Starcloud Raises $170 Million to Build Data Centers in Space, Reaching Unicorn Status 17 Months After Y Combinator
The Redmond, Washington-based startup closed a $170 million Series A led by Benchmark and EQT Ventures, valuing the company at $1.1 billion as it prepares to launch more powerful orbital compute satellites carrying Nvidia Blackwell chips.
Overview
Starcloud, a startup building data centers aboard satellites in low Earth orbit, has raised $170 million in a Series A round that values the company at $1.1 billion. The round was led by Benchmark and EQT Ventures, with participation from Macquarie Capital, NFX, Nebular, Y Combinator, Adjacent, 776 Ventures, Fuse Ventures, Manhattan West, and Monolith Power Systems, according to TechCrunch.
The funding brings Starcloud’s total capital raised to approximately $200 million and makes it the fastest Y Combinator graduate to reach unicorn status, just 17 months after its demo day presentation. Angel investors in the round include retired U.S. Air Force General Stephen Wilson, former Boeing CEO Dennis Muilenburg, and former Starbucks CEO Kevin Johnson.
Technology and Milestones
Starcloud launched its first satellite, Starcloud-1, in November 2025 aboard a SpaceX Falcon 9 rocket. The 60-kilogram spacecraft carried an Nvidia H100 GPU and achieved what the company described as the most powerful GPU compute ever operated in space by approximately 100 times over previous demonstrations, as reported by The Next Web.
The satellite trained a NanoGPT model on Shakespeare’s works entirely in orbit and ran a version of Google’s Gemini model in space. It has since been processing commercial radar data for Capella Space. One Nvidia A6000 GPU aboard the satellite failed during launch, though the primary H100 payload operated successfully.
The company’s next satellite, Starcloud-2, is scheduled to launch in October 2026 with a significant capability increase. It will carry multiple GPUs, including an Nvidia Blackwell chip and an AWS server blade, along with the largest deployable radiator on a private satellite, according to The Next Web. The company is also developing Starcloud-3, a 200-kilowatt, three-tonne spacecraft designed to fit SpaceX’s Starship deployment system, which Starcloud expects to be available around 2028 to 2029.
The Case for Orbital Compute
Starcloud’s pitch rests on a premise that is gaining traction among investors: terrestrial AI infrastructure is running into energy constraints that space can bypass. Satellites in orbit have access to continuous solar power, passive cooling via radiation into the near-absolute-zero temperatures of space, and no need for land acquisition, planning permissions, or grid connections.
CEO and co-founder Philip Johnston has framed this as an existential opportunity. “By moving AI compute to space, we unlock access to unlimited solar power and completely remove the energy bottleneck,” he told The Next Web.
The company’s long-term vision involves deploying an 88,000-satellite constellation that could serve as a distributed orbital compute network. Starcloud projects a target cost of $0.05 per kilowatt-hour for its orbital operations, though this depends on SpaceX reducing Starship launch costs to approximately $500 per kilogram.
Competitive Landscape
Starcloud is not the only company pursuing orbital data centers. SpaceX, which acquired xAI in February 2026, has sought regulatory permission for a million-satellite distributed compute network. Blue Origin filed in March for 51,600 orbital data center satellites, as previously reported. Google’s Project Suncatcher and startups including Aethero and Aetherflux are also developing space-based compute capabilities.
The scale challenge remains significant. For context, SpaceX’s existing Starlink constellation of approximately 10,000 satellites generates around 200 megawatts of power, while U.S. data centers currently under construction represent more than 25 gigawatts of combined capacity.
What Comes Next
The Series A funding will support Starcloud-3 development, the establishment of manufacturing capacity, and headcount growth. The company has signaled it may pursue another funding round as soon as this fall, potentially targeting $500 million at a $5 billion valuation, according to SpaceNews.
Whether orbital data centers can close the gap with terrestrial facilities remains an open question. The physics of solar power and passive cooling in orbit are favorable, but the economics of launching, maintaining, and replacing satellite hardware at scale are unproven. Starcloud’s rapid fundraising trajectory suggests investors are willing to bet on the possibility, even as the technical and economic hurdles ahead remain substantial.
