What Infostellar does
Infostellar is a Tokyo-headquartered space technology company founded in 2016 that operates a cloud-based Ground Segment as a Service (GSaaS) platform under the brand StellarStation. The platform provides satellite operators with on-demand access to a global network of ground stations covering V/UHF, S-Band, X-band, and Ka-band RF spectra, supporting missions from single spacecraft to large constellations across LEO, MEO, GEO, cisLunar, and planetary orbits. Core offerings include the StellarStation cloud platform, the GS Network Service for downlinks, uplinks, and real-time TT&C, antenna hosting at Japan sites, full technical services (spectrum licensing, site sourcing, program management), and regulatory support.
The company's business model is B2B infrastructure-as-a-service, monetized through recurring subscriptions for GSaaS access, managed services for antenna hosting, and project-based technical/regulatory services. Go-to-market is direct enterprise sales to satellite operators, multi-national satcom providers, and remote-sensing/Earth observation companies. Strategic emphasis is on software-defined, API-driven ground operations that consolidate fragmented legacy ground infrastructure.
Founded by co-founders including CEO Naomi Kurahara, Infostellar has raised approximately $22.4M in equity across multiple rounds through 2021, with backers including Mitsubishi Corporation, ITOCHU, Sony Innovation Fund, Airbus Ventures, and Pavilion Capital. Recent strategic activity (2025-2026) includes partnerships with Antaris (AI mission planning), Fusic (AWS cloud), Pramatra Space (QKD networks), XDLINX, and RAISE4, signaling platform-level ecosystem expansion rather than reported revenue acceleration.
