CMBBuilt at CMBYTES
Products we build for ourselves.
Client work shows us the same gaps again and again. When a gap is big enough, we build the product ourselves — and run it with the same standards we bring to client systems.
Kolo
Group savings, run like clockwork.
Kolo brings the njangi — the rotating savings group millions of Cameroonians already trust — onto a shared ledger. Contributions, payout order, penalties and meeting notes are reconciled against mobile money, so the treasurer's notebook becomes a record every member can see.
- Contributions collected through MTN MoMo and Orange Money
- Transparent payout rotation, penalties and loans
- SMS access for members without smartphones
Lumo
An AI study partner for exam candidates.
Lumo helps secondary students prepare for the GCE and BEPC with practice questions aligned to the national syllabuses, explanations in French and English, and a study plan that adapts to what each student gets wrong.
- Syllabus-aligned practice in French and English
- Step-by-step explanations reviewed by teachers
- Works on low-cost Android phones and patchy data
Tamtam
One API for SMS, WhatsApp and USSD.
Tamtam is messaging infrastructure for products built in Africa. Send transactional messages across SMS and WhatsApp with automatic fallback, run USSD sessions defined as code, and get one honest delivery report per message.
- Channel fallback from WhatsApp to SMS
- Versioned bilingual templates
- Idempotent requests and normalised delivery reports
Ndop
A design system for products built in Africa.
Named after the indigo ndop cloth of the Grassfields, Ndop is an open-source design system with components for mobile money flows, bilingual forms, low-bandwidth imagery and offline states — patterns we kept designing from scratch.
- Mobile money and offline-state components
- French and English content guidelines
- Open source, framework-agnostic tokens
