interactions.

With these data, now complete and precise, Quantads orchestrated creative iterations in order to maximize performance while developing the brand itself.

Based on those newly gained insights, the team focused media investments to maximize incrementality.
