Bootstrapped. 9 people. $5M ARR.

No investors, no office. A small remote team around Barcelona, funded only by our customers.

Not a scheduler. The primitives a GTM agent is made of.

Every agent built on Zernio is the same loop. Something happens, the agent reads what it needs, then it acts. Zernio gives you each piece as an API call, on every network.

Your agent wakes up when something happens.

Webhooks, so you never poll. Each one is a reason for an agent to exist.

Real use cases, far beyond auto-posting.

Build the agent a team would hire, not a scheduler.

Three ways in. Pick the one your team already uses.

Don't let your AI guess. Give it the docs.

Get one post out, then build the clever part.

import Zernio from "@zernio/node";

const zernio = new Zernio();
// uses ZERNIO_API_KEY

await zernio.posts.createPost({
  body: {
    content: "Hello Paris!",
    platforms: [{
      platform: "linkedin",
      accountId: "acc_123",
    }],
    publishNow: true,
  },
});
