What Arkadia Space does
Arkadia Space is a privately held Spanish space propulsion company founded in 2020 and headquartered at Castellón Airport in Benlloch, Spain. It designs, manufactures, and commercializes engines and propulsion systems based on high-test hydrogen peroxide (HTP) and its patented ARKFUEL19 proprietary fuel, positioning these as non-toxic, ITAR-free alternatives to hydrazine-based propulsion. The company operates Europe's first private propulsion test center, spanning approximately 3,000 square meters with three operational test benches, and became the first European entity to fly hydrogen peroxide-based propulsion in orbit with its DARK mission on SpaceX Transporter-13 in March 2025.
The product portfolio spans monopropellant thrusters (PLANKTON 1N, TRITON 5N, OBERON 50N, ARIEL 250N), bipropellant engines (GHOST 100N, PHANTOM 200N), piston propellant tanks in 2L and 7L sizes, and fully customizable propulsion modules integrating tanks, thrusters, and in-house electronics. These systems are sold directly to satellite manufacturers, launcher companies, re-entry vehicle developers, lander programs, and spaceplane developers, with use cases including attitude and orbit control, orbit transfer, station-keeping, collision avoidance, end-of-life deorbiting, and reaction control. Pricing is quote-based with delivery in under 6 months for components and under 9 months for complete systems, framed against an up to 70% cost reduction versus traditional hydrazine systems.
The go-to-market is enterprise direct sales targeting European aerospace primes and emerging space startups. Named customers include MaiaSpace (launcher RCS thrusters), Dassault Aviation (VORTEX-D spaceplane propulsion), Reflex Aerospace (200kg LEO satellite propulsion), and D-Orbit (in-orbit validation host). Revenue model is hardware sales of integrated propulsion modules and individual components, supplemented by grants and ESA development contracts. The company has raised approximately €17.3M to date across a €2.8M seed round (October 2023, Draper B1 and Expansion Ventures) and a €14.5M EIC Accelerator tranche (March 2026), and is actively pursuing Series A while scaling headcount from 28 toward 40-45 employees by end of 2026.
