Vensum Power has closed a €9M Series A to push its software-defined power conversion platform into mass production, with AI data centres now central to the plan.
Lifeline Ventures, Larsen & Toubro Group and Eviny Ventures co-led the round. Total capital raised now stands at €15.2M.
The loss nobody prices
Power conversion, the step between grid electricity and whatever a chip or battery needs, always loses some energy as heat. Vensum’s approach replaces fixed hardware behaviour with software control, keeping converters efficient even when electrical loads swing quickly.
That stability matters more as loads become erratic. AI training clusters draw power in sharp bursts, and grid connections are increasingly the binding constraint on data centre expansion.
Chief executive Peter Nisula frames the problem in blunt terms: the question is no longer only how powerful the chips are, but how efficiently the electricity actually reaches them.

Mass production is slated for 2027, spanning EV charging, energy storage and DC microgrids. Data centres are the newer and more lucrative target.
Backing from Larsen & Toubro, an Indian engineering conglomerate, hints at manufacturing and market reach beyond the Nordics. Eviny Ventures brings Norwegian utility exposure.
Vensum is competing against established power electronics incumbents with decades of installed base. Its bet is that software flexibility beats specialised silicon as workloads fluctuate.
