Helical Fusion, a Tokyo-based developer of next-generation clean energy technologies, has closed a $5.5 million Series A Extension round, bringing the company’s cumulative fundraising to $38 million. The new capital expands the company’s investor base through participation from Ecrowd NEXT, a fund tailored for individual investors, as well as multiple corporate and individual backers.
The completion of this extension places Helical Fusion’s total Series A funding, including loans, at approximately $21 million. The company stated that the infusion will accelerate its flagship Helix Program, a long-term roadmap designed to achieve its goal of becoming the world’s first commercially viable fusion power plant.
Helical Fusion is developing clean energy through Japan’s original Helical Stellarator architecture. The company is progressing toward integrated demonstration with its final experimental device, Helix HARUKA. It is targeting steady-state net-electricity fusion power generation with its first power plant, Helix KANATA, during the 2030s.
Founded in 2021, the company focuses on the development of commercial fusion reactors and related technologies. Its cumulative capital comprises equity, grants, and loans. The funding is expected to strengthen its technical development pipeline further as global interest in fusion energy expands.
