Investment: “ArcSpace raises over €2 million”
ArcSpace, a Paris-based SpaceTech startup developing technology for in-orbit satellite repair, assembly, and servicing, has closed a funding round of over €2 million. The round was led by DEPO Ventures through its DEPO Ventures One fund.
The round also included SCE Freiraum Ventures, IRDI Capital Investissement and a French Business Angels network.
Founded in 2022, ArcSpace was co‑founded by Guillaume Mohara, who serves as CEO. The company provides manufacturing tools and processes for use in space. Its proprietary Electron Beam technology enables joining, welding and cutting directly on board spacecraft and lunar rovers. The compact system can be deployed aboard a spacecraft, produces no hazardous waste during operation, and the company says it can safely and precisely cut, join and weld materials even in the vacuum of space. ArcSpace highlights its ability to capture and repair satellites that were not originally designed for servicing, and says it has attracted interest from more than a dozen commercial companies while collaborating with institutional partners including the French space agency (CNES), the European Space Agency (ESA) and the European Defence Fund (EDF).
The company plans to use the capital to support its next stage of growth, primarily through team expansion, qualification of its flight hardware and preparations for its first demonstration mission planned for 2027, with a target to bring the product to market by 2028.
“Artificial intelligence, defence technologies, and space are among the sectors where Europe’s future champions are being built. ArcSpace offers a breakthrough solution capable of repairing satellites that were never intended to be serviced. This capability significantly reduces risk and strengthens the resilience of critical infrastructure that our societies increasingly depend upon. At DEPO Ventures, we focus precisely on innovations of this kind with global relevance and long-term strategic impact,” said Petr Šíma, Partner at DEPO Ventures.
Guillaume Mohara, CEO and co-founder of ArcSpace, said, “The space industry has traditionally operated on a one-time-use model. When something failed or a satellite ran out of fuel, infrastructure worth hundreds of millions of euros was lost. At ArcSpace, we believe that the ability to manufacture, repair, and modify equipment directly in orbit is the only way to build a sustainable and secure space economy. Our technology recently passed demanding space environmental testing, including high-vacuum and mechanical vibrations. This new funding will allow us to accelerate in-space validation of our solution, demonstrating more than 100 seconds of fully autonomous welding aboard a spacecraft in 2027, a world first.”
