Vensum Power raises €9M Series A to cut power losses in AI data centres

Efficiency under changing loads

As electricity demand keeps growing, losses during conversion matter more. Vensum Power says its software-defined approach lets its converters stay highly efficient even when electrical loads change rapidly, which helps operators make better use of the power capacity they already have.

The company is now also targeting AI data centres, where rising electricity needs and limited power availability create extra pressure. Its technology is meant to improve how efficiently electricity reaches computing infrastructure, so facilities can get more from their existing capacity.

CEO Peter Nisula said the funding marks the move from technology development to industrial-scale production, and opens the door to AI data centre applications. "The question in data centres is no longer only how powerful the chips are, but how efficiently the used electricity actually reaches them," he said. Thanks to the software-defined approach, he added, the converters operate consistently at extremely high efficiency even with rapidly changing loads.

What comes next

With the new capital, Vensum Power plans to bring its power conversion platform into mass production in 2027. It will first target EV charging, energy storage and DC microgrids, while extending the technology into the AI data centre market.
