Onebrief Insights
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. Onebrief is more than just a software platform; it's a mission-driven company dedicated to improving the efficiency and effectiveness of military planning. By joining the team, you'll contribute to solutions that directly support national security and the work of service members. Your work directly addresses critical challenges that military planners and operators face daily. Every line of code and every design decision contributes to real-world outcomes. The software was designed and built by a team of experienced planners - lending a nuanced perspective on the challenges our partners face. Our team embeds alongside users - from the Pentagon to the Indo-Pacific - to build a platform that meets their unique needs. Rapid, Strategic Growth Our users love the platform and growth is scaling, most recently reporting operational usage growth at a 19,600% annualized rate. Stronger utilization is underway and we’re at an exciting period of advancement. As a rapidly growing organization, you'll directly influence its direction and long-term success. Over the past year we’ve seen exciting growth metrics: First, our headcount has grown 150% YoY to keep pace with our product advancement and customer growth.
