TechCrunch·high signal

Starcloud, which builds orbital data centers to bypass terrestrial energy constraints for AI compute, raised a $170M Series A led by Benchmark and EQT Ventures, reaching unicorn status 17 months after YC demo day — the fastest in Y Combinator history. The company launched its first satellite with an NVIDIA H100 GPU in November 2025 and will deploy Starcloud 2 later this year with Blackwell chips, an AWS server blade, and a bitcoin mining computer.
