Headquartered in Central Europe, HyperBunker designs and manufactures a hardware-based, network-isolated box that continuously syncs snapshots of an organisation’s most sensitive data while remaining completely offline and unreachable by threat actors or human error. The founders, CEO Boštjan Kirm and CTO Nino Eskič, conceived the product after helping customers recover from more than 50,000 ransomware incidents and seeing attackers routinely destroy connected backups first. Unlike cloud or tape solutions, the HyperBunker unit is software-free and air-gapped, positioning it as a last-line guarantee that data can be restored even if all other defences fail. Early market response has created a production-capacity bottleneck, which the team plans to address with new capital. Near-term priorities include scaling hardware output, expanding deeper into European enterprises, and launching strategically in the US. Following the latest seed round, management disclosed a post-money valuation of €4.8 million, but no revenue or customer count figures were provided.
