Alantra’s Energy Transition Fund, Klima, has led a €9mn Series B financing round for maxwell+spark, a leading developer of lithium-ion battery systems for industrial logistics. The round marks the first closing of the company’s Series B raise, with a second closing expected later this year.
The capital will support maxwell+spark’s expansion into Europe and the United States, enabling wider adoption of its modular, intelligent, and cost-efficient energy solutions that replace fossil fuel power in sectors such as warehousing, refrigerated transport, and construction.
Founded in South Africa in 2017 and now headquartered in the Netherlands, maxwell+spark has become a global leader in sustainable power for industrial logistics. With operations in South Africa, the United States, and the European Union, the company’s technology has been deployed across fleets worldwide, delivering measurable cost savings and operational resilience.
Clinton Bemont, CEO of maxwell+spark, said: “Our mission is to deliver straightforward, intelligent, and cost-efficient energy solutions for industrial logistics. Since 2017, we have demonstrated through fleet analysis and real-world performance that our quiet and reliable lithium-ion systems can effectively replace fossil fuel power.”
Arfa Karani, Investment Manager at Alantra’s Energy Transition Fund, Klima, added: “Decarbonizing industrial logistics is essential to reducing global emissions, yet solutions for this sector have lagged behind. maxwell+spark has proven that intelligent, reliable battery systems can deliver real performance and cost savings at scale. By leading this round, Klima is supporting a company that is well-positioned to accelerate the transition to cleaner and more resilient energy in a hard-to-abate sector.”
The financing round brings maxwell+spark into Klima’s growing portfolio of high-growth energy transition companies, which includes MainSpring Energy, Meteomatics, Sunroof, Dexter, Echandia, Enmacc, Eturnity, GridBeyond, and SWTCH Energy. The investment follows Klima’s recent lead role in Dexter’s financing round, supporting the Dutch supplier of AI-driven energy trading and battery optimization services in its expansion into key European markets.
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, the fund is also supported by prominent institutional investors, including the European Investment Fund, the Canadian Pension Fund, and Axis ICO.
