I make mascots brands can own.
Stef Hamerlinck. Brand designer and strategist from Belgium, working with brands worldwide.
After 20 years as brand strategist and designer for global brands and agencies, I now focus on one thing: mascots. The kind a brand can own for decades, not a campaign.
Every mascot starts on paper and is grounded in the research on distinctive brand assets. Then I build a world around it and a custom AI engine, so the team can put it anywhere and it always looks like itself.
I work on the edge of new technology, exploring where craftsmanship meets generative AI, and share what I learn on stages and podcasts like Tectonic, Logo Geek and Brand Builder Summit. And in Marcel's Lab, my newsletter for 4,000+ readers. My own mascot is Marcel, a big blue dog in an orange cap.
