Ransomware has become an industrial-scale digital threat. In the UK alone, 19,000 successful attacks were reported in the past year, double the previous total. Traditional cloud backups, despite being everywhere, are increasingly easy pickings for threat actors: attackers know that connected storage is the first place to hit for maximum chaos. That’s the landscape that pushed a pair of seasoned data recovery experts to rethink the whole concept of digital protection, and it’s how HyperBunker was born.
Headquartered in Central Europe and already starting its expansion into the US and broader EMEA region, HyperBunker today locked down €800,000 in seed financing, led by Fil Rouge Capital and Sunfish Venture Capital. Boštjan Kirm, CEO of HyperBunker, confirmed to TFN, “To date, post-money valuation is €4,8 million.”
Giving organisations an immutable, air‑gapped “bunker” for their most critical data
The company’s founders, CEO Boštjan Kirm and CTO Nino Eskič, began building HyperBunker after years of helping customers recover from over 50,000 ransomware events.
Kirm noted, “Our founders discovered a systematic problem after recovering data from more than 50,000 cases: even most protected enterprises were losing data as a result of attackers focusing on backups first. The goal was obvious: to create an offline, physical layer that is impenetrable. As a last resort that ensures restoration even in the event that every digital system fails, not as an additional better backup.”
That hands-on experience shaped their mission: to eliminate the dependence on connected cloud systems and give organisations an immutable, air‑gapped “bunker” for their most critical data. Their vision centres on assuming compromise rather than denying it, and designing protection that remains functional even when other systems fail.
Unlike Datto, Acronis, and Veritas, HyperBunker’s core product is a sealed, air-gapped box: network-isolated, software-free, and fundamentally unreachable by outside threats or human error. The system automatically syncs critical data across snapshots, but its isolation ensures it is always safe as a last line of defence.
Kirm added, “HyperBUNKER guarantees that data can be restored in the event that conventional backups and cybersecurity technologies malfunction. The closest analogy would be tape systems, but without the operational difficulties, hold-ups, and reliance on humans.”
What’s next?
With the new capital, HyperBunker aims to ramp up its hardware-constrained production and meet ballooning market demand. The company’s next targets include deeper expansion across European enterprises and a strategic push into the US, where ransomware is keeping CIOs up at night.
“Hyperbunker’s bold mission to neutralise ransomware addresses one of the most urgent global threats to national security and critical infrastructure. Their deep-tech solution, shaped by insights from over 50,000 real-world data recovery cases, represents an innovative shield against one of the most dangerous digital weapons of our time. For us, this is the perfect combination: a critical global priority, a breakthrough technology, and a founding team with unmatched domain expertise,” said Max Moldenhauer, partner at Sunfish.vc.“
With a real answer for ransomware based on over 50,000 data recovery cases and a production capacity-constrained pipeline for their product, we had to participate in funding the team at HyperBunker. Market response to their unique solution has been extremely positive. We are happy to partner with the team to scale up their business,” stated Dr. Ales Pustovrh from Fill Rouge Capital.
