ZeroPhase, a German defense technology company developing software-defined, mission-proven data links for unmanned platforms, announced a €5.8 million oversubscribed seed round led by BlueYard Capital with participation from multiple business angels, supporting faster development and deployment of an adaptive communication layer that delivers resilient, high-performance connectivity across air, land, and sea while preserving sovereign control.
“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 platforms depend on low-latency, secure communications to transmit video, telemetry, and command data in contested environments, with millions of systems expected to be active in active conflict zones by 2025. ZeroPhase technology dynamically adapts to jamming, interference, and signal degradation, ensuring mission continuity where conventional links fail.
ZeroPhase systems are already deployed at scale, operating daily in Ukraine and supporting thousands of unmanned missions, with real-world combat use validating performance under electronic warfare and degraded network conditions where unprotected communications can be disrupted within seconds.
“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
The new capital will be used to expand engineering and signal-processing teams, strengthen partnerships across the European defense and aerospace ecosystem, and extend the 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.”
