Alantra’s Energy Transition fund, Klima, has completed a $15mn Series B financing round for maxwell+spark, welcoming Chevron Technology Ventures (CTV) and Idemitsu as new strategic investors. The transaction represents the second closing of the company’s Series B round, following the initial €9mn led by Klima in September 2025.
This investment fuels maxwell+spark’s drive to electrify industrial logistics through a unified, configurable battery ecosystem that replaces diesel engines and lead-acid systems across forklifts, refrigerated transport, and backup power. Its lithium-ion systems are modular, circular, data-driven, and interconnected—underpinned by eight years of real-world performance data from thousands of deployed units. By connecting isolated machines into an integrated low-carbon network, maxwell+spark helps operators optimize cost and performance while reducing emissions.
Clinton Bemont, CEO of maxwell+spark, said: “Closing this Series B round marks a defining step for us. The backing of global energy leaders—Chevron Technology Ventures, Idemitsu, and Klima—alongside Fairtree, validates both our mission and our execution. Industrial logistics is among the toughest, most cost-driven sectors to decarbonize. This investment accelerates the reliable, intelligent, and cost-effective energy systems our customers rely on every day.”
Bastien Gambini, Managing Director of Alantra’s Energy Transition fund, Klima, added: “We’re delighted to welcome Chevron Technology Ventures (U.S.) and Idemitsu (Japan) as strategic investors in maxwell+spark. Their participation underscores the company’s technological strength and global potential. Following Klima’s initial backing in September, this second closing broadens maxwell+spark’s international reach and accelerates its mission to decarbonize energy-intensive industries through advanced electrification.”
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 assembly operations in the EU, South Africa, and the U.S., its systems are deployed across fleets worldwide, delivering measurable performance, cost efficiency, and resilience.
