Impulse Space raises $500M Series D to scale “space mobility” for satellite-ferrying orbital transfer vehicles

Impulse Space has closed a $500 million Series D led by 137 Ventures and Banner VC, valuing the company at $4.26 billion. The funding is earmarked for building out production of ultra-mobile spacecraft designed to ferry satellites and other payloads in orbit, and for expanding the broader space-mobility infrastructure stack.

Briefing

What Hype is tracking

The $500M Series D at a $4.26B valuation underscores that “infrastructure” plays in orbital logistics are attracting scaled institutional capital, echoing earlier reporting on Europe’s need for finance to reach that growth tier (European space startups press for “infrastructure” financing).
Impulse Space’s stated focus on production expansion for orbital transfer “mobility” platforms adds to the momentum in on-orbit servicing and maneuverable spacecraft business models that are moving from demos toward scalable fleets (Starfish Space closes ~$110M Series B).
The raise aligns with the broader investor narrative that 2026 is a step-change moment for space infrastructure demand and institutional participation, reinforcing how quickly funding is flowing to LEO operational layers beyond launch (Seraphim: 2026 Is “Pivotal”).
