Finnish deeptech startup Vensum Power said on November 6, 2026 that it raised a €9 million Series A to move its software-defined power-conversion platform into mass production in 2027. The round was co-led by Lifeline Ventures, Larsen & Toubro Group and Eviny Ventures, bringing the company’s reported total capital raised to €15.2 million.

What did Vensum Power announce?

Vensum Power announced on November 6, 2026 that it raised a €9 million Series A to support its move from technology development into industrial-scale production. Tech.eu reported that the round was co-led by Lifeline Ventures, Larsen & Toubro Group and Eviny Ventures.

The Helsinki-based company develops a software-defined power conversion platform, which it says uses soft-switching and digital control to cut conversion losses and adapt to changing loads and input voltages. The startup says its approach is designed to keep converters highly efficient even when operating conditions shift rapidly.

What does Vensum Power’s technology do?

Vensum Power says its platform, called Software-Defined Power Conversion, is meant to improve how electrical power is converted and delivered to demanding infrastructure. On its website, the company says conventional converters are optimized around a narrow peak-efficiency point and are typically designed from scratch for each application, while its software-defined approach aims to make the hardware more adaptable.

Tech.eu reported that the company’s technology is intended for EV charging, energy storage systems and DC microgrids first, with AI data centres coming later. The publication said Vensum Power is targeting AI data centres to improve the efficiency of electricity delivery to computing infrastructure, where every percentage point of conversion loss can affect operating costs and capacity planning.

Tech Funding News reported that Vensum Power describes its conversion process as "near-lossless," a self-described performance claim not independently verified. The company’s own materials say the system uses soft-switching to reduce losses and digital control of the conversion process to maintain efficiency under changing loads and input voltages.

How will the new capital be used?

The company said the financing will help it transition to mass production in 2027. Tech.eu reported that the new round is intended to support the scale-up of Vensum Power’s power-conversion technology, while Tech Funding News said the funding will support volume production of software-controlled power converters by 2027.

CEO Peter Nisula described the round as a shift from technology development to industrial-scale production, according to Tech.eu. Tech Funding News similarly attributed to Nisula that the main purpose of the round is to start manufacturing and move into mass production.

The company’s first target markets are EV charging, energy storage and DC microgrids, with AI data centres next. Tech Funding News also attributed to COO Tero Lehtonen that Vensum Power aims to improve not only best-case efficiency but especially worst-case performance.

Who is backing Vensum Power and what comes next?

The new round brings Vensum Power’s reported total capital raised to €15.2 million. Tech Funding News reported that the startup previously raised a €3.8 million seed round in May 2023, led by Lifeline Ventures, Grid.vc, Harjavalta and Business Finland. The publication also said Grid.vc and Harjavalta Ventures are existing investors.

Lifeline Ventures lists Vensum Power as a company developing software-defined power-conversion technology and identifies Peter Nisula as CEO. Vensum Power says on its website that it was founded in 2018, while Tech Funding News reported that the company was set up in 2018 by Jyrki Penttonen and Mika Marjalaakso, so the source set conflicts on the company’s founder history.

Tech Funding News said the company has 20 employees, is hiring, and is based in Helsinki with a predominantly Finnish team. It also reported that Vensum Power’s customer base is converter OEMs outside Finland and that the company expects revenue in 2027.

Tech Funding News reported that Nisula said the technology could let operators process more tokens in AI data centres, and that it can also enable smaller converters or higher power output without needing more space. The company says it plans to bring its platform into mass production in 2027 before extending further into AI data centres.
