View company profile

Onebrief makes military planning fast and collaborative. This type of planning is characterized by creative problem solving and high-stakes decision making, but currently it's unacceptably slow. Among U.S., NATO and allied countries, there are thousands of units where Onebrief is sorely needed now. As one of our customers said, “if we had Onebrief in 2001, Afghanistan would be in different shape today.” In 5 years, it will be unthinkable to present military options to the President in anything but Onebrief.

We are on track to be one of the first defense companies built in the model of modern SaaS startups to deliver a consumer grade user experience with real impact.

We are post-revenue and backed by a mix of Silicon Valley venture capital and former military officers. We’re also an AFWERX (US Air Force) SBIR awardee.

We are based in Austin/TX but operate as an all-remote company.
