Deftak

Deftak is a Ukrainian-Estonian startup, based in Kyiv, that builds computer-vision-guided munition kits which mount on standard drones — including reconnaissance quadcopters — to turn them into precision strike platforms. The munition carries onboard electronics, a camera and a warhead; using computer vision it locks onto a designated target point and adjusts its trajectory in flight, hitting accurately without a satellite signal and under electronic-warfare jamming. It can be released from a drone hovering at altitude, then guide itself the rest of the way down. The company says the approach is up to roughly ten times cheaper than conventional guided munitions, that the kit has already been through combat testing, and that fixed-wing and laser-guided variants are in development.

The project traces back to a Ukrainian drone hackathon in 2022, where the founding team’s concept won, before being formalised as a company. In May 2025 Deftak raised about €600,000 from Darkstar, a European defence-investment fund, to scale production, and it has said it is pursuing codification with Ukraine’s Ministry of Defence — the formal step that lets a system be procured for the armed forces. In 2026 the firm was named among Ukrainian defence startups backed by the Angel One Fund, and it works as part of the country’s defence-tech ecosystem alongside the state cluster Brave1 .

Deftak occupies the same vision-guided strike niche as several other Ukrainian developers it can be grouped with — The Fourth Law , Dwarf Engineering and Twist Robotics — though where some of those firms sell autonomy software that runs on a drone’s own flight controller, Deftak’s product is a self-contained guided munition. As with most young firms in this segment, its performance and deployment claims trace largely to the company itself rather than to independent testing.
