10 Luxembourg Startups
To Watch
The most exciting startups aren’t always the loudest ones in the room. We’ve done the scanning. Here are the ones you need to know.
At ClearSpace, we are committed to building a more resilient, secure and sustainable space ecosystem. We support international efforts to shape the policies, standards, and regulatory frameworks needed for responsible and commercially viable space operations. We are a leading In-Orbit Servicing (IOS) company with a vision to enable a circular space economy by bringing maintenance and services to orbit.
We are CRAB — Circular Resource Analysis Bridge — and we exist to bring clarity to the unseen. Our mission is to open the black box of what happens to materials, products, and packaging at the end of their life, through easy-to-deploy, cost-effective, and automatic AI-driven analysis of resource streams. By making the invisible visible, we empower circularity not just as a concept, but as a measurable, actionable process.
