Eclipse announced that Muon Space is ready to scale with a fresh $250M Series C funding round.

Eclipse invests in entrepreneurs building the next generation of companies in the physical economy — the industries that shape resilience, competitiveness, and security. We partner with founders tackling hard problems in sectors like manufacturing, supply chain/logistics, energy, transportation, and defense. These businesses operate in complex environments where technology, operations, and policy intersect — and where execution matters. We're Operators with Capital. Our team brings firsthand experience building factories, shipping hardware, scaling supply chains, and navigating the regulatory realities that shape the essential economy. We work closely with portfolio companies to sharpen strategy, pressure-test technology, recruit leaders, win early customers, and reach critical milestones. Beyond capital, Eclipse offers access to a broader ecosystem of operators, manufacturers, industry leaders, customers, and government stakeholders who help companies move faster and scale smarter. We back ambitious founders building enduring companies in the physical industries.
