Constellation Space is a Y Combinator-backed company that aI operating system for mega-scale satellite networks. The company participated in the Winter 2026 batch of Y Combinator.
Constellation Space is building the autonomous infrastructure layer for the next generation of space networking. As satellite constellations rapidly scale from hundreds of nodes to tens of thousands, traditional ground-based orchestration fundamentally breaks down. ConstellationOS bridges this gap by providing zero-intervention network handoffs, predictive thermal load-balancing, and sub-second optical routing.
Constellation Space was part of Y Combinator's Winter 2026 cohort, has a team of approximately 4 employees, and is actively operating.
