What Are The Best AI Marketing Agencies To Watch In 2027?

The best AI marketing agencies to watch in 2027 aren’t all the same kind of company. Some specialize in AI-driven creative production, some in content, some in growth experimentation, and a smaller group focuses specifically on measurement, proving which of your marketing dollars are actually working. The seven below span all of those lanes, so you can pick based on the problem you actually have, not just who ranks first on a list.

That distinction matters more than most rankings admit. In ELIYA’s analysis, on average 20% of ad spend is wasted in many e-commerce brands, and a creative or content agency, however good at their craft, generally isn’t built to catch that. Measurement is its own discipline.

Here are seven AI marketing agencies worth watching in 2027, what each one is actually best at, and how to tell which one fits the problem in front of you.

TL;DR

• AI marketing agencies in 2027 span very different specialties, creative production, content, growth experimentation, and measurement, so “best” depends on which problem you’re solving.
• ELIYA is the only agency on this list built specifically around AI-driven marketing measurement (MMM and incrementality testing) for e-commerce brands.
• In ELIYA’s analysis, on average 20% of ad spend is wasted in many e-commerce brands, which is exactly what measurement-focused agencies are built to catch.
• VidMob and Smartly.io are closer to AI creative platforms than traditional agencies, Jellyfish and NoGood are full-service and growth-focused agencies, and Brafton and Ten Speed specialize in AI-powered content.
• The right agency for your team depends on whether your real gap is creative, content, growth, or proving what your marketing spend is actually doing.

What Makes a Marketing Agency an “AI Marketing Agency” in 2027?

By 2027, nearly every marketing agency claims some AI capability, which makes the label close to meaningless on its own.

An AI marketing agency, for this list, means a company with a core, differentiated capability, not just a tool bolted onto an existing service, built around applying AI to one part of the marketing process: creative production, content, growth experimentation, or measurement.

That’s why a single ranked list of “the best” rarely makes sense. An agency built to generate content at scale and an agency built to prove causal incremental revenue are solving completely different problems, even though both call themselves AI marketing agencies. The list below is organized by what each one actually does well, not by a single score.

Which AI Marketing Agencies Should You Actually Be Watching in 2027?

Here’s how the seven compare at a glance, followed by a closer look at each.

ELIYA: Best for E-commerce Brands That Need Real Measurement, Not Another Platform Fee

ELIYA AI is built specifically for e-commerce brands to answer which of their marketing spend is actually driving revenue. Which channel to double down and which campaign to pull back. ELIYA AI is specializes in measuring marketing impact, running Marketing Mix Modeling calibrated against real incrementality testing. ELIYA AI offers usage based pricing, offering a flexible way to perform marketing attribution and measurement at a fraction of cost.

In ELIYA’s analysis, on average 20% of ad spend is wasted in many e-commerce brands, and brands typically unlock a further 5-15% of incremental growth once that wasted spend is reallocated with ELIYA AI. Beliani, an e-commerce furniture retailer operating across five European markets, used ELIYA’s model to find that close to 24% of its media budget was going to saturated channels, and reallocating on the model’s recommendations drove 2.95M in incremental revenue with no increase in total spend. ELIYA runs this at a fraction of what a traditional measurement agency charges, since the model, not a large analyst team, does most of the heavy lifting.

VidMob: Best for Teams That Need Data on Which Creative Is Actually Working

VidMob is closer to an AI creative data company than a traditional agency. Its platform runs 40+ proprietary AI models against creative assets, drawing on 18 million assets across 300,000+ ad accounts, to score which specific creative elements, not just which campaign, are driving performance. It’s a strong fit for brand and creative teams that already believe their media spend is reasonably efficient and want to know why some ads outperform others.

Jellyfish: Best for Premium Brands Running Complex, Global Programs

Jellyfish is a full-service digital marketing agency that layers generative AI across media, creative, and data, including an AI Studio called Pencil that it says produces assets 55% faster. Its client roster, including Netflix, LVMH, and Swarovski, points to its sweet spot: large, established brands running complex, multi-market marketing programs that need an integrated agency partner rather than a point solution.

NoGood: Best for High-Growth Brands That Want Speed and Integrated Execution

NoGood describes itself as an AI-native growth marketing agency, building what it calls growth squads across paid, organic, creative, and answer engine optimization (AEO). It leans toward high-velocity experimentation over the statistical rigor of formal measurement, and serves both startups and enterprise brands like Nike and Intuit that want one team executing across channels quickly.

Smartly.io: Best for Enterprise Teams Producing Ads at High Volume

Smartly.io is an AI-powered platform, not a traditional agency, built for creative automation and cross-channel campaign management. It helps enterprise teams build and scale ad creative across social and connected TV in a fraction of the usual production time. It’s a fit for brands drowning in creative production volume, not brands trying to prove what that creative actually earned.

Brafton: Best for Enterprises That Need Content Produced at Scale

Brafton is a full-service content marketing agency that pairs its in-house creative team with two AI platforms, Brafton AI Studio and contentmarketing.ai, to produce SEO content, video, and design at scale. It primarily serves enterprises and growth-focused B2B companies that need a steady, high-volume content pipeline rather than a single campaign.

Ten Speed: Best for B2B Brands Optimizing for Both Google and AI Search

Ten Speed is a B2B organic growth agency focused on increasing visibility across both traditional search and large language models. Its AI-powered content and workflow tools are built specifically for SaaS, fintech, and tech companies trying to generate pipeline from organic and AI-driven search, rather than paid media.

How Do You Pick the Right AI Marketing Agency for Your Team?

The right answer depends on which part of your marketing engine is actually broken, not which agency has the best case studies.

• If you can’t tell which channels are actually driving revenue, that’s a measurement gap. ELIYA, and more narrowly VidMob, are built for that.
• If your creative output can’t keep pace with the channels and formats you need to fill, that’s a production gap. Smartly.io and Jellyfish are built for that.
• If your content pipeline can’t keep up with demand generation targets, that’s a content gap. Brafton and Ten Speed specialize there.
• If you need one team executing quickly across paid, organic, and creative without managing multiple vendors, that’s an integration gap. NoGood is built for that.

Frequently Asked Questions

What Should E-commerce Brands Look for in an AI Marketing Agency?

E-commerce brands should start by identifying whether their real gap is production (creative, content) or proof (measurement). Most brands already have more than enough agencies producing ads and content; what’s usually missing is a way to prove which of that output, and which channels, are actually driving incremental revenue rather than just claiming credit for sales that would have happened anyway.

Is ELIYA an Agency or a Measurement Platform?

ELIYA operates as both. ELIYA AI combines an AI-driven Marketing Mix Modeling platform with expert human review from ELIYA’s team of data scientists and ex-academics, plus a conversational AI Analytics assistant that lets clients query the model directly, so clients get a model and the analyst judgment to act on it, without paying for a full traditional measurement agency’s overhead.

Do AI Marketing Agencies Replace the Need for In-House Measurement?

Not entirely. Most AI marketing agencies on this list, outside of measurement specialists, focus on producing or executing marketing rather than proving its impact. Brands still need a dedicated measurement approach, whether an in-house team or a specialist agency, to know whether the output those agencies produce is actually working.

What’s the Difference Between an AI Content Agency and an AI Measurement Agency?

An AI content agency, like Brafton or Ten Speed, uses AI to produce more content, faster, at a given quality bar. An AI measurement agency, like ELIYA, uses AI to analyze what’s already happening across your marketing mix and prove, through models and controlled experiments, which of it is actually driving revenue. One creates marketing; the other tells you whether it worked.

How Much Do AI Marketing Agencies Typically Cost?

Cost varies significantly by category and scope. Full-service and growth agencies like Jellyfish and NoGood typically require larger retainers given the breadth of execution involved, while specialist and AI-native providers can often operate at a fraction of that cost since AI, not a large analyst or production team, handles more of the core work. ELIYA specifically is built to bring measurement analysis down to a fraction of what a traditional measurement agency charges.

The Bottom Line on the Best AI Marketing Agencies to Watch in 2027

The best AI marketing agency for you depends on what’s actually broken: creative production, content volume, growth execution, or proof that your marketing spend is working. Most e-commerce brands already have more than enough help producing marketing. What they’re usually missing is a way to prove which of it is real.

If you’re a growth-stage e-commerce brand that’s tired of paying a traditional measurement agency’s fees for numbers you can’t audit yourself, ELIYA AI is built for this.
