Muon Space raises $146M Series B to expand mission-optimized space systems

What does Muon Space do?

Muon Space is a provider of end-to-end space systems that designs, builds, and operates mission-optimized satellite constellations. Its proprietary technology stack, Halo, integrates advanced spacecraft platforms, payload integration, and a software-defined orchestration layer to deliver critical data and enable real-time compute in space.

How much did they raise?

The company raised $146M in a Series B round led by Congruent Ventures, with participation from Activate Capital, ACME Capital, Costanoa Ventures, Radical Ventures, and ArcTern Ventures.

What are their plans for the money?

Muon Space plans to use the funds to expand its operations and development efforts, further advancing its Halo platform and integrating in-house propulsion capabilities following its acquisition of Starlight Engines.

What have they achieved so far?

Muon Space has already enhanced its technology stack by acquiring Starlight Engines, a startup focused on developing commercially available solid propellant Hall-effect thruster systems, which strengthens its vertically integrated approach to space systems.
