Zavu

Zavu is a unified messaging API built for modern AI-driven applications and communication SaaS. It provides a single developer-friendly interface to send and manage messages across WhatsApp, SMS, and Email, without the operational complexity of traditional CPaaS platforms.

Traditional CPaaS solutions were designed for human-driven messaging and per-message pricing. That model breaks down for AI apps, where conversations are generated, routed, retried, and managed automatically by agents and workflows. Zavu was rebuilt from the ground up to support these AI-first patterns with predictable pricing and simpler abstractions.

The platform includes built-in phone number provisioning, removing the need to source, configure, or manage numbers from external providers. Developers can get an API key, provision numbers, and send their first message in minutes. Routing, failover, and delivery are handled at the infrastructure level.

Zavu uses a pricing model aligned with how AI apps operate, combining MAU-based usage with transparent carrier costs. This makes messaging costs easier to understand, forecast, and scale, even when agents generate multiple messages per interaction.

From a developer experience perspective, Zavu focuses on modern SDKs, clean primitives, and clear documentation. Complex and fragmented APIs, especially around WhatsApp, are abstracted behind a simpler interface so teams can focus on building AI workflows instead of dealing with provider-specific quirks.

Zavu is designed for developers building AI agents, automation platforms, and modern communication products who need reliable messaging infrastructure without vendor sprawl, hidden fees, or legacy CPaaS constraints.
