Starcloud

Earth-bound data centers are hitting hard limits just as AI demand goes vertical. Starcloud moves compute to orbit — in 2025 it successfully deployed and ran inference on the first GPUs ever sent to space.

For YC founders, by YC founders

We invest exclusively in YC founders because it's the most concentrated startup ecosystem in the world. As YC alumni ourselves, we know the community from the inside — and the data shows why that focus matters.
