100-word summary
Starcloud just raised $170 million at a $1.1 billion valuation, making it Y Combinator's fastest unicorn just 17 months after demo day. The company runs AI computation on satellites, not in data centers. Benchmark and EQT led the Series A, betting that running workloads in orbit solves heat dissipation problems that plague ground-based chips. Starcloud already has deals with AWS, Google Cloud, and Nvidia, and its next satellite launches later this year with the largest deployable radiator ever flown. The money funds a dedicated manufacturing facility and future launch contracts. Turns out the ultimate cooling solution for power-hungry AI chips isn't liquid nitrogen; it's the vacuum of space.
