Onebrief

Honolulu, Hawaii, United States · Founded 2019

Onebrief makes collaborative planning software for military staffs, which it calls an operating system for modern command. U.S. military headquarters use it to build and brief operational plans, and it is the planning layer in the U.S. Army’s Next Generation Command and Control prototype. In January 2026 it acquired Battle Road Digital, maker of the AtomEngine wargaming and simulation platform.
