Photoneo
Photoneo is a Bratislava-based robotics and machine-vision company focused on giving industrial automation systems reliable 3D perception in difficult physical environments. Its technology is built for tasks where standard 2D imaging or lower-quality depth sensing breaks down, such as picking mixed objects from bins, sorting items on fast-moving lines, or guiding industrial robots through high-precision work.

In ecosystem terms, it is a strong example of Slovak deep-tech with direct relevance to fulfillment, production, and warehouse efficiency across Europe.
