The moment:

Everyone uses AI. Few get ahead with it.

Almost every company now uses AI, but very few turn it into results. In marketing, the blocker isn't the technology. It's people: teams worry about being replaced, and most lack the skills to build with AI. Agents designed around your team close that gap.

See What We've Built
Our point of view:

HumanAI: human to the power of AI.

Human × AI is multiplication. Humanᴬᴵ is exponential.

Most AI systems aim to replace tasks. Humanᴬᴵ aims to elevate thinking. We build AI as a collaborator that amplifies your team's judgment, inspired by MIT professor Thomas W. Malone's idea of Superminds: humans and machines thinking together.

That answers the real blocker: 80% of CMOs say staff fear and anxiety block AI experimentation (Gartner, May 2026). We don't sell automation. We amplify your people.

The machine brings scale. Your team brings meaning, taste and direction.

Plug and play vs built for you:

Not another AI tool. An agent built for you.

Plug and play AI tools give every company the same features, so they produce the same work. A custom agent starts from your brand, your problem and the result you need, and fits the way your team already works. That's the difference between using AI and getting ahead with it.

Cases:

Two problems. Two agents that solved them.

We don't start from an agent. We start from a problem a marketing team couldn't solve with the tools it had, then build the agent that solves it. Here are two.

Case: one of the world's largest vacation rental platforms

Story Scout: true customer stories, ready to become ads.

The problem
Their guest reviews held amazing stories, but they were hard to find.
What we built
Story Scout, an agent that reads guest reviews, pulls out the true stories with a plot, sorts them by theme and suggests how to turn each one into an ad. It runs on a schedule for the search terms the team tracks, or on demand for one-off searches. We capped the first edition at 40 stories and discarded one, leaving 39, every one rated 10/10 or the five-star equivalent.

Hours
The result
For the first time, the rich content in their guest reviews is within reach and actionable.
Story Scout's first edition: 39 positive true stories, filtered by theme, each card with its adaptation angle

  • Adventure

    The Bear at the Hot Tub

    Feel-good adventure comedy: a lifelong bear-watcher's dream comes true when a black bear ambles past the hot tub, and she gets it all on video.

  • Wedding

    The Wedding They Never Got in 2020

    Romantic drama: a couple robbed of their wedding by 2020 finally gets their celebration, years late and more meaningful than ever.

  • Host kindness

    The Mailed Stuffed Animal

    Heartwarming family comedy: a little girl's vacation is rescued when the host mails her forgotten stuffed animal home like a special mission.

Three of the 39, lightly edited from the agent's output to remove identifying details.

Case: Bizee

Lead Magnet Agent: offers people actually sign up for.

The problem
Bizee had been making lead magnets with generic AI prompts, and wanted a real system for it.
What we built
A Lead Magnet Agent that comes up with lead magnets made for Bizee's customers, in formats people actually use (quizzes, calculators, template packs, audio series), each with its hook and call to action. It shipped with the Meta campaign to promote them.

Beyond these two:

Other agents we've built.

Every client brings a different problem, so most of our agents are one of a kind. Four more, and what each one opened up:

  • Advertising Legacy

    Reads years of a brand's past ads, frame by frame and line by line.

    The gain The team could finally see how the brand has talked to its audience over time, in words and visually, and set that history against brand tracking and sales to see what moved the needle and what to carry forward.

  • Audience clustering

    Machine learning models cluster a brand's customers from research and first-party data, then turn each cluster into a profile the creative team can work with.

    The gain Segments the brand wasn't seeing, new creative possibilities for each one, and a sharper way to reach more people like its best customers in paid media.

  • Creator casting

    Searches social platforms for creators who fit a brief, checks each one's audience and fit, and scores a shortlist.

    The gain Brands find the right creators across the open web, without the trap of a closed marketplace and its short list of names.

  • Multi-source analysis over time

    Follows all of a client's data sources together, from campaign results to brand tracking and sales, and reads how they move over time.

    The gain Suggestions across the board, connecting a change in one source with what happened in another, instead of one report per channel.

If your problem sounds like one of these, or like nothing on this page, tell us about it.

How we work with your team:

We join your team and build what it needs.

Gravta works inside your in-house creative and marketing team. We listen for the "we wish we could…" moments, then build whatever unlocks them: agents, workflows, software or creative. Your team learns by building with us. Not consulting decks, not a tool license: shipped capabilities.

Meet

Find the friction

A standing session with your team to surface what slows it down and what it wishes it could do.

Teach

Build the skills

Hands-on sessions and playbooks, so your team runs what we build.

Build

Ship it

The agent, workflow, software or creative, usually in days, not quarters.

Everything we build fits the way your team works, and it's yours.

Free or connected:

Your agents can run free or integrated with your marketing intelligence data through AdNeura, a proprietary AI Hub developed by Gravta.

Start With Your Use Case
Before you ask:

"But…"

  • "We already have ChatGPT."

    Great for one-off questions. An agent is different: it's built for one job and one brand, follows the same steps every time, and returns finished work in your team's format.

  • "We don't know what we'd build."

    That's normal. We start by listening for the "we wish we could" moments, and find the first agent together.

  • "Our team isn't technical."

    It doesn't need to be. We build the agents and teach your marketers to run them. They stay in charge of the work.

  • "Isn't this just a plug-in?"

    No. A plug-in is the same for everyone. We design each agent for your use case, with creative and engineering working together.

FAQ:

AI marketing agents, answered.

What is an AI marketing agent?

An AI marketing agent is software that carries out a marketing task on its own, step by step: reading sources, making decisions and producing finished work. Gravta builds each agent for one team's problem, and the team stays in charge.

How is a custom AI agent different from ChatGPT?

ChatGPT is a general assistant that starts from a blank prompt every time. A custom agent is built for one job and one brand: it follows the same steps every time and returns finished work in the format your team uses.

What problems can a custom agent solve?

Whatever your team keeps saying "we wish we could" about. We've built agents that find true customer stories hidden in reviews and that come up with lead magnets people sign up for. Revenue gains from AI are most often attributed to marketing and sales (McKinsey).

How long does it take to build an agent?

Days, not quarters. Story Scout was built in hours. The Lead Magnet Agent for Bizee was built and shipped in two days, together with the Meta campaign.

Do we need a technical team?

No. We build the agents and teach your team to run them in hands-on sessions. Your marketers stay in charge of the work.

Who owns the agents and the work?

You do. Everything we build for you is yours.

What is a customer story agent?

An agent that reads customer reviews, finds the true stories with a plot, sorts them by theme and suggests how to turn each one into an ad. Gravta's Story Scout does this for one of the world's largest vacation rental platforms.

What is a lead magnet?

Something useful people get for free in exchange for their email: a quiz, a calculator, a template pack, an audio series. A lead magnet agent comes up with them for your brand, each with a hook and a call to action.

Can you build an agent for a problem that isn't on this page?

Yes. That's most of what we do. Every client brings a different problem, so most of our agents are one of a kind.

What is Humanᴬᴵ?

Humanᴬᴵ, or human to the power of AI, is Gravta's point of view: AI as a collaborator that amplifies human judgment, not a tool that replaces it. Read Duda Guerra's article.

How does working with Gravta work?

Gravta joins your in-house creative and marketing team. We meet regularly to find what the team wishes it could do, build it, and teach the team to run it.

Let's talk:

What does your team wish it could do?

Tell us, and we'll show you the agent we'd build for it.

By 2028, 60% of brands will use agentic AI for one-to-one interactions (Gartner, Jan 2026).
