AlloVoisins is everywhere, but seen nowhere. The platform powers millions of services across France every year, yet remains invisible in the physical spaces where those services are delivered. Most marketplaces communicate through performance channels and product-led messaging. The result: a usage that exists, but a brand that doesn't fully register. The challenge wasn't to explain the service. It was to prove it exists, in the most concrete and unexpected way possible.

A platform doesn't become iconic by talking about itself. It becomes iconic by hijacking codes that people already trust. To grow brand salience, AlloVoisins needed to borrow a symbol so familiar it would be impossible to scroll past, and turn it into proof.

Sleeq imagined and produced "Service Rendu", a campaign built around one of the most recognizable symbols in French streets: the real-estate "VENDU" sign. Hacked into "SERVICE RENDU" signs and installed in Paris, Toulouse, Bordeaux, Lyon and Nantes, each panel featured a real AlloVoisins professional, a five-star rating, and a QR code leading to a contest with up to €500 in vouchers to win. No actors, no fiction: a handyman from Toulouse, a dog trainer from Paris, an electrician from Nantes.
