Philip Johnston, Co-founder & CEO, Starcloud | Slush 2025
summary
Company launches first AI data center grade chip to orbit: a NVIDIA H100 on a 60 kg small sat that will run commissioning, train a model and do high‑powered inference on satellite imagery and a Google Cloud Gemini derivative. Next launch in October carries 100× power and a huge radiator; full scale reaches Starship‑size 5 GW platforms with 4 km × 4 km solar arrays. Economics hinge on a ~$500/kg break even versus Earth solar; engineering focuses on deployable radiators and radiation testing at Knoxville and Brookhaven.
