War turned Kyiv into a cybersecurity lab. Its tools get tested under real attack. Defence and cyber pulled fresh money in 2025. A tight group of VCs and funds backs them. Here are 14 investors funding Kyiv cybersecurity in 2026.
Kyiv now builds security under constant real attack. That pressure makes its cyber tools truly battle-tested.
Defence and cyber startups raised fresh money in 2025. Over a hundred million went into defence tech alone.

War made Kyiv a proving ground
Real war makes Kyiv security tools fully battle-tested. Buyers trust gear that has already survived attacks.
Founders ship fast and learn straight from the front line. That speed is very hard for outside rivals to match.
Investors really prize this real-world proof of value. Track who studies your proof with document analytics.
Run a clean IT due diligence prep well before pitching. Ellty logs every file an investor opens and reads.
Dual-use is the funding sweet spot
Dual-use tools sell to both armies and to companies. That double market clearly widens your buyer base.
Investors like the softer regulatory risk in dual-use. Pure military tech often faces harder export limits.

Keep contracts and your proof ready for due diligence. Ellty logs every investor who opens your data room.
Vet partners well with our vendor due diligence guide. Strong partner checks reassure cautious cyber funds.
