Lead
Osavul, a Luxembourg-headquartered hybrid threat intelligence company, announced an €8.5M Series A on October 1, 2026. 33N Ventures led the round. Balnord, G+D Ventures and existing backer 42CAP also participated. Total funding now stands at about €12M. The company did not disclose a valuation.
The platform analyses open and privileged data to flag hostile intent across information, cyber and physical domains before an attack materialises. Osavul will spend the money on AI development, on selling to enterprises and critical infrastructure operators, and on deepening its government and defence work.
What Does Osavul Actually Sell?
Osavul sells an AI platform that links online manipulation, cyber intrusion and physical sabotage into one threat picture. Most security tooling treats those as separate problems owned by separate teams. The company argues that adversaries run them as one campaign.
The software runs on-premises inside sovereign infrastructure, a requirement for many defence and intelligence buyers. It produces assessments traced back to evidence and reviewed by analysts, rather than opaque risk scores. That design suits customers who must defend a finding in front of a minister or a regulator.
Where Did the Company Come From?
Osavul started in Kyiv in 2022, when it set out to track Russian disinformation after the full-scale invasion of Ukraine. Co-founder and CEO Dmytro Plieshakov and co-founder Dmytro Bilash, who serves as chief business development officer, built the product against a live adversary. The company later moved its headquarters to Luxembourg.
That origin gives it something many European competitors lack: operational data from a state-backed influence campaign that was running at scale. It also explains the pivot. Disinformation on its own is a hard market to monetise, while a broader threat-detection pitch reaches budgets in energy, transport and banking.
Who Is Already Paying?
Osavul works with government, defence and security bodies in more than 10 countries, including the UK, Germany, Poland and the US, according to the company. It is one of three technology companies delivering NATO's Information Environment Assessment Capability. It sits in a consortium led by Brandwatch and Blackbird.AI.
Total contract value grew fourfold in 2025. The company did not publish revenue, so the multiple is hard to size. A fourfold increase from a small base is a different claim from a fourfold increase from a large one.
Bilash framed the demand in geographic terms. "Hybrid threats right now are a very European problem," he said, adding that this is why customers show more willingness to pay.
Why Does This Round Matter for the Market?
The round shows investors will fund hybrid-threat tooling as a category separate from conventional cybersecurity. Carlos Alberto Silva of 33N said adversaries operate across information, cyber and physical channels at once, while most security tools remain siloed. That is the investment thesis in one sentence.
The competitive set is crowded and better capitalised in places. Blackbird.AI, which shares the NATO consortium with Osavul, has raised about $58M in total. Refute, LetsData and Golden Owl also work on narrative and disinformation detection. Osavul's differentiation rests on on-premises deployment, the cross-domain framing and its European sovereignty angle.
A Series A of this size is modest by defence-tech standards. It funds a focused push into new sectors, not a land grab. The harder test is whether banks, port operators and utilities buy a hybrid threat product on its own or fold it into existing security operations centre budgets.
What Comes Next?
Expect Osavul to spend on enterprise sales, where procurement cycles are shorter than in government but contract values are smaller. Winning energy, transport, ports and banking clients would reduce dependence on public budgets tied to NATO and national defence spending.
Execution risk sits in two places. Enterprise buyers need to see measurable outcomes, such as an attack that was flagged early, which is hard to prove when the point is that nothing happened. And larger incumbents in threat intelligence can add disinformation modules faster than a startup can build a sales team.
Outlook
Osavul has moved from tracking Russian narratives in Kyiv to selling cross-domain threat assessment from Luxembourg, backed by an €8.5M Series A and about €12M in total funding. NATO work and a fourfold rise in contract value in 2025 give it credibility. The undisclosed valuation and revenue leave the scale of that traction open. The next 12 months will show whether enterprise buyers pay for hybrid threat detection as a standalone product.
