Ukrainian defense technology company MaXon Systems has drawn the attention of global venture investors, with U.S.-based Green Flag Ventures announcing an investment in the startup developing autonomous systems to counter large-scale drone swarm attacks.
The project addresses one of the key challenges of modern warfare — mass swarms of hostile drones increasingly used to target civilian and critical infrastructure. Instead of relying on costly traditional air defense systems or manual interception, MaXon is developing a closed-loop, autonomous defense platform that combines:
- high-speed interceptors capable of responding to multiple targets;
- long-range detection and tracking systems monitoring drone movement over significant distances;
- integrated software for automatic guidance and targeting.
The technology has reached Technology Readiness Level (TRL) 8 and has been successfully validated in real combat conditions, positioning it among the most advanced Ukrainian developments in the DefenseTech sector.
MaXon Systems plans to further develop the platform in several key areas:
-
full autonomy across all stages of interception, from launch to terminal phase;
-
remote command center control of multiple interceptors simultaneously;
-
integration of radar-guided targeting to enable operation in all weather conditions.
According to investors, architectures prioritizing autonomy are expected to shape the future modernization of air defense systems in Europe and NATO countries over the coming decade.
The deal size has not been officially disclosed. However, according to public sources, typical ticket sizes for Green Flag Ventures range from $100,000 to $1 million.
Other investors joining Green Flag Ventures include the BRAVE1 venture cluster, Freedom Fund VC, Big Defence, and additional partners.
Earlier, in August 2025, MaXon closed its first funding round of approximately $350,000 with participation from Freedom Fund and Defender Ventures.
The investment represents one of the most significant recent international endorsements of Ukrainian defense technologies and reflects growing interest from Western capital in combat-proven products with potential integration into future EU and NATO security ecosystems.
