Danish deep-tech startup Subra has closed a €40 million Series A round led by Novo Holdings, with participation from the Export and Investment Fund of Denmark and Germany’s SPRIND. The funding coincides with Subra’s acquisition of THEVA Dünnschichttechnik, a Munich-based superconducting materials manufacturer founded in 1996.

Subra develops high-temperature superconductor cable technology designed to reduce energy losses in electricity transmission. Its acquisition of THEVA combines Subra’s cable expertise with THEVA’s established manufacturing capabilities, aiming to scale production and accelerate product development for energy, industrial, and research applications.

The combined company will operate from Denmark while maintaining THEVA’s German facilities, reinforcing Europe-based manufacturing in a strategically critical technology sector.

The Series A proceeds will support the integration of the two businesses, expand production capacity, and advance the development of high-performance superconductors for European energy infrastructure
