Voltfang, a leading provider of European battery storage solutions for industrial, commercial, and grid-scale applications, has successfully closed its Series B financing round, raising €15 million.
The round was once again led by Dutch deeptech investor FORWARD.One. Additional investors include existing backers such as Interzero, PT1, Helen Ventures, Daphni, Aurum Impact (the Goldbeck family office), as well as new partners like Fiege Ventures and Newberry Investments.
With this new capital, Voltfang aims to significantly scale its production capacities and deliver an additional 250 megawatt-hours of sustainable battery storage across Europe by the end of 2026. The company will also continue developing its intelligent energy management system, Venma, which integrates AI capabilities to help businesses maximize self-consumption, lower electricity costs, and participate in energy markets.
Voltfang’s systems use high-performance, requalified battery modules sourced from the European automotive industry—contributing to energy security and a more resilient energy infrastructure. The company’s oversubscribed Series A round in 2024 underscored strong investor confidence in Voltfang’s mission to deliver sustainable and scalable battery storage solutions for Europe’s energy transition.
David Oudsandji, CEO and Co-Founder of Voltfang, commented:
“This financing round directly responds to the enormous surge in orders we experienced in Q1. Expanding the energy infrastructure is urgently needed across Germany and Europe, especially as we work to build resilience against external energy dependencies. We must act now to create more grid flexibility using large-scale battery storage. Doubling our company valuation in just six months is a strong signal of the market’s confidence in Voltfang’s technological relevance and growth potential.”
Paul Pruijmboom, Partner at FORWARD.One, added:
“Voltfang perfectly embodies our investment strategy: strong hardware paired with intelligent software. With their powerful and truly European storage technology, the team is tackling one of the most pressing challenges of our time—enabling the energy transition. We firmly believe that local energy infrastructure will be a key pillar of Europe’s future economic growth.”
Niko Samios, Partner at PT1:
“We’ve supported Voltfang since their seed round and are impressed by how consistently the team has executed their vision. Their focus on circular economy principles and green storage solutions addresses the critical challenges of the energy transition. This successful Series B highlights the market relevance and scalability of their business model—we’re proud to be part of the journey.”
Jens Fiege, CEO of the Fiege Group:
“Voltfang provides logistics companies with exactly what they need for the future: a technologically robust, environmentally sound, and economically scalable solution. With our investment, we’re not only providing capital—we’re also bringing our infrastructure and expertise to the table to help advance efficient energy storage in logistics.”
“Combining circular economy principles, energy management, and scalable storage technology, Voltfang addresses exactly the challenges facing both the building sector and the energy supply system. For us, they’re a key partner in creating integrated building and energy solutions”,
says Jan-Hendrik Goldbeck, Managing Partner at GOLDBECK.
“Voltfang has built a business model that is not only technologically convincing but also economically sound and forward-looking”,
adds Miki Yokoyama, Managing Director at Aurum Impact (Goldbeck Family Office).
