Our Story

Founded in May 2023, GIGAette emerged from cutting-edge research in thermal dynamics and energy storage at KAIST (Korea Advanced Institute of Science and Technology). Our founders recognized that industrial waste heat represented one of the largest untapped energy resources globally.

Through years of research and development, we developed the revolutionary IsoTES® (Iso Thermal Energy Storage) technology, featuring the unique thermal piston effect that enables single-tank, constant-temperature output.
