“From joint integration to allied collaboration, agile engineering, and automation, the future of U.S. defense depends on our ability to virtually test, train, and iterate at scale.”

Robbie RobertsonSedaro CEO & Co-founder

We deliver connected simulation infrastructure that empowers humanity
to create, predict, and decide with confidence.

01 — WHAT WE DELIVER

We build the digital engineering and simulation layer underpinning critical national security missions.

02 — Why it matters

The systems of tomorrow are too complex, too interconnected, and too expensive to build without rigorous simulation.

03 — WHERE WE'RE HEADED

National security is where we focus today, but our approach extends to other domains and markets.

Built differently, by design.

Our agile, incremental software approach enables collaborative and continuous progress
