Born from frustration
GuusLab began because sharing beautiful work often felt clumsy. The tools we used every day didn’t feel like they were made for designers who care about presentation as much as performance.
An experimental design studio crafting tomorrow’s digital experiences.
GuusLab is led by Guus Kaashoek. We blend design, storytelling, and engineering to produce software that feels like a brand film. ZIP is the first platform to receive our full glow.
Building the future of sharing
ZIP is our response: a single platform that feels like a private gallery, developer handoff, and production vault rolled into one.
Design for humans
Every interaction—from the color of the share link button to the rhythm of notifications—is tuned to feel personal, intentional, and calm.
Guus Kaashoek
Founder & Lead Designer
“I believe the products we rely on should feel like art direction. ZIP is where we prove it.”
Design first
We prototype relentlessly. If the pixel language doesn’t feel fresh, we keep iterating until it does.
Experimental mindset
Every product is a laboratory. ZIP is the flagship, but GuusLab explores new interfaces weekly.
Crafted for teams
From freelancers to full studios, we obsess over the tiny details that make collaboration addictive.
Studio philosophy
We’re a playground for bold ideas, fast iterations, and emotional interfaces.
Whether we’re crafting ZIP or prototyping the next experiment, everything starts with a story. We design the mood first, then engineer something that feels like magic.
