Overview

Constellation Space builds ConstellationOS, an AI-powered operating system for large satellite networks. It acts as an autonomous infrastructure layer that ingests telemetry from satellites, ground stations, and weather systems to predict link failures with over 90% accuracy, issuing a five-minute warning and autonomously rerouting traffic in under two seconds to prevent data loss without human intervention. The platform targets satellite operators and seeks to replace reactive NOC playbooks by enabling proactive, automated network management at mega-constellation scale. The team comes from SpaceX, Blue Origin, and NASA, lending domain experience, and the company aims to reduce industry losses from network failures (estimated at $2.5 billion annually) by improving resilience and efficiency. Financially, the company progressed from Y Combinator's Winter 2026 batch with a $500K accelerator round to a $6.5M seed in March 2026 led by SGH Capital, to fund platform development and expansion.
