Munich, Germany - 17.12.2025 - ZeroPhase GmbH, the company building software-defined, mission-proven data links for unmanned defense platforms, has raised €5.8 million in an oversubscribed seed round led by BlueYard Capital, with participation from multiple Business Angels. The funding accelerates development and deployment of ZeroPhase’s adaptive communication layer - high-performance, resilient connectivity that preserves sovereign control of critical links across air, land, and sea.

“Communication is the nervous system of defense, communication decides outcomes,” said Dr. Florian Petit, CEO of ZeroPhase. “Our goal is to ensure it never fails. And with the support of Blueyard, we’re building adaptive data links that deliver uncompromising performance and reliability - adaptable across domains and mission types, forming the foundation of trusted connectivity for the unmanned systems of tomorrow.” 

Unmanned defense systems rely on robust, low-latency communication to transmit video, telemetry, and command data under demanding conditions. The number of these systems in operation is expected to exceed 4.5 million units in Ukraine alone in 2025, making secure and stable data links more critical than ever. ZeroPhase’s data links dynamically adapt to jamming, interference, and signal degradation-ensuring mission continuity and trusted, sovereign connectivity where failure is not an option.

ZeroPhase’s technology is already deployed at scale, operating daily in Ukraine and supporting thousands of unmanned missions. Extensive field use under real combat conditions has validated the company’s ability to maintain high-performance communication even under electronic attack and degraded network conditions. Experts estimate that today’s electronic-warfare systems can disable unprotected drone communications in a matter of seconds - highlighting the critical importance of secure and adaptive data-link technology.

“ZeroPhase's technology has proven to be a key enabler. Its adaptive protocol, when integrated into our custom-developed UAV systems and deployed by our expert field teams, has allowed us to maintain communications in the most extremely jammed environments on the frontline - areas where other drones simply cannot fly.” - UAV Operations Lead, Ukraine

With this new funding, ZeroPhase will expand its engineering and signal-processing teams, deepen partnerships across the European defense and aerospace ecosystem, and extend its adaptive communication framework to additional mission profiles and operational domains.

“At BlueYard, we back technologies that move us toward utopia and those that hold the line against oblivion,” said Michael Wax, Partner at BlueYard Capital. “ZeroPhease does both. By securing the invisible layer that allows unmanned systems to communicate and coordinate, they help ensure that free societies can act with confidence. Their systems already prove it daily in Ukraine—built by a team whose clarity, rigor, and purpose deeply impressed us.”
