Build. Automate. Grow.
DevMall builds and sells its own software: web platforms, SaaS tools and ready-to-deploy source code with AI built in, for fintech companies and businesses that want to be online and working faster. Every product ships with a clear licence, documentation, a live demo and support from the team that wrote it.
32 products across 6 categories, each with a licence, documentation and a hosted demo
Platforms and tools we are proudest of: documented, demoable, in production with customers.

We sell what we build and support what we sell. Four things are true of every product in the catalogue.
Document and ID extraction, transaction classification, risk scoring, support assistants. Built into the product, explainable, and switchable off.
M-Pesa and card payments, double-entry ledgers, audit trails, consent and data-protection controls that satisfy the Kenya DPA and GDPR.
Every product has a hosted demo you can open now, and a guided walkthrough with an engineer when you want one.
Clear licences, versioned releases, and a support window answered by the people who wrote the code. Custom work when you need it.
The products customers have bought and put into production the most.
