Hangzhou Yuxing (Beijing Aerospace Yuxing Technology Co., Ltd.), founded in 2016 in Beijing, China, integrates R&D of commercial aerospace telemetry, tracking and control (TT&C) technology, spacecraft in-orbit operation services, serving global aerospace customers including satellite operators and rocket launch providers.

Founded in 2021 and headquartered in Mountain View, California, Muon Space builds and operates low Earth orbit satellite constellations end to end. Rather than selling spacecraft as hardware, it sells whole missions through what it calls Mission Foundry, bundling mission design, satellite buses, payloads, flight software, launch coordination and on-orbit operations into a single contract for defense, civil and commercial customers. Flying programs include FireSat, a wildfire-detection constellation built with Earth Fire Alliance and Google.org that TIME named one of the Best Inventions of 2025, and Vindlér 2.0, a radio-frequency data and analytics constellation for Sierra Nevada Corporation. As of August 2026 the company had launched 11 satellites across six launches with no mission failures, had more than 50 spacecraft in development and 13 manifested for launch within a year. Its San Jose manufacturing plant, opened in June 2026, is designed to reach 500 satellites per year by 2027. CEO and co-founder Jonny Dyer was previously chief engineer at Skybox Imaging.

HawkEye 360, founded in 2016 in Herndon, Virginia, provides satellite-based radio frequency data and analytics. The company serves defense, intelligence, and national security clients by detecting, geolocating, and analyzing RF signals worldwide.

Starfish Space, founded in Tukwila, Washington in 2019, develops satellite servicing vehicles capable of on-orbit docking and maneuvering spacecraft.

Observable Space, founded in 2025 in Los Angeles, manufactures laser communication ground stations, ground-based sensing systems, and in-orbit optical payloads for space object tracking and orbital data transmission.

Quantum Systems, founded in Germany in 2015, develops AI-powered drones for defense and commercial use, covering aerial intelligence and geospatial data collection.
