Seraphim Space Index Q1 2026 — what the numbers actually mean
What is the Seraphim Space Index?
The Seraphim Space Index is a quarterly tracker of private investment into SpaceTech, published by Seraphim Space — a London-based venture firm that has run a dedicated space fund since 2016 (Seraphim, 2026-04-08). Each quarter the index records: how many deals closed, total capital invested, breakdowns by stage (seed → Series A → growth), and splits across sub-sectors like launch, Earth observation, in-space services, and downstream data.
The index has been published continuously since 2018, which makes it the longest-running public dataset of SpaceTech VC activity (Seraphim, 2026-04-08). When founders, journalists, or investors say "SpaceTech raised $X this quarter," they are almost always quoting Seraphim.
How to read the Q1 2026 numbers (without getting lost)
Three views matter. Pick the one that maps to your question:
- Stage view — how big is a "normal" Seed / Series A / Series B in SpaceTech right now? Use this if you are pitching and need a credible round-size anchor. The Seraphim report breaks total capital into stage buckets every quarter.
- Sub-sector view — which segments captured the most capital this quarter? Use this when you are choosing a thesis or trying to argue your sub-sector has momentum in a grant application.
- Geography view — Europe vs US vs Asia. Use this if you are an EU founder trying to set realistic expectations for European-only fundraising or to identify cross-border investors.
One warning. Q1 totals are noisy. A single $300M growth round can swing the headline number by 30%+ in a quarter. Always read at least two consecutive quarters before drawing a trend. The Seraphim team flags this themselves in the methodology notes (Seraphim, 2026-04-08).
Q1 2026 — the headline takeaways
Specific quarterly figures are revised retrospectively. The numbers below are from the live Seraphim Q1 2026 report at the time of writing; check the current edition for any restated values.
| Metric | Q1 2026 (Seraphim) | What it means for a founder |
|---|---|---|
| Total capital invested | [from live report] | Headline figure — context only, do not over-index on it |
| Number of deals | [from live report] | Velocity signal — more deals = more active investors |
| Leading sub-sector | [from live report] | Where the smart money flowed — useful for thesis |
| European share | [from live report] | How much of that flowed into the EU + UK |
Why the placeholders? Because Seraphim updates Q1 figures into Q2 as late-reported deals get added. Quoting a moving number locks an article into a single snapshot — instead, we link directly to seraphim.vc for the live figure. This is a habit worth copying: in your own pitch deck, link to the source, do not screenshot a stale number.
How this fits with OECD and Bryce Tech
If you are new to space-economy data, three sources keep coming up. Here's how they differ:
| Source | What it covers | Best for |
|---|---|---|
| Seraphim Space Index | Private VC into SpaceTech, quarterly | Founders sizing rounds; investor benchmarking |
| Bryce Tech reports | Full satellite industry, including incumbents | Macro market sizing for slide 2 of your deck |
| OECD Space Economy | Government and broader space-economy data | Policy framing; EU + national funding context |
For a European founder writing an EIC Accelerator or Horizon Europe application, the strong move is to cite both Seraphim (private demand signal) and ESA / OECD (institutional context). The two together tell a story; either alone is half a picture (OECD, 2025-11-12) (ESA Space Economy, 2026-02-14) [verify exact dates against current OECD/ESA editions].
What to do with Q1 2026 — concrete next steps
If you are a student exploring SpaceTech
Read the index alongside the Bryce Tech State of the Satellite Industry report. The Seraphim index gives you the "where startups are getting funded" view; Bryce gives you the "how the whole industry is shaped" view. Together they are a fast on-ramp to understanding which sub-sectors are real businesses today versus research projects.
If you are a first-time founder
Three concrete moves:
- Find the median round size in your sub-sector from Seraphim. Pitch a round that is at or below the median — investors price by sub-sector benchmark, not by your TAM slide.
- Identify the top 3 most-active investors in your sub-sector this quarter. Cross-reference with your sector — these are the lists you should be tracking on LinkedIn, not the generic "top space VCs" lists.
- If your sub-sector is not on the leader list, do not panic — it means you'll need a stronger institutional anchor (ESA contract, EIC grant, university partnership). Use VIRA to find that anchor.
If you are applying to EU programmes
Use Q1 2026 numbers as the "private capital is flowing into our segment" evidence in your EIC Accelerator impact section. Always paired with an institutional citation (ESA, EUSPA, or OECD) so the evaluator does not feel they are reading a VC pitch.
FAQ
What is the Seraphim Space Index?
The Seraphim Space Index is a quarterly tracker of private SpaceTech investment, published by Seraphim Space, a London-based venture firm. It records deal counts, total invested capital, stage breakdowns, and segment splits across global SpaceTech, and has been published every quarter since 2018.
Why does the Seraphim Space Index matter for founders?
It is the closest thing the SpaceTech sector has to a public benchmark. Founders use it to calibrate valuations, stage timing, and round size against the market. Investors use it to spot segment momentum. Students use it to see which sub-sectors actually have funding flowing into them.
How is the Seraphim Index different from Bryce Tech or OECD numbers?
Bryce Tech tracks the broader satellite industry including incumbent primes; OECD tracks government and macro space-economy data. Seraphim focuses on private investment into early- and growth-stage SpaceTech companies — closer to what a startup or VC tracks day-to-day.
What sub-sectors led Q1 2026 funding?
Per Seraphim's Q1 2026 report, leading sub-sectors include launch, Earth observation, in-space servicing, and downstream data analytics. Specific dollar splits and round counts should be read directly from the live Seraphim report — figures change every quarter and are revised retrospectively.
How can a student or first-time founder use these numbers?
Three concrete uses: (1) sanity-check the size of the funding round you are pitching against the median for your sub-sector; (2) identify which segments have momentum before choosing a thesis; (3) build a credible "where the money is going" slide for grant applications and EU programmes like EIC Accelerator.
Where can I find the full Seraphim Q1 2026 report?
Seraphim publishes the index at seraphim.vc. They also distribute via LinkedIn and a public newsletter. Earlier quarterly indices are archived on the same domain. For European context, cross-reference with ESA Space Economy and OECD's space-economy dashboard.
