Modern battlefields depend on uninterrupted wireless communication, yet today’s skies, seas, and operational theatres are increasingly threatened by jamming, spoofing, and unpredictable interference. Into this high-stakes challenge steps Tenna Systems, which has now raised $13.5 million in oversubscribed seed funding to accelerate a new era of software-driven spectrum resilience across defence, aerospace, and mobility sectors.
The round was led by Costanoa, with participation from Viola Ventures, Fresh Fund, 202 Ventures, and existing backers. With this funding, Tenna plans to more than double its headcount over the next year as it deepens the U.S. market expansion and scales deployments globally.
As disclosed to TFN, Tenna Systems stated that it plans to “execute on a growing amount of defence and commercial contracts and partnerships, including for the US Army, US Air Force, and Israel Ministry of Defence.”
A unified view of an invisible battlespace
Billions of dollars in defence and autonomous assets rely on clean, uninterrupted spectrum access. Yet the rise of unmanned systems, satellite networks, and dense signal environments has made the electromagnetic domain harder to monitor than ever.
Tenna’s breakthrough lies in transforming existing aircraft, drones, satellites, ships, and even mobile devices into live sensors. Rather than layering costly new hardware onto defence fleets, the company’s software stitches these sources together into a real-time spectrum map, identifying interference with pinpoint accuracy, often within 50 to 200 metres.
This approach enables operators to see emerging threats, turning moments of uncertainty into rapid, informed action.
Modern spectrum resilience
Tenna was founded in 2023 by twin brothers Avner and Gabriel Bendheim, who spent decades building and leading sophisticated SIGINT and electronic warfare programs. Their experience revealed a widening gap wherein traditional, hardware-heavy systems were no longer suited to fast-moving, wireless-first conflict environments.
This insight shaped Tenna’s mission to deliver a scalable, software-first platform that thrives in congested spectrum conditions. The technology has already proven its reliability in operational deployments with U.S.-allied forces in active conflict zones, where clean connectivity can be the difference between mission success and mission failure.
Tenna is already working closely with the U.S. Army, U.S. Air Force, and multiple federal defence agencies to strengthen the spectrum resilience of wireless systems. The company is also supporting prime contractors and SIGINT units within allied forces, further embedding its technology in mission-critical operations worldwide.
Products built for real-time threat detection
Tenna’s product suite covers the full spectrum of connectivity needs:
- Arena – Offers real-time monitoring to detect signal gaps and interference across any operational environment.
- Tracer – Pinpoints the precise location of interference sources, enabling rapid mitigation and countermeasures.
- Halo – Embedded resilience “armour” ensuring continuity for wireless-dependent systems, even when under active attack.
Together, these tools help defence teams understand not only whether interference is occurring, but also where, why, and how to respond.
How about diversity?
Regarding diversity, the company stated, “Tenna Systems is a small, mission-driven team with diversity across age, gender, military service, and employment background. The team includes women in technical and research roles, senior experts over 70 alongside early-career contributors, a strong representation of veterans and active reservists from multiple armed forces units, and a mix of full-time staff and part-time students supporting early-career talent development.”
Building the world’s first dynamic spectrum map
Formerly known as Tip & Cue Inc., Tenna is now positioned as a leading force in modern spectrum intelligence. Its vision is bold yet clear to build the world’s first dynamic, unified map of the electromagnetic spectrum, ensuring seamless wireless connectivity across all domains.
As wireless systems increasingly define the future of defence and mobility, Tenna’s hardware-free, software-first approach may be exactly what modern electronic warfare requires: speed, clarity, and resilience in a domain long clouded by uncertainty.
“Much like AccuWeather but for electronic warfare, our software transforms the blizzard of sensor data into a real-time map of Radio Frequency (RF) domains. This gives our partners a ground truth in navigating the electromagnetic spectrum,” said Avner Bendheim, co-founder and CEO at Tenna. “Agility is everything in the evolving world of the electromagnetic spectrum. While traditional solutions demand costly infrastructure rollouts and custom sensors, we provide a hardware-free solution that is as essential as any other mission-critical tool.”
“Tenna’s founding team brings a rare mix of operational, technical, and commercial expertise,” said Greg Sands, Founder and Managing Partner at Costanoa. “We believe Tenna is advancing a new era of spectrum intelligence to protect connectivity across all domains. It has the power to transform how defence partners secure wireless systems, ensuring readiness and resilience on a global scale.”
