Zernio is marketing infrastructure for products and agents: one API for social, ads, messaging and calls.
Instead of building an integration for every channel, each with its own API, auth and review process, you integrate once, on official platform APIs, and most teams launch the same day.
Social, ads, unified inbox, SMS, RCS, iMessage, WhatsApp, calls and numbers in 57 countries. A hosted MCP server lets agents connect accounts, run campaigns, send messages and place calls on their own.
