Re-imagining How Businesses Connect on WhatsApp
Sandesh was built to replace personal phone workarounds and fragile scripts with a robust, multi-tenant software workspace engineered for clarity and dependability.
The Sandesh Story
WhatsApp is the world's most direct communication medium. Yet for most growing businesses, managing it remains fraught with problems: customer conversations trapped on personal smartphones, zero delivery visibility, manual copy-pasting of templates, and nonexistent API integration.
We built Sandesh to bridge this gap. By uniting instant multi-device QR authentication, contact segmentation, campaign management, event automations, and developer webhooks under a single workspace, teams can collaborate seamlessly while preserving complete auditability.
Our Core Architectural Principles
How we approach security, deliverability, and developer experience.
Multi-Tenant Data Isolation
Every organization functions inside an isolated tenant container. Contacts, sessions, credentials, and message histories never intermingle.
High Throughput, Zero Gimmicks
We focus on core messaging reliability, decoupled queue workers, and verifiable status tracking rather than superficial buzzwords.
Account Safety & Rate Limiting
Our system enforces intelligent dispatch throttling and humanized delays to safeguard phone number health and prevent anti-spam triggers.
Developer-First Transparency
Clean REST endpoints, HMAC-signed webhooks, and predictable JSON structures empower teams to embed WhatsApp directly into internal software.
