Our Platform

OmniHub — Multi-channel messaging,
one dashboard and one API.

OmniHub is Paradox Interactive Ltd's multi-tenant communications platform. Banks, fintechs, telcos and enterprises across Africa use it to send WhatsApp, SMS, USSD and voice messages — and to collect M-Pesa payments — through a single web dashboard and a unified REST API. Each customer connects their own WhatsApp Business Account, manages their own templates and senders, and accesses only their own data through their own login and API key.

Resellers run sub-accounts and per-tenant pricing schemes. Enterprises rely on the unified inbox, approval workflows and audit log to keep their compliance posture clean. Developers integrate through one REST API instead of one per carrier.
