On June 12, Muon Space announced the close of its oversubscribed $89.5 million Series B1 round, bringing total Series B funding to $146 million. The new capital includes $44.5 million in equity and $45 million in credit facilities, and follows the company’s initial Series B close in August 2024.
The B1 round was led by Congruent Ventures and included existing investors – Activate Capital, Acme Capital, Costanoa Ventures, and Radical Ventures. Muon also welcomed new investor ArcTern Ventures to the syndicate.
The new capital is fueling a scale-up of Muon’s operations – including expanded satellite production; vertical integration of key components such as propulsion and IR & RF instruments; deployment of Muon’s full-stack automated constellation operations platform; and the expansion of our global ground station network. The company has grown its team by 50% since December and surpassed $100 million in new contracts signed in 2024, including a landmark agreement with SNC to develop next-generation satellites supporting its Vindlér commercial RF sensing constellation.
“We’re focused on delivering mission-optimized satellite constellation systems to customers at unprecedented speed,” said Jonny Dyer, CEO of Muon Space. “High-performance constellations require the speed, cost, consistency, and performance of volume production – they can’t be built one satellite at a time. We are building the world’s first automated, high-mix, high-volume constellation manufacturing system. It’s always been about the mission – now we’re delivering it at scale.”
“Muon is building the high-performance scale solution the space industry has been missing,” said Joshua Posamentier, managing partner at Congruent Ventures. “By fulfilling mission requirements with a configurable, vertically integrated platform spanning hardware, software, and operations, they deliver a unique path to on-orbit capabilities – at a pace and price point that commercial, civil and national security customers urgently need.”
