Subra develops superconducting cable technology aimed at enabling zero-loss power transmission and supporting fusion energy applications. Following the Series A raise, Subra is acquiring THEVA to combine its cable technology with THEVA's manufacturing expertise and proprietary material science, including high-temperature superconductors and thin-film deposition. The integration is intended to create industrial-scale production capabilities and vertically integrate R&D and manufacturing. The combined company will be headquartered in Denmark while maintaining operations in Germany to scale production and serve international markets. Subra plans to focus on applications across energy systems, infrastructure, research, and industrial markets as it seeks to become a European leader in superconductors.
