Tenna Systems, a firm specialising in software-based spectrum resilience, has secured $13.5 million in an oversubscribed seed funding round to combat wireless communication threats like jamming and spoofing across defence, aerospace, and mobility sectors, as published by Tech Funding News.
The investment was led by Costanoa, with participation from Viola Ventures, Fresh Fund, 202 Ventures, and existing backers. Tenna stated it plans to more than double its headcount over the next year to deepen its U.S. market expansion and scale global deployments.
According to the company, it aims to execute on a growing number of defence and commercial contracts and partnerships, including those with the US Army, US Air Force, and Israel Ministry of Defence.
Founded in 2023 by twin brothers Avner and Gabriel Bendheim, who have decades of experience in signals intelligence and electronic warfare programmes, Tenna was created to address a gap left by traditional hardware-heavy systems in fast-moving conflict environments.
Its technology transforms existing aircraft, drones, satellites, ships, and mobile devices into live sensors, stitching them together into a real-time spectrum map. This software-driven approach identifies interference with pinpoint accuracy, often within 50 to 200 metres, providing operators with a clear view of emerging threats.
The system has proven reliable in operational deployments with U.S.-allied forces in active conflict zones, where uninterrupted connectivity is critical. Tenna is already working with the U.S. Army, U.S. Air Force, and multiple federal defence agencies to strengthen spectrum resilience, and supports prime contractors and signals intelligence units within allied forces worldwide.
Tenna’s product suite includes Arena for real-time monitoring of signal gaps and interference, Tracer for pinpointing the location of interference sources, and Halo for embedded resilience to ensure continuity during attacks.
The company described itself as a small, mission-driven team with diversity across age, gender, military service, and employment background, including women in technical and research roles, veterans, and a mix of full-time staff and part-time students.
Formerly known as Tip & Cue Inc., Tenna’s vision is to build the world’s first dynamic, unified map of the electromagnetic spectrum. Co-founder and CEO Avner Bendheim said the software acts like “AccuWeather but for electronic warfare,” transforming sensor data into a real-time map of radio frequency domains to provide ground truth in navigating the spectrum.
Greg Sands, Founder and Managing Partner at Costanoa, said Tenna’s founding team brings a rare mix of operational, technical, and commercial expertise, advancing a new era of spectrum intelligence to protect connectivity across all domains.
