Inside Starcloud’s $2B Space Factory
Philip Johnston, Ezra Feilden, Adi Oltean, Bailey Montaño, Miguel Rivera, Camilo Lopez, Molly O'Shea
Seattle-based StarCloud, founded by Philip Johnston and Ezra Fieldin, is advancing its $2 billion valuation by transitioning from its successful StarCloud 1 mission to the assembly of StarCloud 2, a satellite designed to deliver space-based compute power at a fraction of traditional aerospace costs. The company is engineering a proprietary constellation of 88,000 satellites capable of deploying 20 gigawatts of processing capacity by leveraging SpaceX Starship launches and innovative thermal management systems to eliminate terrestrial infrastructure dependencies. With current workloads running government inference tasks and AI models like NanoGPT in orbit, StarCloud aims to scale production to 100 units weekly by 2028 while leveraging the physical and legal security of orbital assets for critical defense applications.

Inside The Startup Launching AI Data Centers Into Space
Aaron Epstein, Philip Johnston, Ezra Feilden, Adi Oltean, Addy
Launched on November 2nd via a SpaceX rideshare mission, aerospace startup StarCloud successfully deployed the first orbital data center, StarCloud One, which houses an NVIDIA H100 GPU to operate 100 times more powerfully than previous space computers. Founded in Summer 2024 by CEO Philip Johnston, Microsoft veteran Addy, and NASA alumnus Ezra, the team rapidly pivoted from solar power concepts to orbital compute to leverage cheaper launch costs for massive, sun-synchronous facilities that utilize deep space for cooling. With a second satellite featuring NVIDIA Blackwell architecture scheduled for October 2025, StarCloud aims to scale to 40-megawatt centers that bypass terrestrial constraints on land and water while validating high-performance workloads like model training in the vacuum.
