Top Defense Startups in 2026

The biggest waste in manufacturing today is not on the shop floor. It's in the meetings, emails, and data transfer that overwhelm knowledge processes (eg quality assurance, vendor management, engineering, R&D, and sales). That's because traditional enterprise tools split collaboration and processes into disparate systems, resulting in up to 85% of time and effort being wasted. Unifize solves this problem by bringing collaboration and process into one place. By creating a conversation for every process record, Unifize measurably reduces waste in knowledge processes by up to 95%.

AnySignal was developed to reimagine how RF capabilities are delivered for the most difficult tasks around the globe. offers complete solutions for modern aircraft, satellites, and national security that span communications, radar, navigation, and RF sensing. Current solutions are overpriced, unimaginative, and provide little end-to-end capability. To shift this paradigm, they are bringing the appropriate talent, procedures, and technologies together. They are developing communications systems for satellites, launchers, space stations, and aircraft. They provide full-stack connectivity solutions that include software modems, hardware for use in flight and on the ground, data management software, ground station integration software, and vehicle telemetry software.
