Zernio

Your marketing isn't fragmented. It's a custody battle across 16 apps.

Zernio ends the drama with a single API for posting, messaging, analytics, and ads. Ship a post, send a DM, pull a report, or launch a campaign in minutes, not sprints.

Developers get SDKs in JavaScript, Python, Ruby, Java, PHP, and .NET, plus a REST API, CLI, and an MCP server for AI agents. From signup to first post or ad in under five minutes is standard, not a miracle. Automation like publishNow cuts lag so your content and replies go out on time, every time.

Run a unified inbox for voice, SMS, and WhatsApp on one number with shared billing. Reply faster, route smarter, and stop losing customers in DMs. The Ads API brings Meta, Google, LinkedIn, TikTok, Pinterest, X, Bluesky, and OpenAI Ads into one place so budgets, creatives, and ROAS live side by side.

At scale, Zernio stays boring where it should: SSO, MFA, SCIM, RBAC, audit logs, SOC 2, and 99.97% uptime. Pricing starts free for two accounts and shifts to usage based as you grow, so startups move now and agencies don't stall later.

For online business owners, this means fewer tabs, fewer tools, and fewer missed messages. Your team spends less time duct taping channels and more time driving sales.
