Enpulsion is named in 31 signals and Orbion Space Technology in 4.
Enpulsion makes FEEP electric propulsion systems using indium propellant, including Nano R³, Micro R³ and Nexus, for small satellites.
Darker bar: ahead of the other company on that measure.
Enpulsion is an Austrian electric-propulsion maker and the deployment-count leader of the field, with 320+ FEEP (field-emission) systems operating in orbit and 500+ cumulative years of flight heritage (more units flying than any competitor in the micro/nano class), across a modular ladder from IFM Nano up to the new 500kg-class Nexus (August 2026). It raised a EUR 22.5M growth round in March 2026 (Nordwind-led) to move upmarket and into the US as sovereignty demand rises, with every-unit acceptance testing as its reliability claim. Revenue is estimated at 10-100m class.

Orbion Space Technology manufactures Hall-effect electric propulsion systems for spacecraft, including higher-thrust propulsion integrated into York Space Systems satellite platforms.
Darker bar: ahead of the other company on that measure.
Orbion Space Technology (Houghton, MI) makes the Aurora integrated Hall-effect propulsion system (thruster, power-processing unit, and propellant management; krypton life-qualified, >60 mN/kW), delivering 33 units to York Space Systems for a US military constellation and flying in the SDA PWSA. It was acquired by York Space Systems in March 2026 (terms undisclosed) as a vertical-integration move, and continues serving third parties as a wholly-owned subsidiary. Production rate and the third-party order book after the acquisition are the open questions.
