Founded in 2023 by twin brothers Avner and Gabriel Bendheim, Tenna Systems converts existing signal emitters across aircraft, drones, satellites, ships, and mobile devices into a unified, real-time map of the electromagnetic spectrum. Its platform pinpoints radio-frequency interference within 50–200 meters and delivers actionable threat warnings without requiring additional hardware. The company’s product suite includes Arena for RF monitoring, Tracer for interference geolocation, and Halo embedded software for continuous RF resilience. Tenna is actively collaborating with the U.S. Army, U.S. Air Force, other federal defense agencies, and allied electronic-warfare units, where its technology has already been deployed in contested environments. With fresh capital, the firm intends to accelerate U.S. defense-market expansion and more than double headcount over the next year. Financially, Tenna has secured $13.5 million in seed funding to support these growth plans.
