Our story

Design by Theory was created by David Cliff. After two decades designing for iconic Yorkshire brands, and setting up a few of his own, Design by Theory was founded on his experience that effective design is born from strong, theoretical foundations. Relentlessly curious, David works with businesses to uncover what makes them unique, translating this into compelling design that connects them with their customers.
