Epyr

Pre Seed · Climate Tech · Paris, France · Founded 2024 · 11–50 employees

Paris-based climate technology startup Epyr specializes in decarbonizing industrial heat through industrial-scale Thermal Energy Storage systems. The company's technology converts low-carbon or renewable electricity into thermal energy during surplus generation windows, storing it in high-performance ceramic firebricks to release on demand as steam. Epyr operates on a heat-as-a-service model, eliminating upfront capital expenditure for industrial facilities in sectors such as paper, chemicals, and food processing. In February 2025, the firm secured a three million euro pre-seed funding round to advance its commercial deployment. Additionally, the company has secured a subsidy from the French State, operated by ADEME under the France 2030 initiative, to support its industrial pilot projects.
