Designers, engineers, and AI agents powered by curiosity and craft.

The 35 studio in Maastricht

About us

A studio that takes ideas from zero to one, and much further. We punch well above our weight, because half our studio doesn't sleep. We think in systems instead of deliverables. Some days that means refining the tiniest interaction for hours. Other days it means shipping an entirely new direction before lunch.

Our studio was built around a simple idea: great products happen when the people making them stay close to the work. Just a tight group of designers, engineers, and problem-solvers obsessed with building things that feel clear, useful, and inevitable.

We've embedded agents deeply into the way we work. Research runs while we sleep. Ideas get stress-tested instantly. Workflows evolve in real time. It gives us the speed of a much larger studio, without losing the sharpness, taste, and intuition that only humans bring.
