Leanspace raises €10 million Series A round to bring software-defined satellite operations to enterprise and institutional space programs STRASBOURG, November 17th, 2025 – Leanspace, a European satellite operations technology provider, today announced it has raised €10 million in Series A funding. The financing round includes new strategic investors: ISAI Cap Venture, Capgemini’s corporate venture arm, and Qwaltec, a US-based space and defense contractor, alongside historical investors specializing in space, defense, and enterprise software: VC firms 42CAP and Karista, and Arnaud Guérin, co-founder of military AI platform Preligens. Additional non-dilutive funding comes from Caisse d’Epargne and Bpifrance via the France 2030 strategic investment plan. The space industry is undergoing a rapid transformation with the rise of satellite constellations, dynamic missions, and increasing security demands. Yet, the technologies to operate space programs have struggled to keep pace, creating cost and complexity for spacecraft operators. With this new financing round and strategic alliances, Leanspace will accelerate the shift to software-defined satellite operations across European and North American markets. Founded in 2020, Leanspace has developed a software platform for satellite and ground segment operations that has been flight-proven and trusted by more than 20 spacecraft operators worldwide, with an initial focus on small satellite missions with customers such as Quantum Space (USA), Look Up (France), and Clearspace (Switzerland). Since 2024, the company has expanded into the enterprise and institutional markets, having already secured 7 contracts with space agencies and leading primes in Europe, the US, and Asia, such as Airbus Defense & Space (France), Hispasat (Spain), and the European Space Agency. Leanspace currently addresses 6 market segments: small satellites, in-orbit services vehicles, satellite constellations, launchers & spaceports, large satellites, and ground station networks. The Leanspace platform provides a wide range of software products across satellite monitoring & control, mission planning, ground segment orchestration, and testing of space hardware. Thanks to its new strategic industrial investors, Leanspace is now accelerating its expansion into large, high-complexity, and security-critical space programs. Leveraging the platform and its open customization model, the new industrial partners will deliver turnkey mission operations systems and provide additional value with managed services, operations engineering support, and local compliance with national security requirements in both Europe and the US. “Software-defined satellite operations solve the key challenges of modern space programs: agility, resilience, and cost efficiency,” said Guillaume Tanier, CEO of Leanspace. “This new financing round and strategic partnerships bring heritage and execution power, reinforcing our credibility as expected by major enterprise, civilian, and military customers. This supports our goal to be a trusted infrastructure for complex space programs and validates our long-term vision of becoming the technological de facto standard around the world.” Around its platform, Leanspace is building a global ecosystem of industrial partners. The company is welcoming additional players – satellite manufacturers, software integrators, cloud providers, SSA, GSaaS, and other providers of space services – to join and build the software-defined space industry of the future.
