Teletactica, a Ukrainian DefenseTech company developing jamming-resistant communication systems for contested environments, has secured investment from MITS Capital and Green Flag Ventures. New funding will support the company’s scaling of next-gen tactical communications for frontline deployment and European expansion.

MITS Capital, an investment group based in Kyiv and New York and focused on Ukrainian defense innovation, led the $1.5 million round. Previously, Teletactica, MITS Acceleration Program alumni, successfully secured a pre-seed funding round.

“MITS Capital’s relationship with Teletactica is strategic, and the company has passed all the steps of our process to date, which began with the Acceleration Program. We’ve watched the company exceed every technical and operational milestone since,” said Perry Boyle, CEO & Founding Partner at MITS Capital. “We are proud to continue supporting Teletactica’s growth as they help define the future of battlefield communications.”

Green Flag Ventures, a leading U.S. and Ukraine based venture firm specializing in Ukrainian dual-use, AI, and cyber technologies, joined in the round.

“Teletactica exemplifies the kind of company we look for: strong team, powerful product, and the potential to dominate a large and critical market segment. The core team pivoted from the private sector and had the experience, skill, and knowledge to identify the frontline EW challenges and respond with unique, flexible, problem-solving solutions that are now being used by multiple units in Ukraine,” said Justin Zeefe, General Partner at Green Flag Ventures. Teletactica is expanding its product suite in Ukraine and already preparing to grow into Europe through sales and partnerships, he added.

Teletactica develops modular, secure communication hardware built for high electronic warfare (EW) and GPS-denied environments. Its flagship products include video and telemetry modems and antenna kits.

“We deliver battlefield-proven solutions where conventional systems fail”, said Eugene Zhebko, co-founder and CEO of Teletactica. All companies’ devices are built for low-latency data streams and offer five times better price-to-performance compared to radios manufactured in the EU and the US. Products maintain packet loss rates as low as 1% to 5%, even under heavy jamming.

“We offer resilience under jamming, real-time responsiveness, and large-scale deployability, at a cost that enables rapid mass adoption”, emphasized Anton Hetman, co-founder and CTO of Teletactica.

Teletactica’s hardware has a compact form factor and low power consumption, which makes it perfect for UAV drones, UGVs, and other small unmanned platforms. All solutions are designed for scalable production and support, keeping costs low enough to be deployed in numerous units, rather than being restricted to specialized and costly programs.

Teletactica’s hardware is already in use across Ukraine and is being adapted to NATO standards. “This is not theoretical tech; it’s saving equipment and people right now,” said Zhebko.

Teletactica is also a key resident of the Brave1 cluster, a platform created by the Government of Ukraine to promote collaboration between all stakeholders of the defense tech industry. MITS Capital and Green Flag Ventures acknowledge Brave1’s role in sharing expertise and creating a strong community within the Ukrainian defense tech industry.
