Cowboy Space Corporation is building a power grid in outer space for artificial intelligence. Using an integrated system of satellites and rockets, we will send high-performance compute and optical data transmission to Low Earth Orbit. Our constellation of satellites, Stampede, will harness abundant solar power to run on-orbit GPU data centers. With each launch, Stampede grows the power and compute capacity for humanity. Earths energy grid cant run at the pace of AI. We can. AI is driving the largest infrastructure buildout in recent history, and the power grid on planet Earth cant keep pace. In major US markets, average grid connection lead times for new data centers can run 5-7 years or more. Meanwhile, AI demand is flat-out outgrowing Earths pastures. Full-Stack Architecture: Traditional architecture treats the rocket as a workhorse and the satellite as freight. In our system, the rockets upper stage is the satellite itself. Its a 1-megawatt data center with active thermal management and integrated compute, designed as one unified vehicle from the ground up. We trim the fat on redundant structure and avionics, dedicating every possible kilogram of compute to Low Earth Orbit. By owning our manufacturing and dedicated launch sites, we vertically integrate core technologies that enable deploying compute at scale. We’ve raised a $275M Series B at a $2B valuation led by Index Ventures, with participation from new investors IVP, Blossom Capital, and SAIC, alongside existing investors Breakthrough Energy Ventures, Construct Capital, Andreessen Horowitz, NEA, Interlagos and Baiju Bhatt.
