War Games, Now a Balance-Sheet Item
War is becoming a software problem, and the software just got $200 million richer.
Onebrief, the Honolulu military command software company, closed a $200 million Series D at a $2.15 billion post-money valuation, more than doubling its prior mark. The round mixed primary and secondary shares. Battery Ventures and Sapphire Ventures led; Salesforce Ventures joined as a new investor, alongside existing backers General Catalyst and Insight Partners.
The money buys wargames. Onebrief used it to acquire Battle Road Digital, a defence innovation company that applies gaming technology to defence and national security. Battle Road’s AtomEngine wargaming simulation brings real-time operational decision support into Onebrief’s platform, which calls itself the operating system for modern command. Chief executive Grant Demaree talks of building a “superhuman military command”.
The proceeds will also expand Onebrief’s AI Assist and its wartime resiliency work. Battle Road, founded in 2021, had raised a $5 million seed round. Defence tech drew a record $7.7 billion of venture investment in 2025, and Onebrief is now its newest unicorn with a war chest.
See, simulate, and decide faster than ever before: that is the pitch. The generals get a dashboard; the gamers get a defence contract.
Conclusion: Onebrief is not a planning tool, but rather a command operating system — and war games are now a line item on a cap table.
