We build intelligent, autonomous systems that protect shorelines and create $10T+ worth of new coastal land, islands and peninsulas.

Coastal Assembly PBC (“Coastal”) is building intelligent, autonomous systems to protect shorelines from erosion and sea level rise and to use the same technology to create $10T+ of entirely new coastal land, including islands and peninsulas. We believe programmable coastal land protection and creation is a $1T+ category unlocked by AI.
Born out of MIT’s Self-Assembly Lab, Coastal brings together nearly a decade of research in growing islands and coastlines with deep expertise across coastal architecture, physics, computer science, and autonomous systems.
Our work has received global recognition, with features in TED, CNN, and Business Insider. Now we are commercializing the next generation of coastal infrastructure. Join us.
