Sateliot Raises €100M for 5G Satellite Network Expansion

Spanish satellite connectivity firm Sateliot is launching a significant €100 million Series C funding round to accelerate the global deployment of its innovative 5G satellite constellation. This capital infusion, expected to conclude by summer, aims to bolster the company's commercial execution and expand its orbital infrastructure, positioning it as a key player in European digital sovereignty.

The funding round, primarily structured as equity with potential debt components, follows a successful €70 million Series B raise in March 2025. Sateliot CEO Jaume Sanpera highlighted the scale and timing of this latest round, emphasizing its role in consolidating a European 5G satellite connectivity backbone. The company anticipates up to 50% public co-financing through match funding mechanisms, underscoring its strategic importance to national and European digital initiatives.

This new funding places Sateliot among notable recent capital raises in the European SpaceTech sector. Comparable rounds include France's Look Up (€50 million for space traffic management), UK-based Spaceflux (€6.1 million for satellite tracking), Spain's Kreios Space (€8 million for propulsion technology), Germany's Reflex Aerospace (€50 million for satellite platforms), France's U-Space (€24 million for industrial scaling), and France's Infinite Orbits (€40 million for satellite servicing). These figures collectively illustrate robust investor confidence in the burgeoning satellite services market.

Sateliot has already secured substantial commercial traction, reporting over €270 million in pre-contracts with more than 400 clients across 60 countries. Strategic partnerships with major telecommunications operators, including Telefónica and Deutsche Telekom, further validate its business model. The company's technology enables unmodified commercial NB-IoT devices to connect directly to its Low Earth Orbit (LEO) satellites, seamlessly integrating terrestrial and satellite networks for affordable global 5G coverage in underserved areas.

The capital will be primarily directed towards completing the deployment of Sateliot's constellation of 16 satellites. Six satellites are already operational, with five more slated for launch in 2026. This expansion is crucial for supporting Internet of Things (IoT) use cases and demonstrating 5G New Radio technology capabilities, including voice, video, and data transmission directly from space. The next generation of Tritó satellites is planned for launch in 2027.

Founded in 2018, Sateliot has consistently attracted significant backing from a diverse group of investors. Previous funding rounds have seen participation from industrial, institutional, and financial entities such as Indra, Cellnex, the Spanish Society for Technological Transformation (SETT), Sepides (SEPI), Hyperion, Global Portfolio Investments, and Banco Santander. Additionally, the company has benefited from financing support from the European Investment Bank (EIB), underscoring its alignment with European technological development goals.
