Osavul raises €8.5M Series A to expand hybrid threat intelligence

Osavul, an AI startup that spots state-backed attacks before they happen, has raised €8.5M in a Series A round.

33N Ventures, a European cybersecurity fund, led the round, and it brings the total Osavul has raised to about €12m.

Balnord, G+D Ventures and earlier backer 42CAP also put in money. Osavul now runs from London and Luxembourg.

The company was founded in Kyiv in 2022, after Russia’s full-scale invasion of Ukraine. It began by tracking Russian disinformation for Ukrainian security bodies. It has since moved on to what it calls hybrid threats.

These are campaigns that mix cyberattacks, sabotage, spying and online manipulation. Osavul’s AI scans public and private data for early signs that a group is going after a client. It then maps those signs to the client’s staff, sites and suppliers to show where a strike could land.

Human analysts check each report, and the system can run on a client’s own servers, so data stays in-house. Osavul says it works with state, defence and security bodies in more than 10 countries, including the UK, Germany, Poland and the US.

Osavul also works for NATO. It is one of the partners in the Brandwatch and Blackbird.AI consortium that NATO picked this year to monitor the information space.

The company plans to sell to firms that run energy, transport, ports and banks, while it keeps its state work. And they say the total value of its contracts grew fourfold in 2025.

“Hybrid attacks are no longer a government problem alone,” said Dmytro Plieshakov, Osavul’s co-founder and chief executive.

Plieshakov founded the company with Dmytro Bilash, its chief business development officer. According to Balnord, the pair had already built and sold a company together before starting Osavul.

Osavul will also use the cash to improve its AI, grow its sales team and enter new markets.

“Adversaries operate across information, cyber and physical channels at once; most security tools are still siloed,” said Carlos Alberto Silva, managing partner at 33N Ventures.
