Muon Space has more than 50 satellites already in development for customers.

US space-tech manufacturer Muon Space has raised $250m in a Series C round to meet the growing demand for satellites across industries.

The round was led by Eclipse Capital, with participation from Galvanize, Google, Salesforce Ventures, Wellington Management, I Squared Capital and Woven Capital. Existing backers included Radical Ventures, Congruent Ventures, Costanoa Ventures, Activate Capital, ACME Capital, ArcTern Ventures and Overlap Holdings.

The “heavily oversubscribed” round brings the 2021-founded satellite-maker’s total raise to more than $386m, and highlights investors’ hopes for the $1.8trn space-tech sector.

Satellite-building has become a lucrative business, as new-generation capabilities powered with AI open up opportunities across defence, surveillance, research and data processing.
