ABOUT ONEBRIEF

Onebrief builds collaboration and AI-powered workflow software for military planning and operational coordination.

Today, many critical planning workflows still rely on fragmented systems, static documents, and disconnected tools that make collaboration and decision-making unnecessarily difficult.
