About Qitab

Qitab was built by a systems engineer who worked on large engineering programs and couldn't find a tool that worked.

Its founder, Sami Dahoux, started his career in the railway sector where he experienced first-hand the cost of fragmented specifications, vendor lock-in, and the gap between requirements documents and the systems they were meant to describe.

In 2021, he designed the req language, bringing the plain-text, git-native workflow of modern software engineering to systems specifications. Qitab is the editor built on top of it.
