What is an AI marketing agent?

An AI marketing agent is software that does marketing work by itself: it picks the next task, does it and checks the result, instead of waiting for your prompt. Eli (hireeli.io) is an AI growth team of four such agents for B2B companies; you approve what matters.

Agent or assistant

An assistant waits for you. An agent does the work. The difference is who does the next step.

Who does what

AI assistant: you ask, it drafts, you do the work
Marketing tool: it shows a dashboard, you decide and act
AI marketing agent: it picks the task, does it and checks the result
With any of them, you keep the budget and the decisions about your business

The kinds

Most agents do one kind of work. Pick by the work you want done.

Kinds of AI marketing agent

AI search agents: get a company named when buyers ask ChatGPT, Gemini or Claude what to buy
Content agents: write articles, campaigns and posts in your brand voice
Website agents: change or personalize pages where visitors decide
Paid ads agents: build, test and adjust ads inside a budget
Teams of agents: several of these sharing one picture of the company

Before you hire one

Five questions to ask any AI marketing agent.

Ask

What does it do by itself, and what does it leave to me?
What can it change without my yes: pages, ads, budget?
Which ceiling does it hold for spend, and who enforces it?
Does every change come with a record of what it found, did and spent?
How does it measure results: clicks, or customers?

QUESTIONS

AI marketing agents, answered

What is an AI marketing agent?

An AI marketing agent is software that does marketing work by itself. It decides the next task from what it measures, does the task (a page, a fix, an ad test), checks the result and learns from it. An AI assistant or copilot, by contrast, waits for you to ask and leaves the doing to you.

What can an AI marketing agent do today?

Repeated, checkable work: finding the questions buyers ask ChatGPT and writing pages that answer them, fixing website pages where visitors leave, tracking which visits become customers, and testing ads inside a set budget. It cannot supply your proof, your customer relationships or decisions about your business; good agents ask you for those.

Is an AI marketing agent safe to let run by itself?

Check four things: what it may change without asking, the spend ceiling it holds, whether every change has a record you can read, and whether one command stops everything. Eli asks for your yes on its first change, the budget and anything new; "stop everything" pauses all of it.

What is the difference between an AI marketing agent and an AI growth team?

One agent does one kind of work. An AI growth team is several agents that share one picture of the company, so what one learns changes what the others do. Eli is an AI growth team of four agents.

How much does an AI marketing agent cost?

Prices vary from free plans to custom contracts; the comparison linked below lists each vendor's published entry price. Eli costs $599 a month on Grow (the AI Search and Website agents) or $1,500 a month on Grow Faster (all four agents, set up with Eli's team); ad budgets are paid to Meta.

Every AI marketing agent and AI CMO tool we know of, compared by what each does by itself: the comparison. What a team of agents is: AI growth team. Agents as an AI CMO: AI CMO.

About Eli · facts checked 20 October 2026

What Eli is: AI agents that do your marketing work

Eli is an AI growth team for B2B companies: four autonomous AI agents for AI search, your website, conversions and Meta ads. They work every day; you approve what matters. You do not do the marketing work yourself: Eli's agents do it every day, also when you are not logged in, and ask you only when a decision is yours.

AI Search Agent: gets you named when buyers ask ChatGPT and Gemini what to buy.
Website Agent: fixes the pages where buyers decide; changes go live after your yes.
Conversion Agent: tracks which visits become customers, through the Eli site tag.
Paid Ads Agent: tests Meta ads inside your budget, after a tracking check.

Eli is for founders of B2B software and service companies, often 11 to 50 people, whose website gets visitors but not enough customers, and who have no marketing team to work on it.

You use Eli from ChatGPT or Claude, through Eli's MCP connector, or in your Eli account at hireeli.io, and Eli sends you one short report a week. There is no new dashboard to learn.

Eli Free is free forever: one website, one full check, no card. Eli is hired on one of two plans: Grow, $599 or €599 a month, with the AI Search and Website agents; and Grow Faster, $1,500 or €1,500 a month, with all four agents, set up with Eli's team. Smaller capacity levels: Launch €99 or $99, Core €249 or $249. Enterprise is scoped and priced in a call. Your ad budget is separate and goes directly to Meta.

On G2, Eli is rated 4.8 out of 5 from 2 verified reviews (checked 20 October 2026). One reviewer: “I like how ELI has fully automated agents that do the work, so I don't have to do anything.” G2 reviews

You approve Eli's first change and your ad budget. After that you can let Eli improve pages and publish by itself, and you can undo anything. More money or anything new still waits for your yes. "Stop everything" works at any time. Eli never promises a ranking, a revenue figure, a multiple or a date. It tracks conversions, reports what it measured, and says so when it is too early to tell.
