Estonia is now a European launchpad for next-gen DefenceTech. This week, Ukrainian company Teletactica, which has an office and legal entity in Tallinn, raised $1.5M to expand its battlefield-tested communication systems designed to work in challenging military environments.
Positioning itself as an Estonian-Ukrainian company, Teletactica builds communication equipment specifically designed for military use in contested areas where traditional systems often fail. Their technology focuses on jamming-resistant communications that continue working even when enemies try to disrupt signals, encrypted data and voice connectivity for secure military coordination, operations in GPS-denied areas where satellite navigation isn’t available, and functionality in low-infrastructure environments where standard communication networks don’t exist.
Teletactica claims their systems deliver five times better price-to-performance compared to similar radios made in Europe and the United States.

Even when facing heavy electronic jamming attempts, their systems maintain packet loss rates of just 1-5%, ensuring critical communications get through. Most importantly, the technology is proven and already being used by Ukrainian forces.
The company’s hardware is currently deployed across Ukraine and is being adapted to meet NATO standards for broader international use. Here Estonia plays a major role. “The Estonian office is about a global perspective. We work here on products that meet NATO standards, have the potential for scalability and can be integrated into long-term rearmament programs of allies. This also gives access to European markets, funding programs, legal clarity,” says Eugene Zhebko, co-founder and CEO of Teletactica in his interview with DOU.UA.
The funding round was led by MITS Capital, an investment group based in both Kyiv and New York that focuses on Ukrainian defence innovations. US and Ukraine-based venture firm Green Flag Ventures also participated in the investment, bringing additional expertise and market connections to support the company’s growth.
