€14 million to make the fastest-to-produce battery in the world a reality

The financing consists of approx. €8 million in non-dilutive grants and around €6.4 million in investment. This exceptionally high level of funding at such an early stage of a technology company signals the strategic relevance of Unbound Potential’s technology for the future of energy storage and sets a new benchmark in the European battery scene.

The investment round was led by renowned investors, including Founderful as lead investor, Kvanted as co-lead, and Zürcher Kantonalbank (ZKB). Unbound Potential is also supported by significant funding from SPRIN-D, Innosuisse, the Migros Pioneer Fund, and the City of Zurich’s KlimUP initiative.

“Unbound Potential is at the forefront of industrial transformation, and its battery technology solves one of the greatest challenges of our time: the reliable storage of renewable energy. The feasibility of the technology and approach as well as robust supply chains are clear advantages here.”, says Eerik Paasikivi, Founding Partner of Kvanted.

“By 2040, the world will need three times more batteries than supply can deliver. Early pilots with AI datacenters, EV fleet operators, and grid players confirm market pull and urgency. Unbound Potential has created the simplest, fastest-to-produce battery in the world. As demand outpaces supply, availability—not just innovation—will drive the energy transition”, adds Antonia Albert, Principal at Founderful.

David Taylor, founder and CEO of Unbound Potential: “With €14.4 million, we have completed one of the largest pre-seed financing rounds in Europe. The round is a decisive step for us as a company and a strong signal for our vision of a future based entirely on renewable energies. With the capital, we can now accelerate the development of our membrane-free redox flow technology and demonstrate its scalability in initial pilot projects.”

Unbound’s redox flow battery technology enables rapid and cost-effective scaling of stationary energy storage systems. By storing energy in two liquid electrolytes, the technology bypasses the complex and expensive manufacturing steps involved in conventional batteries, finally making scalable electrochemical storage a reality. Compared to conventional redox flow batteries, the membrane-free system enables lower-maintenance operation and significantly lower investment costs.

The effectiveness of the technology will be tested in high-profile projects. Companies like Amazon are working with Unbound Potential to test if the technology can play a major role in the electrification of logistics services. Also, the company is in discussion with FlexBase, which is developing Europe’s largest redox flow energy storage project at the “Star of Laufenburg.” An initial pilot plant will go into operation in mid-2026 at the site of a local pilot partner.
