Helsinki’s Vensum Power secures €9 million to scale its software-defined power conversion platform

The round was co-led by existing investor Lifeline Ventures and new investors Larsen & Toubro Group and Eviny Ventures. Existing investors Grid.vc, and Harjavalta Ventures also participated. The company had raised €3.8 million in seed funding in 2023, bringing its total funding to €15.2 million since its launch 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.

Founded in 2018, Vensum Power has a team of around 20 people. The company develops power conversion technology designed to reduce energy loss and maintain high efficiency even when power demand changes. Unlike traditional converters, which are designed for specific operating conditions, Vensums technology can work efficiently across different loads.

The company says its converters are among the world's smallest in their power category. They are designed for use in AI data centres, EV charging stations, energy storage systems, renewable energy projects and DC microgrids.

With electricity demand rising due to AI and the growing use of electric power, efficient energy conversion is becoming increasingly important. This is especially true for AI data centres, where changing workloads require more power and cooling.

Vensum Power will use the new funding to scale up production and move its technology towards commercial delivery. Its Software-Defined Power Conversion platform is expected to enter mass production at partner factories in 2027.

“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.
