## About

Founded in 2021 by CEO Jonny Dyer, CTO Pascal Stang, Reuben Rohrschneider and Paul Day and headquartered in California, US, Muon Space Inc. focuses on developing satellite constellations for Earth intelligence. In August 2026, Muon Space, Inc. raised USD 250 million in series C funding led by Eclipse Ventures, with participation from other Galvanize Climate Solutions, GV, I Squared Capital, Overlap Holdings, Salesforce Ventures, Wellington Management, Woven Capital Management Company, ACME Capital, Activate Capital, ArcTern Ventures, Congruent Ventures, Costanoa Ventures, and Radical Ventures.

Muon Space specializes in the design, construction, and operation of low Earth orbit (LEO) satellite constellations, primarily for Earth intelligence missions. Their flagship product, Muon Halo, provides an integrated technology stack for optimizing satellite missions, enhancing constellation performance and ensuring faster time-to-orbit. The company employs a three-phase approach to satellite constellation development—design, build, and operate—facilitating reliable remote sensing capabilities from the start of deployment. Muon Space caters to a diverse clientele including government agencies like the United States Air Force (USAF) and the United States Space Force (USSF), as well as private companies such as Hydrosat, focusing on accurate weather data and geospatial intelligence in agriculture. Their products are marketed globally, especially in North America and Europe, where advanced Earth observation capabilities are increasingly necessary.

Muon Space generates revenue through contracts with government and private entities that require satellite constellation services. These transactions typically involve long-term agreements, with revenue models including subscription-based services for data access, project-based contracts for constellation development, and direct sales for specialized satellite services. Pricing structures are tailored to each client's specific needs, with products like Muon Halo central to these agreements, allowing the company to deliver customized solutions while fostering enduring client relationships across different sectors.

The company plans to utilize August 2026 funding to accelerate production of large-scale satellite constellations, expand its dual-use spacecraft platforms and support commercial, government and sovereign-customer demand.
