AI Marketing Agencies for Enterprise Clients (September 2026)

"AI marketing" means several different purchases at enterprise scale, and the firms here sit at different points across them. Converteo's Sharlie, the voice agent behind Orange's Sosh brand, is a customer-facing system: the write-up records a voice-to-voice architecture committed to in April 2024, before the model reached general availability, specifically to avoid a later migration off a speech-to-text pipeline. Ekimetrics comes from the measurement side, with twenty years of marketing-mix modeling and named clients including Nestlé, Estée Lauder and Renault, though its most detailed published cases are anonymized. wukonig works the newest surface, generative engine optimization: whether an assistant names your brand when a buyer asks it for suppliers, measured with a fixed question set repeated across systems. Jakala brings the group-scale option, selling a marketing and data program rather than a system, with a hotel-group campaign published at 29 percent more bookings.

Those are separate budgets with separate owners—customer experience, marketing effectiveness, and search. Decide which one you are actually buying before the first call, because the shortlist changes completely depending on the answer. Then ask the same question of whichever direction you pick: which number moved, what it was measured against, and over what period. Enterprise marketing is a discipline with a long tradition of attribution arguments, and the arrival of AI has not settled any of them.
