Creating an ad subway campaign in Paris.
4 million passengers daily. 7 weeks. 250 billboards. 1 message: Sumeria is the first bank in Europe that earns you up to 4% interest.
CONTEXT
Stars aligned
Paris, Olympic Games. The metro had open ad spaces, and for a limited time, massive discounts. We jumped on the opportunity. The catch? We had just one week to create, finalize, and print the campaign—on time for the Games.
Oh, and our brand designer had just left… With no one to take the lead, I stepped up. It was a challenge I wanted to take on, a chance to push myself and prove what I could do.
BRIEF
Campaign objective
One clear message: Sumeria is the first bank in Europe to offer 4% interest on your total balance. A bold statement designed to drive acquisition.
I explored multiple directions, iterated fast, and refined the concept. The final campaign was shaped alongside our VP Design, Félix Lepoutre, and the leadership team. Below, you’ll find the creative process that led to the final result.

In just one week, we turned an ambitious idea into a city-wide campaign seen by millions. A bold statement, a real impact.
