OUR TEAM

We are a team of engineers, scientists, and designers with a foundation in practiced design. We combine semiconductor research with elegant hardware to solve personal thermal challenges through data-driven innovation.

OUR MISSION

Redefining the Way 
We QOOL

Sidney Tang is an inventor and entrepreneur with a foundation in trained and practiced architecture. His shift toward high-tech innovation was signaled by early recognition from NASA for a space station design competition, eventually leading him to transition from large-scale projects to micro-scale hardware. This journey resulted in the patented TTFIC semiconductor platform and the award-winning QOOLMATE.

 

Sidney’s work in thermal modulation has earned an iF Design Award, a Gold Medal at the Geneva Inventions Convention, and patents across the U.S., China, Japan, and South Korea. Currently part of the HKSTP incubation program, he remains a dedicated advocate for design thinking and STEAM education.
