94% of marketers say they use AI. Only 17% have transformed how they work around it. That gap is where most agencies live, running the same workflows they always have, with a chatbot bolted on.
The seven agencies below are in that 17%. They have rebuilt delivery around AI, and it shows in what they can do and how fast they move.

Top AI Marketing Agencies in the USA

RZLT - AI-Native Marketing for B2B Tech, AI Startups and Web3

RZLT is an AI-native marketing agency founded in 2018, built specifically for B2B tech, AI-first startups and Web3. They've rebuilt their entire delivery model around agentic systems, so content production, SEO, go-to-market strategy, and investor positioning all run through automated workflows rather than manual tasks. It's one of the few agencies that can speak to a technical product without needing it simplified first. 

Persado - AI-Generated Marketing Language

Persado was founded in 2012 in New York City, and it's built entirely around AI-generated marketing copy. Their platform, Motivation AI, analyzes the emotional triggers behind messaging and generates variants that are statistically more likely to convert. They work with enterprise brands in financial services, retail, and healthcare, so smaller teams will probably find them out of budget. 

NoGood - AI-Ops for Marketing Workflows

NoGood is a New York-based growth agency founded in 2017, with clients that include TikTok, Nike, and Spring Health. Their Goodie AI platform tracks brand visibility across answer engines like ChatGPT, Claude, and Perplexity, which is a capability most agencies haven't caught up to yet. They run small, embedded squad teams rather than the large org structures that make traditional agencies slow. 

Hawke Media - Fractional CMO Model with AI Tooling

Hawke Media launched in Los Angeles in 2014 with a CMO-as-a-service model designed to give growth-stage companies access to senior marketing talent without a full-time hire. They've since expanded across e-commerce, DTC, and SaaS, integrating AI tooling into media buying, creative testing, and performance reporting. Their a-la-carte structure means you can bring them in for one specific function and expand from there.

Single Grain - AI Content Strategy and SEO

Single Grain is a fully remote agency led by Eric Siu, who also runs the Marketing School podcast. They've published extensively on how they use AI in actual client work, including specific ChatGPT workflows and automation case studies, which gives you a clear sense of how they operate before you've spoken to anyone. Their strength sits in organic growth and paid acquisition across SaaS, e-commerce, and education.

Wpromote - Unified Performance Dashboards

Wpromote is headquartered in El Segundo, California, and it has built a strong reputation in performance marketing for brands that want to compete aggressively regardless of budget size. Their proprietary platform, Polaris, centralizes campaign data and surfaces AI-driven recommendations across paid search, social, and programmatic. They were named Google's Performance Max Partner of the Year, which shows depth on the paid media side.

Tinuiti - AI for Retail and DTC

Tinuiti has offices in New York, Atlanta, and Los Angeles, and it's one of the larger independent performance marketing agencies in the US. They cover the full funnel across Amazon, Google, Meta, and streaming TV, and they've built a proprietary measurement suite called Bliss Point to help brands track where their spend is actually having an impact. Cross-channel attribution is a real headache for mid-market and enterprise brands, and Bliss Point takes a serious run at solving it. 

How to Choose an AI Marketing Agency

Start with your primary objective, whether that's performance media, organic growth, AEO, Web3 go-to-market, or something else, and find an agency with a real track record in that specific area. Check whether their AI capabilities are reflected in how they actually deliver work, not just how they pitch it. Run a small pilot before committing to a longer engagement. How a team communicates, reports, and handles early feedback will tell you more than any case study.
