Clausal. Helsinki, Finland. Onboard autonomy for GNSS-denied operations. Satellite navigation can no longer be assumed. Jamming and spoofing are routine, and uncrewed systems increasingly have to navigate, hold position and understand what they are looking at without a GNSS fix and without a reliable link home. Clausal builds the onboard autonomy that keeps working when that happens. Our runtime handles absolute positioning, navigation and object detection entirely onboard, using multi-modal sensing rather than satellite signals. Getting that to work in a lab is one thing. Getting it inside the size, weight and power budget of a small uncrewed platform, robust enough for real conditions, is the actual engineering problem. That constraint shapes how we build. We train and simulate at scale in Europe, then compress the result until it fits the target hardware. Models, weights and customer data stay in Europe. What we work on: machine learning and computer vision for positioning and detection. Embedded software and model compression for constrained hardware. Hardware and sensor integration. Simulation infrastructure. Systems engineering and go-to-market. Who we are: a 25 head strong team in Helsinki. Our founder and CEO, Tatu Ylönen, invented the SSH protocol and built SSH Communications Security into a public company. The rest of the team comes from European space, telecoms and AI companies, with patents across AI, cybersecurity and aerospace. We work in defence and dual-use. Our technology is developed for military and security customers as well as civilian uncrewed systems, and we are open about that. If it is not for you, better to know now. Why join: deep tech with a short path to the field. Problems that are genuinely unsolved. A team small enough that your work is visible in the product, and customers who tell you quickly whether it works. Finland based. clausal.com
