About Onebrief

Onebrief makes military headquarters run seamlessly

Virtually everything in the military requires a plan—from everyday operations to war-time missions. With a rigorous process, many stakeholders, and rudimentary software (PowerPoint!!), planning is very slow. Onebrief is a collaborative software designed to make military planning fast. It turns every input into reusable building blocks and automatically keeps all planning artifacts in sync.
