What We Do
Before Onebrief, military planning and collaboration was slow, inefficient, and resource-intensive. Building slides with no version control as partners collaborated would have staffs spend weeks or months on a single product or document.
With Onebrief, these workflows are now simple and collaboration between large commands is efficient. Staff optimization is the key to building a more resilient, more effective military. Today Onebrief users report at least 2x time savings - and growing.
Onebrief is a first of its kind software for the military. While many others have tried to build a solution for this problem, Onebrief’s “card” structure for reusing data and enabling real time updates is what makes this possible. Core features and attributes that make this platform powerful include:
- Global Collaboration
- Real-Time Updates
- AI Automation
- Interoperability + Integrations
- Deployable across Secret and Top Secret Networks
