Who we are:


HyperHeat electrifies industrial heat. We build high temperature electric heating systems that enable steel, cement, chemicals, glass, ceramics, and other energy intensive industries to replace fossil burners with a solution that is competitive, scalable, and reliable in real operations.
Industrial process heat is one of the largest remaining sources of global CO2 emissions. Solving it requires more than good intentions. It requires technology that performs at high temperatures, integrates into existing plants, and wins on economics.
Our products cover a temperature range up to 2000°C and are designed for continuous industrial use. We work with industrial partners on deployments, validate performance under real constraints, and translate that learning into scalable products.
We are building HyperHeat to become the number one supplier of high temperature industrial heating solutions by 2030, deploying more than one gigawatt per year, powered by a proud, talented team.
If you want your work to sit where deep tech meets real world deployment and where analysis directly shapes decisions, you will feel at home here.
