Swiss battery start-up BTRY AG secured €4.9 million in an oversubscribed seed funding round aimed at advancing its ultra-thin solid-state batteries. These batteries are designed to offer fast charging, stability across extreme temperatures, and high safety in a compact format.
The funding round was led by Redstone VC, with participation from Bloomhaus Ventures, Linear Capital, Kickfund, the Kick Foundation, and the CustomCells founders Leopold König and Torge Thönnessen. Existing backers HTGF (High-Tech Gründerfonds) and Zürcher Kantonalbank (ZKB) also renewed their support.
“The oversubscribed round confirms strong investor confidence from experienced DeepTech and industrial backers. Working closely with this international consortium will enable us to transform world-class research into a scalable product,” said Dr. Moritz Futscher, CEO and co-founder of BTRY AG.
Across Europe, battery innovation continues to accelerate. Estonia’s Jälle Technologies raised €2 million to advance recycling and upcycling of battery materials. Sweden’s DREV secured €2.8 million to enhance contamination-control systems for battery manufacturing, while Germany’s Terra One obtained €150 million to expand grid-scale energy storage capacity.
BTRY AG’s €4.9M funding signals Switzerland’s growing involvement in the solid-state battery field and the broader European drive to challenge Asian market dominance.
