Dutch climate tech startup Dexter Energy raises €23M to scale AI-powered renewable trading

Amsterdam-based climate tech startup Dexter Energy has raised €23 million ($27.1 million) in Series C funding to scale its AI-driven forecasting and trading tools for renewable energy and battery operators. The round was led by Alantra’s Klima fund, with participation from Mirova and continued backing from ETF Partners, Newion, and PDENH.

The fresh funding will fuel Dexter’s expansion across European energy markets, where the company is helping producers boost returns using AI that predicts pricing, demand, and output with greater accuracy.

Founded in 2017 by Luuk Veeken (CEO), Hubert Penn (CCO), and Tom Lemmens (CPTO), Dexter helps energy producers get more out of their renewable assets by optimizing how and when they trade power. Its AI-driven software automates trading across day-ahead, intraday, and imbalance markets, adjusting strategies in real time. By tapping into physical flexibility—like curbing output or managing storage—Dexter gives operators tighter control and better timing, which can lead to significantly higher revenues.

Since its inception eight years ago, Dexter has focused on the Netherlands but plans to use the fresh capital to grow across more European markets.

“We’re excited to welcome Klima aboard. They share our belief that AI is now essential infrastructure for an electricity grid increasingly powered by renewables and storage,” said Luuk Veeken, Dexter’s founder and CEO.

Veeken added, “This investment enables us to grow our team, expand into new markets, and redefine short-term trading for wind, solar, and battery portfolios. In doing so, we can help more companies get the most out of their clean energy and support them in balancing the grid.”

Dexter says its forecasting software helps producers increase wholesale market revenues by as much as 30%. The technology pulls in data from over a dozen external sources, including weather models and market prices, to predict energy supply and demand more accurately.

Dexter’s latest funding reflects growing investor interest in tools that bring more precision and financial returns to renewable energy as countries across Europe work to modernize their grids.

With demand for clean energy climbing and volatility becoming the norm, there’s a clear opening for tools that help energy companies make better calls. Dexter is betting that AI—when fed the right data—can give producers a much-needed edge.
