Built by an Engineer, for Engineers
The story behind Hassab and its mission to empower Gulf engineers.
Ahmed Rabaiah
Electrical Engineer & Software Developer
As an electrical engineer working in Saudi Arabia, I experienced firsthand the pain of scattered calculation tools, outdated spreadsheets, and the lack of region-specific engineering software. Hassab was born from the need for a unified, modern, and standards-compliant toolkit that speaks the language of Gulf engineers, literally.
Our Mission
Why we built Hassab
Hassab is and will always be free for individual engineers. We believe every engineer in the Gulf region deserves access to professional-grade tools without financial barriers. Our vision is to build the most comprehensive electrical engineering platform tailored for the Middle East market.
