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.

 

We believe that sustainability shouldn’t compromise on aesthetics or functionality. This is why our smart and powerful windows remain as transparent and durable as any others.

At PHYSEE we cherish our diverse and inclusive company culture. With currently 8 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.

We are always looking for the next PHYSEEonair to enrich our knowledge, determination, and ability to do so.

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