Vensum Power raises €9 million for 2027 mass production

By Grace Kim

Vensum Power has secured a €9 million Series A round to move its Software-Defined Power Conversion (SDPC) platform toward industrial-scale delivery. The Helsinki-based company said the financing lifts total funding since its 2018 founding to €15.2 million.

Lifeline Ventures, an existing backer, co-led the round with new investors Larsen & Toubro Group and Eviny Ventures, Vensum Power said. Existing investors Grid.vc and Harjavalta Ventures also participated. The deal follows €3.8 million in seed funding raised in 2023.

How will the €9 million change Vensum Power?

Vensum Power said it will use the fresh capital to scale its SDPC platform from development to industrial-scale delivery. The company, founded in 2018, employs around 20 people. Its platform is set to enter mass production at partner factories in 2027.

Initial products will serve EV charging and energy storage markets. AI data centres will follow as the next main target, Vensum Power said.

On the company’s current plan, factory production starts with EV charging and storage.

Why does Vensum see AI power demand as an opening?

Vensum Power links rising electricity demand to global electrification and AI infrastructure buildout. The company describes efficient power conversion as both a technical necessity and a foundational strategic need. In AI data centres, it says workloads change rapidly and every watt lost as heat must also be cooled.

Prashant Chiranjive Jain, Managing Director of L&T Vyoma and Head of L&T Electronic Products & Systems, both business verticals of Larsen & Toubro, said:

“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.

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’s pitch links constrained grid capacity and changing AI loads to a larger market for efficient power conversion.

How does its software-defined converter work?

Vensum Power says its power conversion technology is near-lossless and describes near-lossless conversion as one of the power sector’s biggest challenges. Conventional converters are engineered around a narrow peak-efficiency point and typically require redesign for each new application, Vensum Power said. The company says its product is designed to deliver high efficiency across fluctuating loads.

The SDPC platform uses soft-switching techniques and digital control to minimise energy losses, Vensum Power said. The company also says its converters are among the world’s smallest at their power class.

Vensum Power has designed the converters for:

• AI data centres
• EV charging stations
• Energy storage systems
• Renewable energy installations
• DC microgrids

The technical pitch is stable efficiency and compact hardware across changing loads and multiple markets.

Can the platform scale into AI data centres?

Peter Nisula, CEO of Vensum Power, said:

“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.”

The next test comes in 2027, when partner factories are due to begin mass production. Vensum then has to show that a platform built for EV charging and storage can deliver the same high efficiency in AI data centres, where Nisula says access to power has become the main bottleneck.
