The client and the challenge
Yam Nutrition is a French sports nutrition brand founded by Christophe Bonnefont and Don Pierre Albertini. Proteins, supplements, a genuine standard of quality. And a problem every brand in the sector knows: sports nutrition is probably the most saturated market in French e-commerce. Dozens of brands, the same promises, the same shaker-and-gym visuals, and advertising costs rising every year. In that context, spending more is not enough. The question was not “how do we run more ads”, but “how do we make every advertising euro actually pay”.
What we understood
The usual reflex in this situation: change audiences, change agency, raise the budget. Our diagnosis was elsewhere. Traffic was not the only problem: part of the visitors landed on pages that did not convert enough. Driving people to a shop whose window does not make them want to come in means paying twice. So we refused to treat advertising as an isolated topic. The setup had to work both ends of the chain at once: creatives that stop the scroll, and sales pages that close.
What we did
For twelve months, the team worked in a continuous cycle: designing creative angles, producing content, running it on Meta, reading results, iterating. Every creative is built for a precise goal, never to fill a calendar. In parallel, deep work on the sales pages: structure, argumentation, proof, a smooth path to payment. That is the invisible lever of winning accounts: when the site's conversion rate rises, ALL campaigns become more profitable at the same time. This only works because everything happens in one place: strategy, creative and measurement do not pass the ball between three vendors, they share the same office in Nice.
“Working with Brainlab has been an extremely positive experience. The team is highly effective at content creation and sales page optimisation, which significantly improved our conversion rates. A partner of choice.”
