On-premises WhatsApp marketing for regulated enterprises — 50M+ messages, 99.9% delivery.
challenge
Finance and healthcare enterprises require absolute data sovereignty. Existing WhatsApp marketing tools are SaaS-only — unacceptable PII risk for regulated workloads where the customer's data can never leave the bank.
approach
We engineered an enterprise-grade, fully on-premises WhatsApp campaign platform. It integrates with internal CRM via the WhatsApp Business API and ships with audience segmentation, template management, and analytics. 100% of data stays inside the client's firewall.
outcomes
50M+ messages processed at 99.9% delivery. 12 enterprise deployments live in production behind customer firewalls.
