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 Mission Driven Onebrief is composed of professionals from backgrounds of all kinds - spanning veterans across forces and organizations and technologists from leading-edge software giants.
