Onebrief raises $200M at $2.15B valuation, acquires Battle Road Digital – News

Defense technology company Onebrief Inc. announced today that it had raised $200 million in new funding on a valuation of $2.15 billion and that it had used the new funding to acquire Battle Road Digital Inc., a technology company that applies advanced simulation and game-inspired software to defense and broader strategic challenges.

Founded in 2019, Onebrief builds collaborative software that is designed to modernize how military staffs plan, coordinate and execute operations.

The company’s platform replaces traditional, fragmented tools such as static documents, spreadsheets and email chains with a real-time, artificial intelligence-assisted workflow system that keeps all participants synchronized. Support is offered for complex planning processes by turning inputs into structured building blocks, automating repetitive tasks and helping teams share a single source of truth for operational plans.

Onebrief describes its platform as an “operating system for modern command” in that it enables rapid decision-making and collaboration across distributed teams and organizational levels. The platform is also aimed at reducing the time it takes to prepare operational plans from days or weeks to hours or minutes, important in rapidly evolving military contexts.

Onebrief’s Series D round was led by Battery Ventures LP and Sapphire Ventures LP, with Salesforce Ventures, General Catalyst and Insight Partners LP also participating.

“Since we first invested in Onebrief in early 2025, the company has continued to demonstrate a clear vision and proven strategy for deploying game-changing software to the military,” said Michael Brown, general partner of Battery Ventures. “We’re excited to reaffirm our commitment to the company in this new funding round.”

Battle Road, the company Onebrief is using some or all of the new funding to acquire, was founded in 2021 and applies advanced simulation and game-inspired software to defense and broader strategic challenges.

The company’s main offering is AtomEngine, a cloud-first, large-scale simulation platform that can model extensive environments, including terrain, weather, infrastructure and interactive AI-driven entities, for use in wargaming, mission planning, training and analysis.

Battle Road’s platform allows users to simulate complex scenarios at scale, from detailed tactical engagements to intricate operational exercises involving multiple domains.

The platform also supports real-time interactions, multi-user sessions and integration with existing command-and-control systems to allow planners and commanders to explore how different decisions might play out under various conditions.

“Integrating with Onebrief allows us to rapidly bridge the gap between simulation and live operations,” said Josh Henderson, founder of Battle Road. “This partnership is about developing a platform that provides commanders with powerful new tools to explore tomorrow’s fight today while preserving valuable lives, time and resources.”

Coming into its acquisition, Battle Road had raised a single seed round of $5 million, according to data from PitchBook. Investors in the company included DNS Capital and Konvoy Ventures LP.
