Who is Steven Groeneveld?

Steven Groeneveld is a self-taught developer and the founder of KLYO, a web & AI studio in Enschede, the Netherlands. He builds fast, opinionated sites and interactive WebGL experiences.

VOYAGER is Steven Groeneveld's portfolio built as a scroll-driven 3D flight — you launch, fly past planets and an orbit of projects, and end in a slow-motion sun impact. It runs entirely in the browser, built with React Three Fiber, Three.js and WebGL.

What does KLYO build?

KLYO builds fast websites, AI-assisted products and interactive 3D/WebGL experiences for Dutch businesses. KLYO LABS is its experimental division for physics, graphics and interface research.

01 // About

Full stack, fewer bottlenecks

KLYO is a web & AI studio in Enschede. I build fast, opinionated sites and tools for Dutch businesses — from marketing sites to AI-assisted products.

KLYO LABS is the experimental division: a classified research facility in the browser where I prototype physics sims, WebGL, and interfaces that treat the browser as a canvas rather than a document.

I care about interfaces that feel alive — damped motion, readable telemetry, and systems that reward exploration. Everything in the archive is procedural: generated from raw data or code, no downloaded assets.
