# SpaceTech Series A+ funding gap is the structural bottleneck because specialized VCs concentrate at seed while generalists lack domain expertise for hardware companies

Analysis of 65 SpaceTech venture deals exceeding $5M in 2024 reveals a structural funding gap: specialized space VCs (Space Capital, Seraphim, Type One) concentrate at seed and early stages, while Series A+ rounds must attract generalist VCs (a16z, Founders Fund, Tiger Global) or corporate investors (Airbus Ventures, Toyota Ventures, Lockheed Martin Ventures) who bring different evaluation frameworks and expectations.

This creates a valley of death for hardware-intensive space companies. A satellite manufacturer or propulsion startup that successfully demonstrates technology at seed stage faces a capital gap: the specialized VCs who understand the technology don't write $50M+ checks, and the generalist VCs who do write large checks apply software-like metrics (ARR growth, unit economics) that poorly fit hardware development timelines.

The 2024 data shows capital concentration at extremes: large rounds go to category leaders (Firefly $175M, Astranis $200M, The Exploration Company €150M, ICEYE $158M) while mid-stage companies scramble. The emergence of debt financing alongside equity (HawkEye 360 $40M debt, Slingshot $30M debt, ABL $20M debt) signals that later-stage companies are finding creative structures to bridge the gap.

The repeat backer pattern is telling: Founders Fund, Lux Capital, Khosla Ventures, and Sequoia appear across multiple space deals, suggesting a small club of generalist VCs has built space expertise — but the club is too small for the sector's capital needs.

## Challenges

The gap may be self-correcting as the sector matures. Axiom Space raised $350M in February 2026. CesiumAstro raised $270M Series C. These demonstrate that institutional capital is flowing to later stages. The question is whether this is broadening (more funds gaining space expertise) or concentrating (the same small club writing bigger checks). Geographic diversification (Gilmour $146M in Australia, Interstellar Technologies $94M in Japan) also suggests the gap is less severe outside the US.

Relevant Notes:
- [[the space economy reached 613 billion in 2024 and is converging on 1 trillion by 2032 making it a major global industry not a speculative frontier]] — $613B economy with insufficient growth-stage capital
- [[value in industry transitions accrues to bottleneck positions in the emerging architecture not to pioneers or to the largest incumbents]] — the VCs who build space domain expertise at growth stage may hold bottleneck positions in capital allocation
- [[Rocket Lab pivot to space systems reveals that vertical component integration may be more defensible than launch in the emerging space economy]] — Rocket Lab's $38.6B cap shows the market rewards the systems play, but achieving that requires navigating the Series A+ gap
