Gallium Oxide startup NextGO Epi raises €2m
NextGO Epi, a Berlin-based startup developing Ga₂O₃ epitaxial wafers for next-generation power semiconductor devices, has secured a €2 million pre-seed funding round.
The round, its first institutional backing, was led by Vireo Ventures, with participation from Ultratech Capital Partners, IBB Ventures, and angel investor Boris Habets.
Founded in 2025 by Ta-Shun Chou, Andreas Popp, and Andreas Fiedler, the company is a spin-off from the Leibniz-Institut für Kristallzüchtung (IKZ) and claims to be the only European company producing Ga₂O₃ epitaxial wafers at industrial quality up to 4 inches.
Ga₂O₃ offers a significant efficiency boost compared to the widely used SiC. The German startup notes that it is 10x more power-efficient, handles up to 6x higher voltage density, and can be produced for up to 75 percent less cost.
The company is already in production, generating revenue, and serving customers across three continents.
The most immediate application is EV fast charging. NextGO Epi says its product can fully charge a vehicle in just 10 minutes, compared to the usual 60 minutes, according to the company.
NextGO Epi plans to use this fresh capital to accelerate product development, grow the team, and strengthen the company’s commercial presence across Europe and beyond.
