Zero 2 Infinity is developing Bloostar, a rockoon launch system that uses a stratospheric balloon to lift a rocket to altitude before ignition, cutting fuel needs.
PRE-REVENUEZero 2 Infinity is a Spanish company based near Barcelona that uses high-altitude balloons for access to near space: it offers stratospheric payload flights (Elevate) and is developing Bloon, a crewed near-space balloon, and Bloostar, a balloon-launched rocket (rockoon) for small satellites.
Zero 2 Infinity is pioneering the rockoon concept with its Bloostar system, which uses a high-altitude balloon to carry a rocket to the stratosphere before igniting its engines. This approach significantly reduces the energy needed to reach orbit, potentially offering lower costs for small satellite launches. The company has conducted multiple balloon test flights and is working toward orbital capability. Zero 2 Infinity also offers near-space balloon services for testing and research.

Rockoon launch system: a stratospheric balloon lifts a three-stage methalox rocket built as concentric toroidal stages before orbital ignition. Suborbital test flight in 2017; no orbital launch yet.
