Company
From what is thrown away,we make what is needed
Thermophene is a thermal materials company cooling AI hardware and EVs. Our carbon comes from coffee grounds that cafés throw away.
01Mission & Vision
Mission and vision
Beyond Cooling, Towards Green.
We go beyond cooling and change how materials are made.
-
Efficiency
Nothing wasted
We use 100% of spent coffee grounds. Carbon costs almost nothing and by-products earn revenue first.
-
Performance
Proven by performance
Led by a 12 W/mK isotropic thermal material, we also make deodorizer and cosmetic ingredients.
-
Value
Carbon-neutral supply chain
We fully valorize biomass and localize thermal materials that depend heavily on imports.

03Problem
Why westarted this
Heat is rising, rules are tightening and materials depend on imports. We want to solve all three with one material.
-
01
Performance bottleneck
A single GPU now draws over 1,000 W. Conventional materials cannot remove that heat, cutting performance and lifespan.
-
02
Safety and reliability
After 30+ ESS fires in Korea, safety rules rose. Always-on data centers and EVs need materials that last.
-
03
Supply chain and ESG
80% of premium fillers are imported from Japan, the US and Germany. With EU CBAM from 2026, low-carbon materials are a must.
