Finnish maker of software-defined DC-DC power conversion technology for EV charging, energy storage and data centres.
Vensum Power Oy is a Finnish company that develops Software-Defined Power Conversion (SDPC) technology, which uses soft-switching techniques such as zero voltage switching and zero current switching, combined with predictive control algorithms, to reduce electricity losses in DC-DC power conversion.
The company's converter platform targets electrification and AI-infrastructure applications, including EV charging, battery energy storage, DC microgrids, and (in later phases) AI data centres. Vensum markets the technology as cutting conversion losses, lowering component count, and extending converter lifespan compared with conventional hardware-fixed power electronics.
Vensum Power was founded in 2018 by Jyrki Penttonen and Mika Marjalaakso. It raised a €3.8 million seed round in May 2023 led by Lifeline Ventures, and a €9 million Series A round in November 2026 co-led by Lifeline Ventures, Larsen & Toubro Group, and Eviny Ventures, to move its converters into mass production.
