Bihar Batteries — Pre-seed (estimated) · €600K

This was the company's first private investment round. ESS News says it closed in 2024, but no month is given, so the date is set to 2024-01 as a year-only placeholder. On 12 September 2025, SPRI reported €600K of private funding secured to date and did not name any investors. That figure may be the total raised so far rather than this one round. Around the same time, the company received grants rather than rounds: the Ekintzaile grant from SPRI and the Gipuzkoa Provincial Council, and Hazitek funding from SPRI.
