U.S.-Ukrainian startup Sky-Spy has raised USD 1.6 million to develop an autonomous signals intelligence (SIGINT) platform designed for the current war in Ukraine and future conflicts. The company is building a system that can detect and analyse enemy emissions across the radio spectrum, integrate with unmanned platforms and give commanders a near real time picture of the electronic battlefield.
From manual spectrum monitoring to autonomous SIGINT
In many units, spectrum monitoring still relies on scattered hardware and highly specialised operators. Sky-Spy is trying to turn SIGINT into a scalable product: modular sensors on tripods, vehicles or drones send data into a software platform that classifies signals, maps emitters and flags threats such as jammers, UAV control links or command posts.
The goal is to reduce the dependence on scarce experts and to give frontline units actionable information in a format they can understand: icons on a digital map, risk scores, recommended manoeuvres for drones or ground assets. Automation and pre set workflows are key to making the product usable at scale, not just in elite units.
Product architecture and monetisation
According to the company, the platform is being built as a combination of hardware kits and a software layer that can be deployed on secure servers or field laptops. Sensors can be mounted on small UAVs, ground robots, vehicles or fixed positions near the front. The software aggregates data, correlates it with other sources and helps operators prioritise targets and routes.
- hardware modules for RF sensing and direction finding;
- autonomous or semi autonomous drone missions tasked with collecting SIGINT;
- a software platform that fuses, visualises and shares signal intelligence;
- service and upgrade contracts tied to new threat profiles and waveforms.
From a business perspective, this opens up revenue streams from Ukrainian defence customers today and from allied markets later, once export licences and compliance frameworks are in place.
What the deal signals for defence-tech investors
The Sky-Spy round underlines how Ukraine has become a live testbed for electronic warfare and counter EW technologies. Investors are looking for teams that can solve very specific frontline problems — locating enemy jammers, protecting friendly drones, mapping command nodes — and then convert those solutions into repeatable products.
For defence-tech investors, the key questions will be how interoperable Sky-Spy becomes with existing NATO systems, how quickly the team can industrialise hardware production in Ukraine or nearby EU countries, and whether the company can maintain a technological edge as adversaries change their tactics in the spectrum. If the platform scales, it could join the emerging group of Ukrainian-origin companies shaping the next generation of defence electronics.
