The problem

Wiring WhatsApp into a product is rarely one integration. Sessions drop and have to be re-paired by hand, one account is never enough once a business has several brands or regions, and the per-message fees most resellers add turn a messaging feature into a line item that grows with success.

The solution

A hosted platform that keeps sessions alive, routes across several at once, and delivers every inbound event by webhook so the calling application stays in sync. Message content is never stored, each tenant runs in its own sandbox, and pacing is managed to protect the number. Pricing is for the platform, not per message.

Our role

Our own product. App Genesis designed, built, hosts and supports it — the session layer, the routing, the webhook delivery and the billing.
