PERSONAL NOTE.
Looking back at the time when I first set foot in stadiums, it wasn’t just the game that captivated me. It was also the partners that caught my eye. I discovered my deep passion for sports business, and soon after, for experiential marketing. This led to a series of valuable (work) experiences. I have seen how sports can make a difference for people and brands. No matter the goal.
Today, I’m here to help you. United by Sports is a creative production agency in sports. We focus on live experiences and community building, and we see production as an invaluable asset behind every strong creative idea. It’s how the activation with the Eredivisie has sparked a wave of self-belief in Morocco’s next generation.
Ideas alone don’t move the needle. Execution does.
– Kay de Leeuw
