Stell was founded in 2022 with a simple premise: the software running defense and aerospace programs hadn't kept pace with the programs themselves.

Requirements were managed in documents. Traceability lived in spreadsheets. Audit prep was weeks of manual work. And the tools purpose-built for the problem were designed before modern cloud infrastructure existed.

Stell's team includes systems engineers who have worked inside these programs - people who know what a compliance matrix review actually looks like, and what it costs when traceability breaks. That domain knowledge shapes every product decision we make.

Today Stell is deployed on U.S. Space Force and Air Force programs, and used by commercial aerospace and defense contractors across the industry.
