ReOrbit
Helsinki-based ReOrbit builds software-defined satellite buses and a sovereign satellite OS stack targeting defense, national-security, and critical-infrastructure operators.
Background
ReOrbit was founded in Helsinki in 2019 by Sethu Saveda Suvanam and has grown into one of Finland's most-capitalized space startups.
The company's pitch centers on displacing purpose-built, single-mission satellite hardware with a software-reconfigurable platform that lets operators update mission logic on orbit.
Its product line consists of three named systems: Gluon, a software-defined small satellite bus developed with SatixFy for the onboard processor; SILTA, a software-defined GEO communications platform; and UKKO, an Earth-observation and ISR platform.
Across all three, ReOrbit provides integrated satellite hardware, payload interfaces, and a sovereign operating-system layer that keeps command-and-control inside the customer's national infrastructure rather than on a shared commercial cloud.
ReOrbit goes to market primarily through direct government and institutional channels, positioning Gluon, SILTA, and UKKO as turn-key sovereign-communications and ISR solutions for NATO-aligned governments.
LinkedIn headcount is listed at 51–200 employees, making the company roughly mid-stage in staffing terms.
