Dobbelgänger Oy: Advanced Decoy Technologies for European Defense Autonomy

In a quiet industrial corner of Finland, a small deep-tech company is reinventing one of warfare’s oldest tricks for the modern battlefield. Dobbelgänger Oy, an Oulu-based startup spun off from a leading Finnish research institute, is developing high-tech military decoys that look and “feel” real to enemy sensors. These aren’t mere inflatable dummies – they are lightweight, mobile devices with authentic radar and thermal signatures, engineered through printed electronics and advanced materials. The goal is simple yet ambitious: to mislead adversaries’ drones, satellites, and reconnaissance systems into chasing ghosts, thereby protecting real soldiers and equipment.

Founded in 2022 amid a rapidly changing security climate, Dobbelgänger has quickly drawn attention for its potential to bolster Europe’s defense autonomy. By allowing even smaller nations to simulate a larger military footprint, its technology adds a new layer to deterrence – one built on deception and technological ingenuity. This introduction explores the company’s origins and innovations, setting the stage for an in-depth analysis of how Dobbelgänger’s advanced decoys could strengthen European security in an era of strategic competition. Dobbelgänger Oy is a Finnish academic spin-off (deep-tech startup) developing advanced multispectral decoy systems for defense.

Its lightweight, deployable decoys mimic real military assets in visible, thermal, and radar spectra, aligning with European priorities in Sensor Technologies & Electronic Warfare and advanced materials. As a European-developed technology (born at VTT research centre), it contributes to EU strategic autonomy by substituting reliance on non-European suppliers for battlefield decoys. The company’s decoys enhance NATO interoperability in multi-domain operations by providing credible false targets for C4ISR and force protection. They directly support deterrence by denial – making an aggressor’s targeting costly and uncertain.

While still a startup (founded 2022, ~11 employees) with prototypes at TRL 6-7, Dobbelgänger has secured initial funding (e.g. FiBAN angels €100k) and engaged in EU innovation programs (Connect2Scale).
