About Tensor Energy

Tensor Energy Inc. is a Japanese technology startup founded in 2021 by Nana Hori and Vincent Filter, developing an operating system for the renewable energy sector. The Fukuoka-based company aims to accelerate the transition to a zero-carbon economy by helping renewable energy operators manage their asset portfolios. Hori, who serves as President, has over a decade of experience in the renewable energy industry, with a background in strategic marketing and management consulting. Filter, a former strategy consultant, has focused his career on the digitization and decarbonization of energy systems.

The company's core product is Tensor Cloud, a SaaS platform that automates and optimizes the operation and financial management of solar power plants and battery storage systems. This AI-driven platform provides end-to-end support for power producers, from planning and development to asset management and operations. Key features include high-precision power generation forecasting, automated electricity market trading, revenue management, and battery storage optimization to maximize profitability. By integrating these functions, Tensor Cloud addresses operational complexities, reduces risks related to supply-demand imbalances, and enhances revenue for asset owners. The platform is designed to aggregate distributed energy resources, which is increasingly important as Japanese energy regulations undergo reforms to allow smaller-scale systems to participate in the market.

Tensor Energy operates on a B2B SaaS model, targeting renewable energy developers, power generation companies, and their financiers. The business is positioned to capitalize on Japan's push to increase its energy self-sufficiency and reduce its reliance on imported fuels. The country's energy market is shifting from fixed-price incentives to market-driven competition, creating a need for sophisticated management tools to handle the complexities of a liberalized and decentralized grid. The company has announced plans to expand beyond its SaaS model by leveraging its data to acquire and manage its own portfolio of power plants, potentially creating energy asset funds.

As of April 2026, Tensor Energy has raised approximately $10.7 million (1.7 billion yen) in total capital. A recent Series A funding round secured $6 million (950 million yen), led by Global Brain with participation from existing investors Globis Capital Partners and Delight Ventures. This capital is intended to enhance the Tensor Cloud platform, expand the global team, and support the company's move into direct energy asset management. The company serves major infrastructure and financial firms and has gained traction among leading power producers in Japan.
