US-based space computing startup StarCloud has reached a valuation of $1.1 billion after its latest funding round, marking one of the fastest rises to unicorn status among Y Combinator graduates.
The Series A round, led by Benchmark and EQT Ventures, highlights growing interest in orbital data centers as demand for computing power surges.
StarCloud intends to move data processing operations to outer space as this method would enable the company to circumvent both energy limitations and existing Earth-based infrastructure systems.
The company has already launched a satellite equipped with an Nvidia H100 chip and plans to deploy more advanced systems, including GPUs based on Nvidia’s Blackwell architecture and server hardware from Amazon Web Services.
The startup is developing a larger spacecraft, StarCloud 3, designed to launch on SpaceX’s reusable rocket, Starship. According to CEO Philip Johnston, data centers built in space will achieve similar cost efficiencies with existing ground-based systems when launch expenses are reduced to more affordable levels.
Additional time is required until the Starship system reaches operational status, which will allow businesses to use it during the current decade.
Running high-performance chips in space presents major challenges including cooling requirements and power generation needs and the need to synchronize multiple GPUs. Current deployments are small compared to Earth-based infrastructure where millions of GPUs are already in use.
StarCloud reports that it has made its first achievement with a space-based computer system by training an AI model in orbit despite existing difficulties.
Starcloud is also one of the contenders in the space race. Other tech companies, EtherFlux and Atheoro, along with Google’s Project Suncatcher, which started the initiative, are investigating the development of space-based data centers. SpaceX has developed plans to build an extensive satellite network that will support decentralized computing operations.
