About Zavu Labs Inc
Zavu is a communication platform that puts WhatsApp, SMS, voice, email, phone numbers, Telegram, Instagram and Messenger behind one API, one webhook and one bill. Teams can deploy on Zavu's infrastructure or call the API from their own, starting with one channel and enabling others without rewriting existing code. Meta's WhatsApp charges are passed through at cost, while SMS and calls are priced per destination.
The product is built to be set up by coding agents: skills install into Claude Code, Cursor, Codex and other agents, alongside a CLI and an MCP server that exposes every endpoint. Developers can define AI agents and deterministic workflows in TypeScript that answer customers across channels, draw on a knowledge base, call tools, keep memory per contact and answer phone calls as voice agents. Models from OpenAI, Anthropic, Google or Mistral can be used with a customer's own key.
Common uses include transactional notifications, OTP codes, broadcasts, shared inboxes and multi-tenant setups for agencies. SDKs cover TypeScript, Python, Ruby, Go and PHP, with integrations for GitHub, Vercel, Supabase, n8n and WordPress/WooCommerce.
