Vensum Power lands €9M to expand its power converters for AI data centres

Vensum Power, a Helsinki-based startup that makes software-controlled power converters, has raised a €9 million Series A round. The round was co-led by Lifeline Ventures, Larsen & Toubro and Eviny Ventures. The company's pitch is about efficiency: every time electricity is converted, some of it is lost as heat, and Vensum uses software to control its converters. It says its technology will reduce power losses in the worst case, and it is now looking at Nvidia's 800V data centres as a next target.

The main purpose of the funding is to start manufacturing and move into volume production. Revenue is expected in 2027. Vensum's customers are converter OEMs, all of them outside Finland.

The company has 20 employees and is hiring. The team is based in Helsinki and is predominantly Finnish.

With this round, Vensum has raised €15.2 million in total. That includes a €3.8 million seed round in May 2023, led by Lifeline Ventures, Grid.vc, Harjavalta and Business Finland.

Vensum is part of Finland's deep tech sector, which, according to Business Finland, attracted $1.5 billion in venture capital funding in 2024. The round is a sign of continued investor interest in power electronics aimed at AI data centres, where cutting conversion losses is a central concern.
