Vensum Power Secures €9M to Scale Power Conversion

The big picture: Finnish deeptech company Vensum Power has secured €9 million in a Series A funding round. The investment, co-led by Lifeline Ventures, Larsen & Toubro Group, and Eviny Ventures, will support the mass production of its power conversion technology and its expansion into AI data centers. This new funding brings Vensum Power’s total capital raised to €15.2 million.

Why it matters:

• Growing Demand: As electricity demand continues to rise, particularly from sectors like electric vehicles and AI data centers, reducing energy losses during power conversion is increasingly critical.
• Efficiency Imperative: Vensum Power’s software-defined approach enables its converters to maintain high efficiency even with rapidly changing electrical loads, optimizing the use of available power capacity.
• AI Data Center Focus: The company is specifically targeting AI data centers, where escalating electricity requirements and power availability constraints necessitate more efficient electricity delivery to computing infrastructure.

How it works:

• Software-Defined Platform: Vensum Power develops a software-defined power conversion platform designed to significantly reduce electricity losses during the conversion process.
• Consistent High Efficiency: According to CEO Peter Nisula, the company’s converters operate consistently at extremely high efficiency, even under rapidly changing loads, a key advantage in dynamic environments.
• Broad Application: The technology is intended for diverse applications, including electric vehicle (EV) charging, energy storage systems, DC microgrids, and the demanding power infrastructure of AI data centers.

The catch: Transitioning from technology development to industrial-scale mass production presents significant operational and financial challenges. While Vensum Power’s technology addresses a critical need for energy efficiency, the power conversion market is competitive, requiring robust execution to capture market share in both established (EV charging, energy storage) and emerging (AI data centers) segments.
