What are the 5 best ChatGPT Ads agencies in France in 2026?

Sponsored cards have been appearing below ChatGPT responses in France since August 24, 2026. Since then, many agencies have added a page ChatGPT Ads to their website, and some still claim that the ad platform is not available here. At Growth Room, we manage Google Ads, Meta, LinkedIn, and GEO for our clients, and our ChatGPT Ads agency team has been managing this channel since its arrival in France. We have reviewed the offerings of the French agencies that discuss it and selected the five that describe a precise and up-to-date methodology.

Key takeaways

• ChatGPT Ads has been open in France since August 24, 2026, and available via self-service since August 31.
• Ads appear below the response, and only users on Free and Go plans see them.
• Targeting is based on the context of the conversation, without keywords.
• We recommend a media budget of at least €2,500 per month for 6 to 8 weeks for an initial test.
• Our selection: Growth Room, Cosmo5, impulsion.com, Make Sense, and Daware.

What is the status of ChatGPT Ads in France as of October 2026?

OpenAI opened its ad platform in 31 European countries, including France, on August 24, 2026. During the first week, advertisers had to go through OpenAI's sales teams or a partner agency. Since August 31, theAds Manager has been accessible via self-service to any eligible business.

How it works in brief:

• the ad is a card marked "Sponsored" below the ChatGPT response, with a headline of about 16 characters, a description of about 32 characters, an image, and a link;
• Plus, Pro, and Enterprise subscribers do not see any ads;
• the advertiser describes to the ad platform the conversational situations where their offer is useful, what OpenAI calls context hints;
• purchasing is done via CPM or CPC, with a minimum of €25 per day;
• conversions are tracked using the pixel OpenAI and the Conversions API.

The details of the ad platform are explained in our guide to ChatGPT Ads.

How did we choose these agencies?

No French agency has yet published a series of client case studies on ChatGPT Ads. We used the following criteria:

• a ChatGPT Ads page updated after the French launch;
• a detailed measurement method, including pixel and Conversions API;
• verifiable experience with Google Ads, Meta, or LinkedIn Ads;
• accurate information about the channel, without fabricated French performance figures.

Agencies that still present France as a closed market, or that claim to be number one without describing their methodology, are not included in this list.

What are the 5 best ChatGPT Ads agencies in France?

1. Growth Room: paid search, tracking, and GEO in the same team

We are a Paris-based growth marketing agency and have supported over 150 companies. Our consultants manage Google Ads, Meta Ads, LinkedIn Ads, and GEO on a daily basis.

To build context hints, we start from the same mapping as in GEO : the list of questions prospects ask ChatGPT before choosing a product or service provider. Measurement is set up before the first impression. Our COO led a team at fifty-five, and every consultant personally installs the pixel, the Conversions API, and the conversion reporting in HubSpot or GA4.

Our first ChatGPT Ads campaigns are running, and we will publish their figures once they are consolidated. For the ad platforms we have been managing for longer, the same method has yielded these results:

• Déménager Facile: 425 leads in 2 months on Google Ads, for an average cost per lead of €29, which was reduced by about 3x during the campaign;
• Airties: cost per MQL 9 times lower than the target by the third month, after shifting from lead volume optimization to MQL optimization;
• across 4 B2B accounts tracked over 10 months, the qualification rate increased by up to 109% once the ad platform was connected to the CRM.

For ChatGPT Ads, we therefore evaluate campaigns based on the cost per qualified lead. The testing method is detailed in our article ChatGPT Ads: building an initial test and deciding on the next steps, and our Search results are included in our summary of Google Ads case studies.

Target clients: SMEs, scale-ups, and mid-market companies, B2B or e-commerce, looking to test ChatGPT Ads alongside Google Ads and SEO.

2. Cosmo5: official OpenAI partner, focused on enterprise accounts

Cosmo5 is the new name for the Labelium group, a Search specialist founded in 2001 and rebranded in 2025. The group has 1,300 employees across 30 offices. OpenAI selected it as an official partner for the European launch of ChatGPT Ads, and Cosmo5 launched campaigns for ten clients in France and Spain within the first week.

The group integrates ChatGPT Ads into international media plans and works directly with OpenAI teams. Its entry requirements are better suited for advertisers who already have significant media budgets.

Target clients: large advertisers with a presence in multiple countries.

3. impulsion.com: proprietary campaigns active from day one

impulsion.com is an online advertising agency based in Montpellier and founded by Sébastien Rech. It reports ten years of operation, over 190 clients, and €11M invested in advertising. The agency has been running its own ChatGPT Ads campaigns since the French launch, with the pixel and Conversions API installed from day one.

The process involves four steps: selecting conversation contexts, creating cards, setting up measurement, and then comparing the cost per acquisition against other channels. The agency is also a training organization, which may be of interest to companies looking to bring management in-house later on.

Target clients: SMEs and e-commerce businesses.

4. Make Sense: e-commerce and technical prerequisites

Make Sense For Digital is a performance marketing agency based in Bondues, near Lille. They work with over 100 e-commerce brands. For ChatGPT Ads, they verify several technical points before launching campaigns: access for OAI-AdsBot and OAI-SearchBot to landing pages, retention of the click ID after a redirect, and conversion deduplication between the pixel and Conversions API.

Ad groups are built based on client needs, and results are measured against actual revenue. The agency does not share performance benchmarks for the French market until they have their own data.

Target clients: E-commerce brands and DNVBs already using Google Ads and Meta.

5. Daware: structured content and catalogs before activation

Daware is a Paris-based agency covering SEO, GEO, SEA, tracking, and social ads. For ChatGPT Ads, they begin by auditing the brand's presence in ChatGPT responses and structuring content and product catalogs.

Their method consists of five steps, from audit to monitoring. Bidding is managed via CPC or oCPC, and the pixel and Conversions API are linked to existing paid media reporting. The agency holds a 5 out of 5 rating across 29 reviews and cites clients such as Octopus Energy.

Target clients: Companies looking to entrust SEO, GEO, and ChatGPT Ads to the same provider.

Comparison table of ChatGPT Ads agencies

Which ChatGPT Ads agency should you choose based on your profile?

• Large advertiser present in multiple countries: Cosmo5, which works directly with OpenAI.
• B2B SME or scale-up already using Google Ads: an agency capable of linking ChatGPT Ads to the CRM and comparing the cost per qualified lead across channels.
• E-commerce brand: an agency that masters catalogs, landing pages, and revenue-based measurement, such as Make Sense or impulsion.com.
• Company that also wants to be cited in ChatGPT responses: an agency that handles GEO in addition to advertising. We present this work on our page GEO agency.

How much does a ChatGPT Ads campaign with an agency cost?

With €750 per month, ads will run, but each ad group receives too few conversions to be compared against others. We therefore recommend a test budget of at least €2,500 per month, just as we do for an initial Google Ads or LinkedIn Ads test.

What questions should you ask a ChatGPT Ads agency before signing?

• Do you have active campaigns in France, and since when?
• How do you install the tracking (pixel, Conversions API, CRM integration) before the launch?
• What data do you use to build the context hints?
• Which metric will you use to evaluate the test: cost per qualified lead, ROAS, or customer acquisition cost?
• How will you compare ChatGPT Ads with Google Ads and Meta at the end of the test?
• Will the ad account be opened in our name?

Be wary of agencies that promise a specific cost-per-click for the French market, or whose website still claims the platform is unavailable in France.
