1. Data Sovereignty & Zero Third-Party DB Access
In traditional multi-tenant WhatsApp SaaS platforms (WATI, Respond.io, SleekFlow), all customer phone numbers, chat logs, and PII live on shared third-party databases.
Klaros deploys directly to your own Cloudflare account. Your data stays in your Cloudflare D1 database and R2 bucket, completely isolated with zero vendor access.
