Overview
- Tenna closed an oversubscribed $13.5 million seed round led by Costanoa with participation from Viola Ventures, Fresh Fund and 202 Ventures, and plans to more than double headcount within a year.
- The company’s platform takes data from existing aircraft, drones, satellites, ships and mobile devices to create a live map of the electromagnetic environment without adding new hardware.
- Tenna says its tools detect jamming, spoofing and other interference and can geolocate sources to roughly 50–200 meters to enable faster mitigation.
- The startup reports active work with the U.S. Army, U.S. Air Force and other federal agencies, along with operational deployments by allied electronic warfare and SIGINT units.
- The product suite comprises Arena for real-time monitoring, Tracer for precise geolocation and Halo for embedded RF resilience, and the firm was founded by twins Avner and Gabriel Bendheim after leading SIGINT and EW programs.
