Amsterdam, 2 July 2025 – Alantra’s energy transition fund, Klima, has led a €23mn Series C funding round in Dexter Energy, a Dutch climate tech company pioneering AI-based forecasting and trade optimization for renewables and batteries. The round was also backed by Mirova, and existing investors ETF Partners, Newion, and PDENH.
Founded in 2017 and based in Amsterdam, Dexter Energy supports clean energy transition through advanced machine learning tools for short-term power trading. Its AI-powered Trading as a Service (TaaS) platform helps renewable energy producers and battery operators navigate Europe’s increasingly complex and volatile electricity markets.
The new capital will enable Dexter to fast-track the development of its AI-driven battery optimization services, enhance its trading strategies for wind and solar portfolios, and expand operations into key European markets. Dexter’s technology is already active in the Netherlands, Belgium, and Germany, where its asset-backed optimization solutions dynamically manage production across day-ahead, intraday, and imbalance markets.
Iñigo Echaniz, Partner at Alantra’s energy transition fund, Klima, said: “Dexter Energy exemplifies the kind of cutting-edge energy tech we seek to invest in at Klima: solutions that combine advanced AI with deep energy market expertise to drive real impact. Their ability to optimize renewable and battery trading in and across multiple complex markets will be critical as Europe scales its clean energy infrastructure.”
Luuk Veeken, CEO and founder of Dexter Energy, added: “We’re excited to welcome Klima aboard. They share our belief that AI is now essential infrastructure for an electricity grid powered by renewables and storage. This investment enables us to scale our technology and redefine how clean energy is traded across Europe.”
The financing round brings Dexter Energy into Klima’s growing portfolio of high-growth energy transition companies, which includes MainSpring Energy, Meteomatics, Sunroof, Echandia, Enmacc, Eturnity, GridBeyond, and SWTCH Energy. The investment follows Klima’s recent lead role in Echandia’s financing round, supporting the leading Swedish supplier of maritime battery systems in its global expansion.
Klima, Alantra’s €210mn energy transition fund, targets technology-driven companies accelerating the shift to a net-zero energy system. Backed by Alantra and Enagás as sponsors, the fund is also supported by prominent institutional investors, including the European Investment Fund, the Canadian Pension Fund, and Axis ICO.
