HyPrSpace
Overview
Develops patented hybrid (solid fuel + liquid oxidizer) rocket engines and small launchers, selling dedicated, lead and shared smallsat launch, with dual-use defense propulsion as a nearer-term revenue line.
Moat: A patented thin annular combustion chamber holds combustion efficiency roughly constant regardless of engine scale — the specific barrier that has kept hybrid propulsion out of orbital launch for ~50 years — plus recycled-HDPE fuel that is cheap, inert and simple to handle.

Key Products
- Baguette Onedevelopment
Suborbital demonstrator; targeted as the first rocket launched to space from mainland France.
- OB-1 (Orbital Baguette 1)development
Orbital microlauncher with CNES as a customer, selected March 2025 among four French launch companies.
Near-term Catalysts
- 2026
Baguette One first suborbital flight
Flight-validates hybrid propulsion at scale and would be the first rocket launched to space from mainland France.
- 2027
CNES launch contract for OB-1
A sovereign anchor customer, which most European microlauncher startups lack; first launch attempt targeted late 2027.
Top Risks
- First-flight failure risk on a novel propulsion architecture with zero orbital heritage anywhere in the industry.
- A severely overcrowded and capital-starved European microlauncher field (Isar, RFA, PLD Space, Latitude, MaiaSpace, Orbex, Skyrora).
- ~€56M raised is an order of magnitude below what peers have needed to reach orbit — a Series B is the next gating event.
