9 Top ChatGPT Ads Agencies For Successful OpenAI Campaigns

ChatGPT has ads now.

Yes, OpenAI, the company behind arguably the world's most popular AI assistant and chatbot, has rolled out ads.

These ads now appear below relevant ChatGPT responses as clearly labeled sponsored placements. They typically include an advertiser name, a headline, a description, an image, and a landing page.

They’re like search ads, if you will, but not quite. Unlike keyword targeting in search ads, OpenAI ads rely on contextual and conversational signals. And that could be a game changer. 

And it also changes what brands should look for in an agency. A strong partner needs paid search experience and a clear understanding of how LLMs interpret context and shape discovery. 

So, if you’re looking for a ChatGPT Ads agency, we’ve put together a list of early adopters and AI search specialists who can help you get started on solid ground. 

A Quick Rundown of ChatGPT Advertising Agencies

Is Running ChatGPT Ads Worth It?

ChatGPT Ads are worth testing for brands that heavily rely on search for product or service discovery. People are increasingly turning to AI assistants and LLMs for recommendations. These ads can be a new way for an audience to discover your business, particularly in an environment with high buyer intent. 

According to OpenAI itself, the platform has over 800 million weekly users, including one million business users. The latter makes the case for B2B brands to leverage ChatGPT ads, as buying committees may just be starting their search with AI queries. 

The reality is that search behavior is changing, and a large share of Google queries is shifting to AI tools and chatbots. McKinsey found that roughly 40% to 55% of consumers across sectors such as electronics, travel, apparel, beauty, grocery, wellness, and financial services use AI-based search to inform purchasing decisions.

But what’s even more interesting is that AI-referred shoppers are spending more, too. Adobe data showed that such visitors generated 53% more revenue per visit. That’s probably because those searching are ready to purchase. 

All this only reinforces the importance of search engine optimization (SEO) and generative engine optimization (GEO) to organically earn AI citations and recommendations. But the inclusion of LLM Ads offers brands a new opportunity to be readily visible in chatbot queries. That can be helpful for customer acquisition, qualified leads, and AI-driven discovery. 

Best Agencies for ChatGPT Ads (Early Adopters + Paid Search Pros)

Here are nine agencies that have a head start in OpenAI ads and are offering services dedicated to this new stream in paid search: 

1. Dentsu

dentsu is one of the strongest options on this list for brands that want direct exposure to the earliest phase of ChatGPT advertising. 

In February 2026, dentsu announced that they had joined OpenAI’s Ad Pilot Program as an early test partner, with several of their clients participating across industries including CPG, grocery, hospitality, retail, software, and travel. 

That gives them an advantage over firms approaching the platform only from the outside, since they can gather firsthand learnings about how ads perform within ChatGPT’s conversational environment. 

dentsu also brings significant scale, operating across roughly 120 countries and regions, along with established expertise in performance marketing, data, and AI-driven audience strategy.

Good match for: Enterprise brands seeking early pilot experience and global campaign scale. 

2. WebFX

WebFX is a digital marketing agency that has already begun testing ChatGPT Ads for clients. They’re one of the more hands-on options for those who want to experiment with the platform while it’s still developing. 

Their GEO expertise also allows them to connect paid campaigns with a brand’s wider presence in AI search. OmniSEO® identifies the prompts and topics where the brand appears, while RevenueCloudFX tracks both direct and assisted conversions from paid media.

WebFX treats ChatGPT as an additional media channel rather than a reason to pull budget from Google or Microsoft too soon. For brands ready to test it, the agency recommends a monthly ChatGPT ad spend of at least $5,000.

Good match for: Brands that want ChatGPT Ads connected to GEO, conversion tracking, and broader search visibility. 

3. 9AM

9AM is a performance media agency that brings their paid search playbook directly into ChatGPT Ads. They know how to build high-ROAS campaigns, test efficiently, and make performance decisions based on real data.

The agency has managed more than $250 million in ad spend across CPG, health and wellness, food, mobile apps, and other verticals. Their client list includes Hurom, Miro, Pros, and Hopper.

For ChatGPT Ads, 9AM combines sharp audience strategy with ongoing creative testing and careful measurement. They treat OpenAI Ads as part of the wider media mix, helping brands test the channel, learn quickly, and scale spend when the results support it.

Good match for: Established advertisers ready to add ChatGPT Ads to a mature performance media strategy.

4. Stackmatix

Stackmatix is a U.S.-based growth marketing agency with a strong focus on venture-backed startups and scaleups. 

They have worked with more than 200 startups, including companies backed by a16z, Sequoia, HF0, and Y Combinator. Their experience spans fintech, AI, SaaS, marketplaces, healthtech, ecommerce, and other fast-moving sectors. Previous clients include Figma, Kalshi, and CodeRabbit.

ChatGPT Ads fit naturally into Stackmatix’s wider SEO and AI search offering. They bring rapid experimentation, A/B testing, and close performance analysis to the channel, giving growth-stage companies a structured way to test OpenAI Ads and scale what works.

Good match for: Venture-backed startups and scaleups looking for fast, data-driven ChatGPT Ads testing.

5. Focus Digital

Focus Digital approaches ChatGPT as part of a wider AI visibility and demand-generation strategy. Their work is geared toward B2B companies that want to understand how AI discovery can translate into qualified traffic and leads.

They study the conversational intent behind buyer prompts and track how brands appear across ChatGPT and other AI search tools. They then connect that visibility to outcomes such as traffic quality and lead conversion.

Focus Digital starts with an AI visibility assessment and expands the investment when the opportunity is clear. Their offering is geared toward citations, conversational optimization, and organic AI discovery rather than hands-on campaign management through OpenAI Ads Manager.

Good match for: B2B companies that want to strengthen and measure their organic AI visibility before investing more heavily in ChatGPT Ads.

6. InterTeam

InterTeam is a B2B performance marketing agency invited by OpenAI to test ChatGPT Ads.

They start with the questions and comparisons buyers are already bringing to ChatGPT, then build campaigns around those conversations. As performance data comes in, they use CRM feedback to identify which ads are producing qualified leads and refine the campaigns accordingly.

Their approach connects ChatGPT Ads with the wider sales funnel, with campaign decisions based on lead quality rather than click volume alone. InterTeam only manages paid campaigns, though, so organic AI discovery is outside their scope.

Good match for: B2B SaaS companies that want ChatGPT Ads tied closely to lead quality and CRM data.

7. OneDay

One Day is a full-funnel advertising agency that offers a wide range of services, including AI search and, as part of that, ChatGPT ads. 

They focus on reaching users while they are researching their options and moving closer to a decision. This is particularly relevant for brands targeting professionals, founders, and other digitally confident audiences.

One Day tests how sponsored placements fit within real ChatGPT conversations, then uses performance signals and campaign learnings to sharpen the wider media and creative strategy.

Good match for: Brands that want ChatGPT Ads connected to a broader full-funnel advertising strategy.

8. RiseUp

RiseUp is a UK-based, AI-first growth agency with a measured approach to the still-emerging ChatGPT advertising market.

Rather than pushing brands to invest heavily from the start, they recommend contained, capped tests while building the data and infrastructure needed for AI-driven discovery.

RiseUp is geared toward established advertisers already spending across Google, Microsoft, Meta, or Amazon. They typically work with monthly media budgets between £10,000 and £500,000+, putting them firmly at the larger end of the market.

Good match for: Established advertisers that want to test ChatGPT Ads carefully alongside a substantial multichannel media program.

9. Maley Digital

Maley Digital is a PPC-only agency with a straightforward, performance-led approach to ChatGPT Ads.

Their team of 12 senior PPC specialists manages more than £20 million in annual ad spend across Google and Microsoft, as well as Meta. Every campaign manager has at least five years of hands-on PPC experience.

Maley Digital is realistic about where ChatGPT fits. They do not assume it will outperform established channels for every advertiser, so they judge each test against the brand’s existing conversion performance and commercial returns.

Good match for: Ecommerce and lead-generation businesses that want experienced PPC specialists to test ChatGPT Ads against clear commercial benchmarks.

What Should a ChatGPT Ads Agency Report Back?

A ChatGPT Ads agency should report how the budget was used, which campaigns generated meaningful actions, and what they plan to change next. Early AI-native advertising reports need enough detail to show where the results came from, rather than rolling everything into a single platform-wide number.

At minimum, reporting should cover:

• Delivery

Impressions, clicks, spend, CPC or CPM, and budget pacing. Where useful, the agency can compare these results with your core ad networks, provided the objectives and attribution windows are comparable.

• Conversion performance

The conversion event being measured, total conversions, conversion rate, CPA, and revenue where available. OpenAI reports click-through and view-through conversions separately, so the agency should distinguish between.

• Conversion paths

What visitors did after clicking the ad, including the landing pages they entered through and where they dropped out. For B2B campaigns, reporting should follow leads into the CRM to show lead quality and any contribution to pipeline growth.

• Creative and context

Results by campaign, ad group, and creative. The agency should explain which conversational situations produced the strongest response and how those findings will shape future sponsored units or landing pages.

• Next decisions

Which campaigns deserve more budget and which need another round of testing. This is where clear measurement frameworks and good conversion optimization are most important.

ChatGPT Ads may play a different role from other ad platforms, especially while the channel is still developing. A useful report should show whether the campaign is adding new demand capture, reaching valuable buyers, and producing enough evidence to guide the next test.

Things to Consider When Hiring an OpenAI Ads Agency

ChatGPT Ads are still new, and OpenAI Ads Manager remains in beta, which means most ad agencies will not yet have years of platform-specific experience or even ChatGPT Ads case studies. 

The platform itself is also evolving, from campaign creation and measurement to ad formats and delivery. 

With that in mind, it makes more sense to evaluate a ChatGPT Ads Agency based on transferable expertise and its understanding of AI-driven discovery. Here’s what that looks like: 

Prior Paid Search Experience

Strong paid search experience is one of the most useful foundations. Agencies accustomed to managing Google Ads (PPC services), conversion tracking, landing pages, bidding, and performance optimization already understand the discipline required to turn ad spend into measurable customer acquisition or qualified leads. 

ChatGPT uses richer conversational intent instead of solely relying on traditional keyword matching. That said, many of the fundamentals around testing, conversion performance, measurement and analytics, and budget allocation still apply.

Understanding of LLMs

The agency should also understand how LLMs and AI search platforms differ from conventional search engines. ChatGPT can interpret the broader context and intent of a conversation when determining ad relevance, which creates a different environment from targeting an isolated search query. 

That understanding can come from work on GEO projects. 

Look for a team that understands AI search, AI responses, contextual conversation matching, AI-driven discovery, and how people use an AI assistant throughout the buyer's journey. 

Ability to Connect ChatGPT Ads with SEO and GEO

For most brands, ChatGPT Ads would work best alongside organic discovery. A capable agency should understand how ChatGPT Ads can complement SEO and GEO efforts aimed at improving citation presence, authority, and brand visibility in AI-generated responses. 

You want a more connected search strategy in which paid media drives demand through sponsored placements, while content marketing strengthens the brand's organic presence across search engines and chatbots.
