Muon Space has closed a $250 million Series C round, bringing total equity funding past $386 million.
Eclipse led the financing, the satellite company said Thursday. Google, Salesforce Ventures, Wellington Management, Galvanize, I Squared Capital and Woven Capital joined as new investors, alongside returning backers, including Radical Ventures, Congruent Ventures, Costanoa Ventures, Activate Capital, ACME Capital, ArcTern Ventures and Overlap Holdings.
Muon said the round was oversubscribed.
What Will Muon Space Do With the Series C Proceeds?
The production of large-scale constellations and the expansion of the company’s dual-use spacecraft platforms are the stated priorities. Muon also pointed to advanced payloads, on-orbit AI compute and high-bandwidth satellite connectivity developed with SpaceX Starlink.
Jonny Dyer, CEO of Muon Space, said the company built its model to let customers field complete constellation systems in months rather than years.
Lior Susan, founder and CEO of Eclipse, said Muon has combined mission design, manufacturing, launch and operations into one platform.
What Defense and Intelligence Work Does Muon Space Hold?
Space Systems Command awarded Muon a $44.6 million Small Business Innovation Research Phase III other transaction agreement in October to build a three-satellite prototype demonstrating space-based environmental monitoring for the Department of War. The Joint Requirements Oversight Council identified cloud characterization and theater weather imagery as the mission’s top priorities.
The National Reconnaissance Office awarded the company a Stage II contract in May 2025 under its Strategic Commercial Enhancements Broad Agency Announcement Framework, covering multispectral electro-optical and infrared data and demonstration work.
Muon was among five companies picked in December 2023 to supply commercial electro-optical capabilities under the NRO’s Electro-Optical Commercial Layer program.
How Much Manufacturing Capacity Does Muon Space Have?
An advanced manufacturing plant that recently opened in San Jose, California, is designed to produce up to 500 satellites per year by 2027, a tenfold increase over its previous capacity.
More than 50 satellites are in development for customers, with 13 manifested for launch over the coming year.
Seven satellites went up in the first half of 2026, bringing the company to 11 deployed over six launches. Muon reported a 100 percent mission success rate.
Two customer constellations enter operation this year: Vindlér 2.0, an RF data and analytics system for SNC, and FireSat, a wildfire-monitoring constellation built with Earth Fire Alliance and Google.
