Modularity Space

Modularity Space is a US-based satellite technology company founded in Daytona Beach, Florida, developing reusable, modular satellite platforms called HOST (Hosted On-orbit Spacecraft and Technology) that can carry multiple payloads in LEO and be upgraded, refueled, and refurbished in orbit. HOST satellites are approximately the size of a mini-fridge and are designed to host multiple third-party payloads on a single platform, reducing individual payload launch costs. The company provides mission planning, operations, licensing, engineering, and project management services alongside the satellite hosting platform, targeting commercial, research, and government customers who need affordable access to orbit without building and operating their own satellite. Modularity Space offers full-service in-orbit payload hosting as a commercially viable alternative to dedicated satellite development.
