Besxar: Orbital semiconductor manufacturing
Ashley Pilipiszyn founded Besxar in 2023 to manufacture semiconductor wafers in the ultra-high vacuum of space, yielding higher-performance chips for AI infrastructure.
By taking wafer manufacturing to the vacuum of orbit, Besxar produces semiconductor substrates aimed at the AI data centers and defense systems where current chips are already throttled by heat.
Besxar is an American semiconductor company manufacturing wafers in the ultra-high vacuum of space. The approach yields better-performing chips than conventional terrestrial fabrication, addressing the AI infrastructure demands that are pushing today’s GPUs to thermal limits.
Founded in 2023 by an early OpenAI employee, Besxar operates reusable orbital foundries (Fabships) that take semiconductor manufacturing off-planet. The company has signed a 12-mission agreement with SpaceX to fly Fabships aboard Falcon 9, and is an early member of NVIDIA’s Inception program.
Conventional semiconductor fabrication is constrained by the cleanroom environments of Earth. Besxar relocates the process to orbit, where the ultra-high vacuum of space enables wafer production with greater material purity than is achievable on the ground. The company frames AI data centers and defense applications including directed-energy weapons as markets where current chip performance is already throttled by thermal limits, and where vacuum-grade substrates open new headroom.
Chips made in space, built for AI infrastructure on Earth.
