How is AI used for marketing?
AI has replaced or accelerated four categories of marketing work: content production (drafting, editing, repurposing), personalization (segmenting audiences, dynamic email content, ad variants), analysis (extracting insights from CRM and web data), and creative production (image, video, voice). The teams getting real returns aren't "using AI". They're rebuilding their content and campaign workflows around AI as the default first draft.
How big the AI services market is here
105 US listings in The Wall are filed under AI Marketing, with a median founding year of 2019 and 32 founded in 2020 or later. It is the youngest discipline in the index by a clear margin.
On the service field, 33 listings name AI consulting. Against 3,460 approved US listings overall, that is a small specialist market sitting alongside a much larger one where AI is a tool inside existing services rather than the service being sold.
What it costs is worth knowing before you take a meeting. 71 of the 105 AI Marketing listings publish a minimum project size, 53 of those open at $5,000 or less, and 17 require $25,000 or more.
How to use this
When a firm pitches AI, ask which step of your process it removes and what happens when it gets that step wrong. Vendors who have actually deployed it answer that quickly. The rest describe capabilities.
How this was computed. Every figure on this page is counted from The Wall's own directory of approved, US-headquartered, machine-verified-live listings: 3,460 of them in the snapshot captured 2026-09-14. Rates, minimum project sizes, team sizes, founding years and ratings are provider-declared figures published on public profiles. 1,738 of those listings publish a service list, and that field holds at most 4 services per firm, so service counts are counts of what firms name first rather than everything they sell. Percentages of disclosed values exclude listings that publish no figure. Nothing here is modeled or estimated. Sourcing standards: editorial policy.
Why this matters
Google puts this question in People Also Ask for the "ai marketing tools" query, which means buyers are asking it while they shop. The Wall answers it from the directory position: we index 3,460 verified US growth-services vendors across 10 pillars, so the figures above come from those records rather than from a survey.
If you are evaluating vendors in this category, the AI Marketing pillar page carries the full US firm list with rate, team size and headquarters filters.
