Summary
Muon Space designs, builds, launches, and operates mission-specific satellite constellations end-to-end — backed by a 100% mission success rate across and a customer base spanning Google’s FireSat wildfire detection constellation to the U.S. Space Force. Salesforce Ventures is proud to invest in Muon Space’s Series C.

The Opportunity
Satellite constellations have become essential infrastructure. They power wildfire detection, weather forecasting, maritime monitoring, and dozens of other mission-critical use cases across government and the private sector. But the supply side hasn’t kept pace with this demand. Legacy vendors dominate large government and commercial programs, yet their cost-plus contracting and decade-long development cycles make it difficult for them to deliver with the speed and flexibility today’s burgeoning space economy demands.
The newer market entrants have largely evolved along two tracks: hardware providers that leave integration to the customer, and single-mission operators with deep but narrow stacks. What has remained harder to find is a single partner who can design, build, launch, and operate a mission-specific constellation end-to-end.
The Solution
Muon Space is filling the demand for high-performance satellite constellations with its Mission Foundry. Mission Foundry is a vertically-integrated platform spanning mission design and simulation, modular spacecraft platforms, in-house payloads (optical, infrared, and radio frequency), tight integration of 3P payloads, constellation production, and managed orbital services, all built on the company’s unified flight, ground, and data infrastructure. Rather than subcontracting pieces of the stack, Muon designs and builds the spacecraft, payload, propulsion, and software, letting it move faster and more flexibly than legacy vendors while offering a more complete solution than newer providers.
Muon’s approach is resonating with a customer base that spans both commercial and national security missions. Google and the Earth Fire Alliance partnered with Muon to build FireSat, the world’s first dedicated wildfire detection constellation. Sierra Nevada Corporation turned to Muon for Vindlér 2.0, a constellation for commercial RF data collection and analytics services. On the government side, the U.S. Space Force selected Muon for its SBEM Phase III program, with the goal of replacing a 40-year-old satellite architecture.
Underpinning Muon’s commercial and government appeal is a flight record that’s rare in the industry: Muon has launched 11 satellites to date with a 100% mission success rate, at a time when roughly 40% of small satellites fail to meet their mission.
Why We’re Backing Muon Space
We’re excited about Muon because the company sits squarely at the intersection of two qualities we look for in space infrastructure investments: deep vertical integration and a team with a track record of success in the industry. Muon’s ownership of the full stack — bus, payload, propulsion, software, and operations — gives it a structural advantage over point-solution competitors, and its execution record shows that advantage is translating into real customer wins across both commercial and defense markets.
That execution is attributable to the caliber of Muon’s founding team. CEO Jonny Dyer and CTO Pascal Stang met at Skybox Imaging, one of the first venture-backed satellite companies, where Jonny rose from first employee to CTO and Pascal served as a satellite systems architect. The duo helped build and launch 21 satellites before Google acquired Skybox. Both went on to Google and later Lyft’s autonomous vehicle unit before co-founding Muon in 2021. They’re joined by co-founders Reuben Rohrschneider (15 years at Ball Aerospace) and Paul Day (Terra Bella/Google, Apple, and Loft Orbital), rounding out a leadership team with decades of combined experience across nearly every major player in the industry.
What’s Ahead
We see satellite constellations becoming as foundational to modern infrastructure as data centers or cloud compute — supporting everything from climate monitoring to national defense to global connectivity. And we believe the winners will be the platforms that can own the full mission lifecycle rather than a single slice of it. Muon’s combination of vertical integration, flight heritage, and dual-use traction positions it to be one of those winners as the space economy scales.
We’re looking forward to supporting the Muon team with access to the Salesforce Ventures network and our relationships across the enterprise and government landscape as they continue to scale towards liftoff.
