Zero Human is a developer-first customer messaging platform. Instrument your product with a typed SDK, connect MCP in your IDE, and ship lifecycle flows without leaving your editor.
What you can build
Event ingestion
Signups, trials, purchases, and custom events with Zod-validated schemas.
Segments & RFM
Lifecycle cohorts from the same customer graph your agents read.
Flows
Activation drips, win-back branches, WhatsApp and email from one builder.
MCP control
Describe campaigns in plain English — your agent reads live events and segments.
Getting started path
Work through the three guides in order:
- Connect MCP — OAuth once in Cursor or Claude Code.
- Send events with the SDK — server-side secret keys and browser publishable keys.
- Ship flows — turn events into lifecycle messaging.
