PHYSEE Technologies


We are a technology company from Delft, engineering smart solutions for the global energy transition. Our solutions aim to activate existing materials, for undiscovered, sustainable impact. Our mission started with activating a single window with solar functionality, however, our curiosity has continued into engineering new solutions for crop growth inside greenhouses, as well as efficient equipment that produces customizable solar for endless applications. Across all these solutions, we consistently aim to change the perspective on how current materials are used and implemented, as well as challenging the system innovation behind them. The future we envision is one with energy-neutral buildings, centred around human comfort, and filled with sustainable solutions that don't compromise on aesthetics or functionality. Our growing team of 40 PHYSEEonairs work on Research & Development, Production and Projects to ensure the future we envision.
