SPACECOOL Raises Total Funding of JPY900 Million in Pre-Series A and Series A Rounds, Expanding Global Reach: Bringing the Coolness of Shade Trees to the World
SPACECOOL INC., developing and providing of the radiative cooling material “SPACECOOL,” which enables zero-energy cooling by emitting heat to space, announced the successful completion of JPY900 million in funding through Pre-Series A and Series A rounds. The funding includes investments from new investors, Mirai Creation Fund III managed by SPARX Asset Management and MITSUI SUMITOMO INSURANCE Venture Capital.

The innovative radiative cooling material, “SPACECOOL,” leverages the principles of radiative cooling to convert heat into infrared radiation and release it into space. This allows for zero-energy cooling even under direct sunlight. By applying the material to outdoor facilities, such as building surfaces and equipment exposed to extreme heat due to global warming, SPACECOOL transforms these surfaces into “Smart Surfaces,” reducing energy consumption for cooling and contributing to the realization of a carbon-neutral society.

In the Pre-Series A round, SPACECOOL raised funding through J-KISS (Japan-Keep It Simple Security) from existing investors, WiL and Osaka Gas, along with new investor Mitsubishi HC Capital Inc. The Series A round followed with additional funding from new investors, Mirai Creation Fund III and MITSUI SUMITOMO INSURANCE Venture Capital, through a third-party allotment of shares. The total funding of the two rounds is ¥900 million.
The funds raised will be allocated toward expanding international sales, advancing research and development, and strengthening organizational and business foundations.
