Vensum Power raises €9M to slash power waste in AI data centres

€9M Series A fuels shift to mass production

Helsinki-based Vensum Power has closed a €9 million Series A round to bring its software-defined power converters to market. The round was co-led by Lifeline Ventures, Larsen & Toubro Group and Eviny Ventures, with follow-on investment from existing backers Grid.vc and Harjavalta Ventures. The fresh capital pushes Vensum’s total funding to €15.2 million since its 2018 launch.

The money will move the company from prototyping to industrial-scale production. Vensum expects to begin mass production in 2027, starting with EV chargers and energy-storage systems before expanding into AI data centres.

Vensum’s converters cut electricity losses during power conversion. That matters most in AI data centres, EV charging and renewable-energy installations, where every percentage point of efficiency translates into megawatts saved. The hardware stays efficient even when electrical loads fluctuate rapidly—a common issue in AI clusters.

CEO Peter Nisula called the round a turning point. “The question in data centres is no longer only how powerful the chips are,” he said. “It’s now about how efficiently the electricity actually reaches them. This funding lets us shift from development to large-scale delivery.”

Larsen & Toubro’s Prashant Chiranjive Jain, who runs L&T Vyoma and the Electronic Products & Systems division, said the deal aligns with the global energy transition. He added that Vensum’s platform answers the urgent need to optimise power conversion at industrial scale.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

Vensum Power’s €9 million round shows that energy efficiency is no longer a side metric—it’s now a board-level priority for data centre operators. By slashing conversion losses, the company gives them a way to meet AI-driven power demand without tripling their grid connections.

Key takeaways

• The €9 million Series A is co-led by Lifeline Ventures, Larsen & Toubro Group and Eviny Ventures, pushing Vensum Power’s total funding to €15.2 million.
• Mass production starts in 2027; EV charging and energy storage are first, AI data centres follow.
• Vensum’s converters keep efficiency high even when loads swing rapidly—a key pain point for AI data centres.
• Larsen & Toubro’s participation signals industrial muscle behind the scale-up.
