Onebrief

Onebrief develops what it calls the Command Decision Platform, software for military headquarters and staffs that unifies operational data, collaborative planning, agentic AI workflows and continuous wargaming in a single workspace. The platform structures content into reusable "Cards" that propagate changes across every product built from them, enabling staffs to produce and update presentations, command-and-control (COMREL/task organization) charts, long-form documents, plans and orders, whiteboards, timelines and maps with military symbology from a single live dataset. Collaborative editing and cross-plan synchronization are intended to keep dozens of echelons — from national command authorities down to tactical units — working from the same current picture.

The product is deployed across classified, unclassified and partner networks, including SIPR and JWICS, with redundant architecture aimed at operating in Denied, Disrupted, Intermittent or Limited (DDIL) conditions and at the tactical edge. A bidirectional, policy-aware API connects mission data sources such as Maven Smart System and Advana, and imports from Word, PowerPoint, Excel and PDF are converted into structured Cards. AI features — built on Anthropic Claude and trained on open-source U.S. military doctrine, historical orders and staff outputs — draft, summarize and explain plans and orders, support automated intelligence processing, multi-domain coordination and course-of-action development, while keeping decision authority with commanders. Other capabilities include audit logging and version control, per-item automated classification marking, access controls and coalition features such as disclosure handling and translation.

The company reports customer-observed outcomes including workflows completed roughly three times faster, a 70% reduction in planning cycle time, 500 hours saved during a 10-day exercise and 400 people-hours saved by replacing a multi-day conference.

Business model

Onebrief sells its software platform to military and government organizations, deploying it across command headquarters and unclassified, classified and coalition partner networks, with onboarding, in-app training and hands-on customer support. It positions itself within the commercial off-the-shelf software category the U.S. Department of Defense is prioritizing.

Traction

As of the Series C extension in June 2025, Onebrief reported user hours growing at a 19,600% annualized rate, adoption in four of the seven geographic combatant commands, users reporting 2x efficiency gains, and use across U.S. military headquarters worldwide. Company materials cite 350+ employees, 120% year-over-year team growth (nearly 130% at the time of the Series C), 45% veterans, staff in 33 U.S. states, and a $2.15B company valuation.

Latest developments

Following the June 2025 Series C extension, Onebrief said it would deepen investment in wartime resilience, reach and AI, expand engineering and infrastructure to support allied and joint operations and up to 100,000 simultaneous collaborators, and scale user productivity 100x within three years. Current company materials describe the product as the Command Decision Platform, adding agentic AI workflows, AI modeling and simulation, and continuous wargaming, and cite 350+ employees and a $2.15B valuation.
