AstroForge

HQ Seal Beach, United StatesFounded 2022

AstroForge is pioneering the field of asteroid mining, aiming to extract valuable minerals from space to meet Earth's growing resource demands. By focusing on platinum-group metals (PGMs), which are essential for technologies like catalytic converters, clean energy solutions, and medical instruments, AstroForge seeks to provide a more cost-effective and environmentally friendly alternative to traditional terrestrial mining methods. Their mission involves developing in-space refinery technology to source these metals from near-Earth asteroids, thereby reducing the environmental impact associated with conventional mining practices.
