04ChatGPT Ads inside a wider service
These B2B agencies also run ChatGPT Ads, without a page that offers it as a service of its own.
- ToJupiter: London. A paid media agency for B2B SaaS. ChatGPT Ads appear in its sample plan as "learning only, $500 a month", and it quotes "$3 to $5 a click to start". There is no ChatGPT Ads page.
- The Growth Syndicate: Amsterdam. A B2B marketing agency that lists ChatGPT Ads as a channel on its PPC page. Its own article says the B2B accounts it ran showed "no meaningful downstream events" and concludes: "For most B2B advertisers, not yet."
- YOYABA: Hamburg. Works only with B2B software companies. A field report on its blog covers a ChatGPT Ads campaign it ran in June 2026 for a US legal-tech SaaS client: about $3.06 a click over the first ten days. There is no service page.
05How we chose them
Google shows hundreds of agencies with a ChatGPT Ads page for searches in the UK, Germany, Austria, Switzerland, the Netherlands, Sweden, France and Spain, and most of them say they work for any kind of business. We screened 42: those whose sites or ChatGPT Ads pages mention B2B, those named on published ChatGPT Ads agency lists, and the B2B paid media agencies on our agency comparison. An agency is listed when its own site shows all three:
- a page that offers ChatGPT Ads as a service;
- a focus on B2B companies, on the site or on that page;
- an office in the EU, the UK or Switzerland.
Fifteen have a ChatGPT Ads page but no stated B2B focus. Thirteen are B2B agencies without a ChatGPT Ads offer; three of them appear above. Five meet neither rule, and one blocks automated reading of its site. Every fact was read from the agency's own pages on 3 November 2026; nothing is taken from another agency's list.
06What we could not verify
- Five of the nine publish no fee for ChatGPT Ads: Blend, COSEOM, Hey Digital, Linkedist and Nexa Growth.
- Results are quoted as each agency publishes them, with its own measurement; Lever Digital and Blend give no period or counts.
- Partner status is each agency's own statement. We did not check it with OpenAI.
- Where a site gives two answers to the same question (GROWSaaS and Vogler Marketing on contract terms), both are shown.
07Buyer questions
Which agencies run ChatGPT Ads for B2B companies in Europe?
Nine agencies with an office in Europe publish a ChatGPT Ads offer for B2B companies: Demandgap (Vienna), Blend (Reading), COSEOM (Barcelona), GROWSaaS (Seevetal, near Hamburg), Hey Digital (Tallinn), Lever Digital (Edinburgh), Linkedist (Kaunas), Nexa Growth (Wolverhampton) and Vogler Marketing (the Allgäu). ToJupiter, The Growth Syndicate and YOYABA also run ChatGPT Ads, as part of a wider paid media service.
How much does a ChatGPT Ads agency cost in Europe?
Four of the nine publish a fee. Vogler Marketing charges €680 for setup, then €290, €690 or €1,390 a month. GROWSaaS sells fixed-price tests at €990, €1,790 and €2,990. Lever Digital adds ChatGPT Ads to its retainer for £500 a month. Demandgap sells a €1,200 audit, or a pilot billed at €150 an hour, with a standard setup of €2,250. The others quote on request. Ad spend is paid to OpenAI on top.
How much ad budget does a first ChatGPT Ads test need?
Demandgap starts pilots from about €1,200 of ad spend, which buys 500 clicks at the €2.32 per click its B2B software clients paid on average from September to early November 2026. Lever Digital recommends £1,000 to £3,000 a month over 8 to 12 weeks. Vogler Marketing and GROWSaaS set no minimum, and Hey Digital sets no ChatGPT Ads test budget.
Which agencies publish ChatGPT Ads results?
Demandgap publishes figures from three B2B software clients: €2.32 per click on average from 9 September to 2 November 2026, and for one DACH client €101 per product tour against €56 on its non-brand Google search. Lever Digital publishes one UK SaaS client: £1.96 per click against £36 on Google Ads. Blend gives CPCs of $3 to $5 from tests on its own budget. Vogler Marketing names a client, without figures.
Are any of these agencies OpenAI partners?
Demandgap says it is an OpenAI Select Partner. None of the other eight claims partner status on its site, and Hey Digital says it is not affiliated with OpenAI. When OpenAI brought ChatGPT Ads to Europe, it said advertisers could buy through its own Ads Solutions team, agency partners and technology partners, with self-serve Ads Manager to follow. We did not check any agency's status with OpenAI.
Can European companies run ChatGPT Ads?
Yes. OpenAI expanded ChatGPT Ads to 31 European countries in August 2026, among them Germany, Austria, France, Spain, Italy, Sweden and the Netherlands. The ads reach only users on the Free and Go plans; Plus, Pro and Enterprise stay ad-free.
Is this list independent?
No. Demandgap publishes it and is on it. Every fact about another agency comes from that agency's own website, read on 3 November 2026, with the source pages under each entry. To correct an entry, write to office@demandgap.com.
