        7. Bloom

        7. Bloom

        Bloom is a marketing and technology consultancy based in Sabadell that serves businesses across the Barcelona metropolitan area. Its current ChatGPT Ads service covers account preparation, campaign strategy, conversational intent, ad copy and creative, landing pages, measurement, and media investment.

        Because Bloom also works on wider digital marketing and technology projects, it may suit smaller and mid-sized businesses that need help beyond the media buy itself. Landing page improvements and tracking can be handled alongside the advertising campaign, which is useful for companies entering ChatGPT Ads without an existing setup for the channel.

         

        Key Facts:

        8. Dentsu

        8. Dentsu

        Dentsu offers a different route into ChatGPT advertising for large organizations. OpenAI identifies Dentsu as one of the agency partners working with its advertising platform, alongside Omnicom, Publicis, and WPP. These partnerships cover areas such as media planning, budgeting, bidding, creative, and campaign execution.

        The group’s Spanish operation has a Barcelona office and includes media brands such as Carat, Dentsu X, and iProspect. This structure makes Dentsu more relevant to advertisers that need ChatGPT incorporated into a large cross-channel media plan, potentially across several countries, brands, or business units.

         

        Key Facts:

        • Best for: Large and enterprise advertisers
        • Core services: Integrated media, digital advertising, media planning, performance marketing

        9. OMD Spain

        9. OMD Spain

        OMD Spain is part of Omnicom Media, giving Barcelona advertisers access to one of the global agency groups working directly with OpenAI on its advertising platform. OpenAI names Omnicom among its agency partners for ChatGPT Ads.

        OMD has a physical Barcelona office and focuses on media strategy, planning, buying, data, and campaign effectiveness. It is therefore more likely to suit established advertisers with substantial multi-channel media programs than businesses looking only for a small ChatGPT Ads test. The group connection is important here: OpenAI’s announced partnership is with Omnicom, rather than a separate partnership specifically attributed to the Barcelona OMD office.

         

        Key Facts:

        • Best for: Established brands with large media programs
        • Core services: Media strategy, planning, buying, data, performance marketing
        • ChatGPT Ads connection: Parent group Omnicom is named as an OpenAI agency partner
        • Location: Barcelona office
        • Notable strength: Integration with wider Omnicom media capabilities

        • Phone: +34 934 458 000
        • Address: Carrer de la Marina 16, 08005 Barcelona, Spain
        10. Starcom Spain

        10. Starcom Spain

        Starcom is part of Publicis Groupe, another major agency group that OpenAI identifies among its ChatGPT Ads partners. This gives Starcom a credible route into the new channel through the wider Publicis media organization, while its existing work centers on media planning, communications strategy, data, and advertising technology.

        Starcom maintains an office in Barcelona, making it relevant to major advertisers that value local account access but need campaigns coordinated through an international media network. As with OMD, the OpenAI partnership is announced at parent-group level rather than specifically for the Barcelona office.

         

        Key Facts:

        • Best for: Large consumer brands and international advertisers
        • Core services: Media planning, communications strategy, digital advertising, data
        • ChatGPT Ads connection: Publicis is named by OpenAI as an agency partner
        • Location: Barcelona office
        • Notable strength: International media capabilities combined with local presence

        11. WPP Media

        11. WPP Media

        WPP has been directly involved in the early development of ChatGPT advertising. OpenAI identifies WPP as an agency partner, while WPP Media has also discussed participation in the ChatGPT Ads pilot with advertisers across sectors including automotive, consumer goods, entertainment, luxury, retail, technology, and travel.

        WPP Media currently recruits for Barcelona-based positions, indicating an operating presence in the city, although its public Spain contact page lists Madrid as its principal Spanish office. It is therefore most appropriate for Barcelona companies looking for large-scale media capabilities rather than an exclusively local boutique relationship.

         

        Key Facts:

        • Best for: Enterprise advertisers and multi-market campaigns
        • Core services: Media planning, media buying, data, technology, performance marketing
        • ChatGPT Ads connection: WPP is an OpenAI agency partner and WPP Media participated in the advertising pilot
        • Notable strength: Experience connecting new advertising channels with global media programs

        Abschluss

        Businesses looking for ChatGPT Ads agencies in Barcelona can choose from local digital marketing teams as well as agencies offering broader paid media, AI marketing, and search visibility services. When evaluating providers, it is useful to consider their experience with campaign setup, audience targeting, creative testing, conversion tracking, and ongoing optimization rather than focusing only on the initial launch.

        The right agency will depend on the company’s acquisition goals, budget, existing advertising channels, and need for ongoing support. ChatGPT Ads can complement Google and Meta campaigns or form part of a wider strategy that includes SEO and AI search visibility. This guide provides a starting point for comparing agencies in Barcelona and identifying a provider that fits the company’s marketing needs.
