Onebrief: $20 Million Series C Extension Raised For Military Staff Software Platform

By Amit Chowdhry • Yesterday at 11:00 PM

Onebrief, a leading software for military staff collaboration and operational planning, announced a $20 million Series C extension led by Battery Ventures. This funding round scales the company’s valuation to $1.1 billion, an increase from the $650 million valuation achieved three months prior in Onebrief’s Series C funding round.

This deal marks a significant milestone for Onebrief. This growth comes at a time when the U.S. Department of Defense (DoD) is accelerating and prioritizing the need for commercial off-the-shelf software to transform and support the warfighter.

Onebrief transforms military collaboration from a fragmented and manual process into an integrated and intelligent workspace. Before Onebrief, military staff work was slow, inefficient, and resource-intensive due to the use of legacy tools. Staff would spend weeks or months building tens of thousands of slides. This process would be conducted without version control or a means to coordinate across commands in real-time.

This deal reinforces Onebrief’s leadership in a growing defense tech market. The platform is aligned with the federal government’s modernization priorities, optimizing military staff and potentially unlocking over $100 billion in savings across the Future Years Defense Program. And as one of the fastest-growing defense tech startups in the U.S., with user hours growing at a 19,600% annualized rate, Onebrief is quickly becoming the platform of choice for planning across the Department of Defense.

How the funding will be used: Onebrief plans to use the funding to accelerate its engineering and expand its infrastructure to support allied and joint operations worldwide. These advancements will help drive broader utilization and readiness for potential future conflicts, with the ability to support 100,000 simultaneous collaborators and remain operational under adversarial conditions.

Onebrief will also focus on advancing AI and integration capabilities to enhance decision-making. Users now report a 2x increase in efficiency and productivity when using the platform. This funding and focus on AI development will help Onebrief scale user productivity by 100 times within the next three years.

KEY QUOTES:

“Becoming the newest unicorn in a small group for defense tech is an incredible milestone. This new funding enables us to deepen our investments in wartime resilience, reach, and artificial intelligence (AI), so our platform can keep pace with the demands of modern conflict. Battery Ventures is the ideal partner to help us realize that vision. We’re pleased to partner with them, leveraging their experience in defense tech as we progress toward this next phase.”

“Our mission is to make the military staff smaller, smarter, and faster. Now, we’re one step closer to making that vision a reality.”

Onebrief CEO Grant Demaree

“We were drawn to Onebrief’s experienced team and the company’s powerful vision. Onebrief’s technology consolidates several key elements of war planning into one platform. It’s an intuitive model that has been organically adopted in a viral, bottom-up manner in many corners of the U.S. military, including four of the seven geographic combatant commands and other important units in the critical Indo-Pacific region. We’re excited to see Onebrief continue to expand its reach and help the DoD deliver on its stated agenda of operating faster, more efficiently, and cost-effectively.”
