Laith Altarabishi is Co-Founder of Constellation Space, an AI-powered operating system for satellite constellation management. The company is part of Y Combinator's Winter 2026 batch and is based in Seattle, WA.

Laith studied computer engineering with a focus on machine learning and computer systems at the University of Texas at Austin. He has a deep interest in the intersection of ML and computer systems.

The founding team spent years building and operating satellite systems at SpaceX, Blue Origin, and NASA before starting Constellation. They founded the company to solve the problem that reactive monitoring does not scale for satellite constellations.

Constellation Space builds ConstellationOS, which predicts satellite link failures with 90%+ accuracy and autonomously reroutes traffic in under 2 seconds. The platform processes over 100,000 telemetry messages per second from satellites, ground stations, and weather systems.

As satellite constellations scale from hundreds to tens of thousands of nodes, network failures cost the industry $2.5 billion per year. ConstellationOS provides zero data loss and zero human intervention, addressing a critical infrastructure need for the future of space telecommunications.
