# HyImpulse’s €50M Series A Close: Paraffin Rockets With a €350M Order Book

> JOIN Capital and Ace Capital Partners co-led €50M to finish HyImpulse’s Series A near €100M — German hybrid propulsion startup cites €125M total capital (equity + grants) and a €350M order book ahead of SR75 and SL1 flights.

**JOIN Capital** and **Ace Capital Partners** co-led **€50 million** to close **HyImpulse’s** Series A at nearly **€100 million**, reported **September 2, 2026** by Resilience Media. New money includes North Ventures, BW-Capital, Bayern Kapital, and Germany’s **DLR**, with Campus Founders Ventures and other existing holders returning.

**Spine:** Europe needs launch capacity with **working economics** — HyImpulse claims paraffin hybrid rockets with roughly **half the parts** and a path to **half the cost per kilogram**, plus a **€350M** order book **before** a commercial flight.

## Key facts

| Field | Detail |
| --- | --- |
| Company | [HyImpulse](/startup/hyimpulse) (Germany; DLR spinout, founded 2018) |
| Round | **€50M** Series A close (~€100M Series A total) |
| Total capital | **~€125M** equity + grants (CEO) |
| Co-leads | JOIN Capital; Ace Capital Partners |
| Order book | **~€350M** (company claim) |
| Near-term | SR75 at SaxaVord (Shetland); SL1 maiden flight planned |
| Valuation | **Not disclosed** |

## Who uses the product — and for what job

**Users:** satellite and payload customers needing dedicated, affordable access to space — plus future hypersonic / suborbital test services.

**Job:** book launch (and later in-space mobility via HyMove) on a European hybrid-propulsion stack positioned against 1960s-heritage liquid architectures.

Payload specs cited by Resilience Media: SR75 up to **250kg** suborbital; SL1 up to **~600kg** to LEO; HyMove for up to **~400kg** payloads.

## Why now

- Over-demand for dedicated launches vs available cadence (SpaceX included) is the market backdrop investors are underwriting.
- Germany’s sovereign space push + DLR lineage give industrial credibility.
- Flight tests (including a 2024 Australia pilot) de-risk the architecture enough for a Series A close — commercial debut still ahead.

## Why JOIN and Ace — portfolio fit

| Investor | Fit |
| --- | --- |
| JOIN Capital | European deep-tech; Jan Borgstädt cites leaner architecture and proven flight tech |
| Ace Capital Partners | Space / launch economics thesis (Shimon Tsentsiper on dedicated affordable launches) |
| DLR / Bayern Kapital | Sovereign industrial alignment |

**Likely founder rationale:** finish the Series A with **European industrial + deep-tech** capital that understands grant stacking and launchpad politics — not a US growth fund optimizing SaaS multiples.

*JOIN, Ace, North Ventures, BW-Capital, Bayern Kapital, and Campus Founders are covered without inventing `/fund/` pages.*

## Competitive map

| Player | Geo / angle |
| --- | --- |
| HyImpulse | Paraffin hybrid; DE / UK launch path |
| Isar Aerospace | German orbital competitor |
| PLD Space | Spanish small launch |
| SpaceX | Dominant cadence; different price/access funnel |

## What is not proven

- **No commercial rocket launched yet** — order book is demand signal, not recognized revenue.
- Cost-per-kg “half” claim is **founder/investor framing**, not audited flight economics.
- Equity vs grant split inside the €125M total is not itemized.

## Practical takeaway

- **Founders (space):** A €350M order book without flight is powerful *and* fragile — diligence conversion clauses.
- **Investors:** Separate propulsion novelty from launch-site and regulatory execution risk.
- **Payload buyers:** Watch SR75 SaxaVord and SL1 maiden results before treating the backlog as capacity.
