Buntar Aerospace, part of the Sigma Software Labs portfolio, has closed a $16 million funding round. The round was led by Freedom Fund VC and an international private equity fund, with participation from Gardar Venture Capital, Iron Wolf Capital and Autonomy Capital. Buntar’s total funding now stands at $30 million, as reported by dev.ua citing Forbes Ukraine.
This is Buntar’s second round this year. In March, the company raised $10.4 million in a round led by Axon Enterprise, and that deal was later listed by Vestbee among the largest Ukrainian rounds of 2026. Two rounds in one year, from two different groups of investors, show that the company’s growth is being financed on its results.
What Buntar Aerospace builds
Buntar Aerospace was founded in August 2023. Its Buntar-3 reconnaissance drone is built to operate under heavy electronic warfare, and Buntar Copilot is an AI assistant that helps drone operators make decisions in combat. Both are used by frontline units across Ukraine, and together they bring the company steady, fast-growing revenue.
The company started with a single product. It is now building a business across several areas of defense autonomy: reconnaissance, counter-drone, and precision strike support.
“Our systems can fly, see and make decisions on their own, so that people can focus on what matters most. This is what Ukraine needs today, and what Europe must be ready for tomorrow,” says Bohdan Sas, co-founder of Buntar Aerospace.
Where the money goes
Buntar has named four priorities for the new capital:
- Faster R&D and continued development of Copilot
- More production capacity, as demand from the Armed Forces of Ukraine keeps growing
- Experienced engineering and management teams
- International expansion with dual-use solutions, including civilian applications
Defense tech funding in Europe
The international part of Buntar’s plan lands in a growing market. European defence, security and resilience startups raised a record $8.7 billion in 2025, up 55% year over year, according to Dealroom and the NATO Innovation Fund. AI underpinned 44% of that funding, the highest share in six years. Software that helps operators decide, like Copilot, sits right where that capital is going.
Why we back Buntar Aerospace
We invested in Buntar Aerospace because the team builds hardware and software tested in real combat conditions, not just in demos. Each new round confirms that Ukrainian defense technology can attract serious international capital, and every such deal makes the path clearer for the founders who come next.
