Investment thesis
SpaceFund is an early-stage venture capital firm dedicated exclusively to the emerging commercial space economy. It invests in visionary yet practical startups targeting multi-billion dollar markets, deliberately avoiding traditional aerospace while considering space transportation, critical components, and the supply chains needed for space operations and exploration. The firm combines dedicated sector focus, experienced operators and investors, and ongoing proprietary market research to identify startups likely to matter in the rapidly expanding new-space ecosystem. SpaceFund works actively with portfolio companies from inception toward durable scale and successful exits, and publishes research on market size, financing, and exit trends to support investors and founders across the industry.
