SSystellar
Systellar is a Barcelona-based deep-tech company that builds synapse™, an agentic, model-based systems engineering (MBSE) platform for hardware teams. Built on SysML v2, it brings system architecture, requirements, documentation and verification into one workspace, tracks how design changes affect requirements, and gives AI agents the full system context. The company started in space mission design with its orbitcompass™ tool, and several European satellite integrators use synapse™. Founded in 2024 and incubated at ESA BIC Barcelona, Systellar is a pre-seed company backed by Techstars, which took it into its London Spring 2026 accelerator; it also won a Santander X award in 2026 and was one of 15 finalists at the 2026 EU Startup Summit.
