2025 Stage Two Semifinalist

This October, the Ætheria team traveled to Berlin to participate in the Stage Two 2025 Finals—Europe’s largest startup competition for university-based ventures. Hosted at RWTH Aachen and TUM, Stage Two brings together the top early-stage founders from leading universities across Europe, offering a platform to pitch, learn, and build the partnerships that drive real-world innovation.

Selected from hundreds of applications across more than 40 universities, Ætheria was proud to represent Maastricht University and the Brightlands Chemelot Campus on the finals stage. In Berlin, our team presented our mission to address one of the most overlooked climate challenges today: the potent greenhouse gases trapped in end-of-life insulation foams.
