Thecalcs began as a personal experiment by Souhayb Kamal, a full-stack developer, to make technical calculators more usable and beautiful.

What started with a few math and finance tools grew into a full SaaS-style calculator library — now trusted by thousands of users and used by companies worldwide to develop custom tools for their own websites.
