Ukrainian defense company Vigilant Works attracted investment from the American venture fund Backswing Ventures.
Vigilant Works is developing autonomous counter-drone systems, high-speed interceptor drones, and radar technologies. The startup previously received funding from the Ukrainian Angel One Fund.
In parallel, the company is developing cooperation with the Lithuanian manufacturer Sky Motors Lab, with which it plans to create specialized electric motors for high-speed interceptor drones.
More about the Backswing Ventures investment
The amount of the investment and other financial terms are not disclosed. The Ukrainian company plans to direct the raised capital toward the development of autonomous guidance technologies, next-generation radar systems, and preparation for scaling production and entering NATO country markets.
Vigilant Works has already concluded its first commercial agreements outside Ukraine. However, the company is not yet disclosing the names of the clients, the countries of supply, the volumes of the contracts, or the financial terms.
Backswing Ventures — an American venture fund founded in 2020 that specializes in investing in defense and dual-use technology companies.
Among those in which the fund invested are companies working on autonomous systems, artificial intelligence, missile technologies, cybersecurity, and threat detection means.
Previous investments of Vigilant Works
In July 2026, the Ukrainian venture fund Angel One announced an investment in a company. For the fund, this was the fourth deal in the defense sector in 2026.
The parties did not disclose the exact amount of the deal at the time. However, the typical investment size of Angel One ranges from $50,000 to $200,000. Angel One reported additional grant support for the development of Vigilant Works — Algiz-2.
Vigilant Works developments
Vigilant Works is creating an integrated ecosystem for countering unmanned aerial vehicles, which should unite three main components: interceptors, autonomous control technologies, and radar detection means.
The company's first development was the Algiz-1 platform, which has already undergone combat testing. The team is currently working on Algiz-2 — a high-speed interceptor capable of reaching speeds of over 600 km/h. The platform has already moved to the active phase of combat testing.
Co-founder of Vigilant Works Daniel Korohodskyi believes that the future of countering drones depends on the integration of the entire interception cycle. In his opinion, the radar, autonomous control, and high-speed platform should be developed as a single system, rather than as separate components.
Production capacities in the EU
Recall that Vigilant Works entered into a partnership with the Lithuanian company Sky Motors Lab.
Vigilant Works creates autonomous interceptor drones that can fly at speeds over 600 km/h. Such high-speed flights require engines capable of withstanding high temperatures and significant loads.
It is these that Lithuanian Sky Motors Lab intends to develop. The company will design, create, and test special brushless electric motors adapted to operate at such speeds.
