Tianxu AI

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.
