Vensum Power, a Helsinki-based developer of Software-Defined Power Conversion (SDPC) solution, has closed a €9 million Series A round.
The round was co-led by existing backer Lifeline Ventures alongside two new investors, Larsen & Toubro Group and Eviny Ventures. The round also saw continued participation from investors Grid.vc and Harjavalta Ventures. Vensum Power had raised €3.8 million Seed funding in 2023, and the Series A round brings its total funding to €15.2 million since its founding in 2018.
“Data centres are competing with every other sector for the same grid capacity, and Vensum Power tackles one of the most overlooked inefficiencies in the system: converting power into a form that equipment can use optimally,” said Prashant Chiranjive Jain, Managing Director of L&T Vyoma and Head of L&T Electronic Products & Systems, both business verticals of Larsen & Toubro.
He added, “The global energy transition and the growth of digital infrastructure both depend on getting this right, at scale. We are proud to support Vensum Power as it scales up across global markets and, in doing so, we help accelerate the energy transition.”
Vensum Power was founded in 2018 and currently employs around 20 people. It develops power conversion technology that it describes as near-lossless. While conventional power converters are engineered around a narrow peak-efficiency point and typically require redesign for each new application, Vensum’s product is designed to deliver high efficiency across fluctuating loads.
Vensum Power says its converters are among the world’s smallest at their power class, and engineered for use across AI data centres, EV charging stations, energy storage systems, renewable energy installations, and DC microgrids.
As electricity demand surges, driven by global electrification and AI infrastructure buildout, efficient power conversion has moved from a technical necessity to a foundational strategic need. Vensum Power is pitching its ability to deliver near-lossless power conversion as a critical advantage in environments like AI data centres, where workloads change rapidly, and every watt lost to heat must also be cooled.
The Finnish DeepTech company says it will use the fresh capital to scale its product from development to industrial-scale delivery. The company’s Software-Defined Power Conversion platform, which uses soft-switching techniques and digital control to minimise energy losses, is set to enter mass production at partner factories in 2027.
Initial products, Vensum Power says, will serve EV charging and energy storage markets, with AI data centres to follow as the next main target.
“The funding round propels us from developing technology to delivering it at industrial scale and bringing the same proven solution to AI data centres, where access to power has become the main bottleneck. The question in data centres is no longer only how powerful the chips are, but how efficiently the used electricity actually reaches them. Thanks to the software-defined approach, our converters operate consistently at extremely high efficiency even with rapidly changing loads,” said Peter Nisula, CEO of Vensum Power.
Near-lossless energy conversion has been one of the biggest challenges in the power sector; Vensum Power is advancing closer to that goal with its first products for EV charging and energy storage entering mass production. As Nisula noted, the critical question for AI data centres is not how powerful the chips are, but how efficiently the electricity actually reaches them, and if Vensum’s SDPC platform solves that at industrial scale, a problem the company is now moving to solve at scale.
