HIMERA Raises $2.5M+ Seed to Scale Secure Military Communications

KYIV, Ukraine — 22 December 2025

HIMERA, a Ukrainian manufacturer of secure military communications systems, has raised more than $2.5 million in a seed round to scale production, expand network coverage and support deployments in Ukraine and abroad, the company and Ukrainian officials said.

The company builds handheld radios and related infrastructure designed to operate in electronic warfare conditions, where jamming and interception can disrupt command and control. The systems support voice and data transmission for units operating without fixed telecommunications infrastructure. The devices are designed for frontline use, including a battery life of up to four days.

HIMERA’s radios support mesh networking, allowing traffic to be relayed across multiple devices when there is no direct connection between endpoints. The company has said the systems use encrypted communications and are designed to reduce the probability of interception. The radios use frequency-hopping spread spectrum technology and encrypt traffic with 256-bit encryption.

HIMERA was founded in 2022. Misha Rudominski is a co-founder and chief executive officer of the company. The company’s engineering team is located in Kyiv and Tallinn.

Rudominski said the round was led by Green Flag Ventures, naming Justin Zeefe as the lead, with support from Dmitry Dubrovskyi of Nezlamni Fund, Yaroslava Dmytrasevych of United Angels Network and Vova Nesterenko of Freedom Fund VC, along with VYTACH, Big Defence, UA1 VC, Varangians, Bulava Capital and several angel investors.

“The final size of our seed round is just over $2.5 million. In total, since the company’s founding, we have raised over $3.2 million,” Rudominski said in an interview with Defender Media. The company previously received a $10,000 grant in 2023 and raised $525,000 from angel investors in 2024.

Ukrainian officials said HIMERA has moved from engineering and battlefield testing into a scaling phase, with systems already used by Ukrainian units. Mykhailo Fedorov, Ukraine’s First Deputy Prime Minister and Minister of Digital Transformation, said the funding would support faster solution development, broader coverage and more stable and secure communications for units operating daily in combat conditions.

The company is pursuing international expansion alongside domestic deployment. Fedorov said HIMERA is implementing contracts in Europe and the United States and entering new markets where resilient communications with a low probability of interception are critically important. In October, HIMERA announced it had completed a government order for the Ministry of Defense of a European NATO member country, without naming the country.
