About Us

At PHYSEE, we believe in people. Without a determined and enthusiastic team of PHYSEEonairs, our mission would just be a dream. Together, we are unleashing the full potential of clean building facades.

Our Vision

We envision a future of energy neutral buildings where user’s comfort and productivity levels are increased. Therefore, we are balancing out the energy demand by producing and consuming electricity locally, providing tomorrow’s buildings with the SmartSkin they deserve.

At PHYSEE, we cherish our diverse and inclusive company culture. With currently 10 different nationalities onboard, we value every added perspective as we feel it is our responsibility to change the world’s perspective of a sustainable future.

If you are as inspired as we are on changing tomorrow’s buildings, join us on our mission. We are stronger together!
