Zurich’s BTRY raises €4.9 million as Switzerland enters the solid-state battery race
Swiss start-up BTRY AG has closed an oversubscribed Seed round of €4.9 million to advance its ultra-thin solid-state batteries. These batteries are designed to deliver fast charging, high temperature stability, and intrinsic safety within an exceptionally compact format.
The funding round was led by Redstone VC, with Bloomhaus Ventures, Linear Capital, Kickfund, Kick Foundation, and CustomCells founders Leopold König and Torge Thönnessen joining as new investors. 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.
Growing European battery innovation
Across Europe, several start-ups are strengthening the battery value chain:
- Estonia’s Jälle Technologies raised €2 million to boost battery recycling and upcycling materials.
- Sweden’s DREV secured €2.8 million to scale contamination-control systems for battery production sites.
- Germany’s Terra One obtained €150 million to expand grid-scale energy storage capacities.
Summary
BTRY’s successful seed round underscores Switzerland’s growing role in the global solid-state battery race and the strong investor confidence driving Europe’s clean-tech sector forward.
