The Series C round was led by General Catalyst and Insight Partners, with participation from Caffeinated Capital, 9Yards Capital, and Human Capital. Human Capital also led Onebrief’s Series B round in 2024. Each investor was selected for their deep expertise in global defense markets and commitment to accelerating Onebrief’s mission.

“At General Catalyst, our mission is to help modernize our nation’s defense and industrial resilience. At the core of this resiliency is our military’s ability to make rapid operational decisions in distributed and dynamic environments. We met Grant Demaree and Onebrief over two years ago and were struck by the clarity of their approach. My partners, Lt. Gen. USAF (Ret) Scott Howell and Matt Byington have experienced the military planning process firsthand and quickly noticed the advantages that Onebrief provides at every echelon. We’re excited to partner with Onebrief and help them support warfighters and military staffs to be more efficient and effective in their profession,” said Paul Kwan, Managing Director, General Catalyst.

“At Insight Partners, we are committed to supporting companies that will create lasting impact in the sectors they serve, and Onebrief is a prime example,” said Nick Sinai, Managing Director at Insight Partners. “Their approach to operational planning lays a foundation for transforming military decision-making. Innovation in defense technology is critical for ensuring global stability and security, and Onebrief’s platform can help redefine what is possible.”

Onebrief’s Series C follows a year of consequential growth. Today, the platform is used across U.S. military headquarters worldwide to accelerate planning, provide faster command decisions, and help staffs work efficiently. As a result, Onebrief is now integral to three of the four largest operational plans (OPLANs) globally and is used for even more day-to-day operational plans. With its latest funding, Onebrief will continue that momentum by advancing the platform, expanding teams, and investing in customer development.

Company Growth

Following nearly 130% employee growth year-over-year, the company will continue to expand its product, customer success, and growth teams. This funding has also enabled Onebrief to make significant leadership appointments.

Chris C. Miller, former Acting Secretary of Defense, has agreed to join Onebrief’s Board of Directors. Miller brings 34 years of service in the Army and national security apparatus of the United States. His service culminated as the Acting Secretary of Defense where he successfully led its nearly three million service members and civilian employees. Currently, he is a business strategist and advisor within the defense industry, and the author of Soldier-Secretary: Warnings from the Battlefield & the Pentagon about America’s Most Dangerous Enemies.

“Onebrief is the capability I dreamed of in my early military career, and as a senior civilian official, it’s the tool I wanted to provide our fielded forces and supporting staff to ease their planning and wargaming burdens — work that ultimately determines who lives and dies, and what force wins or loses,” said Miller. “I’m proud to be part of Onebrief’s mission. I have said many times that the genius of America is the vibrancy of our free-market system and the talent of our entrepreneurs and brilliant technologists.”

Lieutenant General (Ret) Lewis Craparotta, USMC, has agreed to join Onebrief’s Board of Directors, having served as a Senior Advisor to Onebrief since 2021. In his military career, Craparotta commanded in the operating forces at every level, notably in Marine Forces Pacific and I Marine Expeditionary Force. He also served on the Joint Staff, at Special Operations Command Europe, and as the Director of Operations at U.S. Northern Command.

“Over the past three years I have been amazed by the vision, drive, and growth of this company as we continuously refined the platform for our customers,” noted Craparotta. “We have a novel opportunity to enable true global collaboration and integration. There is also the potential for application beyond our current scope, and I’m looking forward to continuing this important work.”

Devesh Senapati joins as the new Vice President of Product. Most recently, he served as Product Lead at Stripe, a leading financial infrastructure platform, where he led the development of Terminal, Stripe’s in-person payments product suite. Prior, Senapati worked across multiple early-stage startups and as a software investor at Bain Capital Ventures. He began his career as a consultant at McKinsey & Company. Senapati earned his MBA from Stanford Graduate School of Business and BBA from the University of Michigan’s Ross School of Business.

This raise is also a milestone event for early employees as Onebrief has executed a Tender Offer, allowing them to sell shares on the secondary market. The company aims to ensure employees benefit from the new funding.

Platform and Mission Alignment

Strategic developments within the core platform enable Onebrief to support the evolving and complex needs of tomorrow’s military staffs. These advancements include improvements in deployment solutions, delivering reliable and performant networks; impactful new features, like offline capabilities or an AI Co-planner; and longer-term development of AI-driven wargaming for course-of-action (COA) development. These developments can help redefine military decision-making.

By transforming operational planning and workflows, the opportunity to make a stronger impact with fewer resources becomes a reality. This vision aligns with the new administration’s focus on the implementation of AI to reduce resources and government spending.

“Simply put, transforming operational planning will win the war. This funding and our new partnerships unlock the ability to drive real, powerful change across our institutions,” said Grant Demaree, CEO of Onebrief.
