At the age of 14, Kustomtype's founder Coert De Decker began his journey into the world of type and design communication by creating hand-drawn posters and flyers for various events including parties and other events, especially for the exciting rock or alternative music scene. This opportunity allowed Coert a venue to develop his own sense of style and creative aesthetic.

Years later, in 1983, Coert started his professional graphic design career as type cutter & stone carver assistant, which was manual business at that time.

In 2011, Coert De Decker founded Kustomtype. Kustomtype is a bustling small type foundry based in Belgium.
