The platform supports complex military processes, including deployment solutions, offline capabilities, AI Co-planner, and wargaming for course-of-action development, and is used across U.S. military headquarters, integral to three of the four largest global OPLANs. On January 13, 2026, Onebrief closed a $200 million Series D funding round, including both primary and secondary capital, led by Battery Ventures and Sapphire Ventures, with participation from Salesforce Ventures, General Catalyst, and Insight Partners. The round valued the company at a post-money valuation of $2.15 billion, following a Series C at $1.1 billion pre-money valuation seven months prior, bringing total funding to $311 million. Proceeds will expand AI Assist product, ensure wartime resiliency, scale operations, and grow the team toward over 500 employees. Concurrently, Onebrief acquired Battle Road Digital, a simulation and wargaming software startup founded in 2021 that raised $5 million in seed funding. Battle Road's AtomEngine adds real-time wargaming, operational modeling, terrain simulation, and AI-driven entities to Onebrief's platform, bridging simulation and live operations for enhanced military decision-making. The funding reflects surging investor interest in defense tech amid government spending on AI, software, and data for military modernization. Onebrief, founded in 2019 and based in Honolulu, has demonstrated rapid growth, earning trust across U.S. combatant commands and positioning for global defense market expansion. |

In January 2025, Onebrief closed a $200 million Series D round, including primary and secondary offerings, at a post-money valuation of $2.15 billion, doubling from its prior $1.1 billion valuation in a $20 million Series C six months earlier in June 2024. The Series D was led by Battery Ventures and Sapphire Ventures, with participation from new investor Salesforce Ventures and additional investments from General Catalyst and Insight Partners. Battery Ventures, which first invested in early 2025, reaffirmed its commitment, highlighting Onebrief's vision in defense tech. Proceeds fund expansion of the AI Assist product, wartime resiliency, rapid scaling, and platform enhancements to solidify its role in command operations. Concurrently, the funding enabled acquisition of Battle Road Digital, a defense innovation firm specializing in gaming technology for real-time operational decision support, wargaming, and simulation, integrating these capabilities into Onebrief's ecosystem. This bolsters superhuman military command by bridging simulation and live operations. Onebrief has now raised over $311 million total, positioning it as a unicorn in the surging defense tech sector amid rising government investments in AI, software, and data for military modernization. |

Investors were chosen for defense expertise to accelerate modernization of military decision-making in dynamic environments. General Catalyst highlighted Onebrief's advantages in rapid planning observed by retired military partners, while Insight Partners emphasized its transformative impact on defense tech for global stability.

This round included primary and secondary capital, enabling acquisition of Battle Road Digital for simulation/wargaming tech to integrate real-time modeling into Onebrief's platform, enhancing AI Assist and wartime resilience. Total funding reached $311M+ post-$200M. The funding supports scaling as the backbone for command operations unifying planning, simulations, and decisions. Defense tech investment hit record $7.7B across ~100 VC deals in 2025 amid rising global conflicts and government modernization spend on software/AI. |
