ABOUT HESABU

Financial clarity shouldn't require a finance degree.

Hesabu is my attempt to simplify everyday financial decisions through useful software and intelligent digital tools designed for real-world use in Kenya.

What I'm building toward

Hesabu explores how software can make financial systems more understandable, accessible and practical for everyday users. The goal isn't just to build calculators, it's to remove the friction between people and the financial information that affects their daily lives.

Why Hesabu?

Financial systems in Kenya are often confusing, fragmented and difficult to navigate. Understanding M-Pesa charges means scrolling a 4-page PDF. Understanding your salary means decoding a payslip nobody explained to you. Knowing whether Fuliza is worth it means doing mental math on the spot.

Hesabu removes that friction. Enter a number, get a clear answer. No PDFs, no confusion, no finance degree required.

Turning complex systems into simple usable software.
