ReOrbit

ReOrbit, founded in 2019 and headquartered in Helsinki, Finland, builds software-defined satellite systems for secure communications, intelligence, and national security customers. The company manufactures sovereign satellites and connected systems, positioning its work at the intersection of defence, space, and secure communications - domains where who controls the spacecraft, the ground segment, and the ability to change them after launch matters as much as the hardware itself.

Its stated focus on spacecraft reconfigurability and autonomy is the throughline: software-driven approaches layered onto traditional space engineering, so that systems can be updated and adapted rather than frozen at launch. Product lines include Silta, a sovereign communications satellite system; OrbitCloud, a defence connectivity platform; systems designed to support direct-to-device satellite communications; and systems designed to support orbital intelligence capabilities. Technical domains span spacecraft engineering, satellite communications, and connected systems more broadly.

For security-minded engineers, the operating model is worth noting. ReOrbit describes a flat structure with minimal unnecessary hierarchy, multidisciplinary collaboration across offices and disciplines - engineers, operators, designers, and business specialists working together - and an emphasis on knowledge transfer so that customers can operate systems independently over the long term. Stated cultural signals include open communication, evidence-based decision-making, trust, humility, and curiosity.
