About us
Drone technology built for real-world missions
Leave a Mark Intelligence develops modular drones for surveillance, field observation and coastline monitoring – designed to be easy to operate, maintain and configure.
Who we are
Experience from technology, IT and security
Our team combines many years of experience in technology, product development, IT and security. We use that experience to build drones that solve practical problems in the field – without unnecessary complexity.
By combining standard components with 3D-printed modules, we keep our drones affordable and accessible – for smaller organisations as well as large enterprises.

Our approach
Modular by design
Every drone is built to be adapted. Whether you need long-range zoom, night vision, infrared cameras or specialised motors, we configure the drone to your specific requirements.
Modular design
Built from modules for easy maintenance and fast reconfiguration to suit each mission.
Cost-effective
Standard components and 3D-printed parts keep prices down – from EUR 15,000 to EUR 250,000 depending on configuration.
Advanced technology
State-of-the-art autopilot, GPS and optional long-range radar for safe and reliable operation.
