Spanish developer of stratospheric balloon capsules for near-space tourism and high-altitude civil/military programs.
EOS-X Space (Edge Of Space Xperience) designs and operates pressurised capsules lifted by stratospheric balloons to provide near-space tourism flights to an altitude of around 40 kilometers. Flights carry up to eight or nine passengers plus a pilot for several hours, including time cruising at the edge of space, before a helium-balloon descent back to the surface.
Beyond tourism, the company is developing civil and military high-altitude technology programs, including plans for satellite-related observation and communications applications. In July 2025, EOS-X Space acquired the US stratospheric balloon company Space Perspective, which had ceased operations earlier that year, to support its planned entry into the US market.
The company has raised significant late-stage capital in 2026, including a $140 million Series D in May and a $120 million growth round led by Global Emerging Markets in November, reaching a reported $1.2 billion valuation. EOS-X Space has stated plans to pursue a stock market listing in New York and London following the start of commercial operations.
