What our clients say.
A product company that also builds for clients.
Fanisi is Swahili for success and prosperity. We started in Dar es Salaam in 2023 believing the best way to build software for East African businesses is to run some of our own.
Running Tenga, Knotly and E-Chapa teaches us what works here: slow connections, Swahili and English, and customers who would rather send a WhatsApp than fill in a form. Our clients get software built on that experience.

Translation isn’t a feature you add at the end. It decides who can use the product at all.
