Powering messaging for startups and scale-ups globally
The Problem
You're here to build products, not messaging infra.
Too many APIs to maintain
Twilio for SMS, Meta API for WhatsApp, SES for Email — each with different SDKs, auth models, and error handling. You're maintaining three integrations instead of shipping features.
Integration takes weeks, not minutes
Phone numbers, webhooks, template approvals, sender verification — by the time you've set everything up, the sprint is over. Messaging shouldn't be a project.
WhatsApp is a project in itself
24-hour windows, WABA setup, Meta Business verification, template approvals — just sending a WhatsApp notification requires more compliance work than your entire auth system.
Costs are unpredictable and growing
Per-message pricing on every channel, no visibility into which route is cheapest. Smart routing could save you 80% but you'd have to build it yourself.

Smart routing savings
ML picks the cheapest channel per message using delivery intelligence aggregated across the entire platform. This routing improves as the network grows — decisions that would be impossible with isolated data.
100%
Unified observability
Delivery receipts, cost tracking, latency metrics. Every message, every channel, one view.
Smart fallback, zero code
When WhatsApp fails, Zavu automatically falls back to SMS. No retry logic in your code. Context is preserved, delivery is deduplicated, and cost is tracked end-to-end across the fallback chain.

We're the only messaging platform that gives direct human support to ALL customers — not just enterprise. No tiers. No ticket queues. Real engineers, real answers. Migrating from another platform? We'll help.
