NEW YORK, USA // Sébastien Vandecasteele is the Founder and Chief Operating Officer of SLAPS, an independent creative studio with offices in New York, London, and Barcelona. He founded the company at 26 from a small studio apartment in Barcelona, without prior agency experience, industry connections, or outside investment. In just six years, SLAPS has grown into a globally recognized creative force in pop culture, delivering campaigns for brands including Nike, Under Armour, Oakley, Puma, Perplexity, and other leading names across sport, lifestyle, and entertainment.

At the core of SLAPS is a simple but distinct philosophy: live culture rather than comment on it. The studio focuses on building belonging instead of just selling products, and creating obsession rather than content. In a landscape where many brands still talk at younger audiences, SLAPS is known for speaking their language—crafting work that resonates within culture.
