AI Marketing in United States

This page covers the 8 AI marketing companies in this directory that are headquartered in United States. That is 67% of the 12 AI marketing companies tracked across every country, which makes United States the largest of the 4 national clusters in this category. Headquarters location matters for buyers who need contracting in a local legal entity, data residency inside United States, or overlapping working hours with an in-country delivery team — so the list below is filtered on stated headquarters, not on sales presence or reseller coverage.

Company size varies widely across the United States cohort. Of the 7 companies here that publish a headcount range: 1 in the 51-200 band, 3 in the 201-500 band, 1 in the 501-1000 band, 2 in the 1000+ band. The most common profile is 201-500 employees (3 companies), which is a useful signal when you are weighing a boutique AI marketing team that will give you senior attention against a larger firm that can absorb a multi-workstream programme. Headcount bands are self-reported and are left blank rather than estimated for the 1 company that do not disclose one.

5 of the 8 companies disclose a total raised figure, summing to $1.2B across those companies; the largest disclosed total is 6sense at $500M. Funding is only listed where a company or a credible public source has stated it, so an absent figure here means undisclosed, not zero — several profitable, bootstrapped AI marketing companies in United States raise nothing at all. Stated funding stages in this cohort: Public (NYSE: ZETA) (1), Series A (1), Series B (1), Series C (1), Series D (1), Series E (1), Venture (Goldman Sachs-backed) (1).

Several of these United States companies are not AI marketing pure-plays. Counting the other directory categories the same companies appear in: AI Platforms (1). If you would rather consolidate work with one supplier than run several, those overlaps show which United States providers already do adjacent work — and which are single-category specialists.

Contracting notes specific to United States suppliers. There is still no single federal omnibus privacy statute — the American Privacy Rights Act expired without a vote at the end of the 118th Congress — so obligations come from the states instead. Twenty states now have comprehensive consumer privacy laws in effect, with Indiana, Kentucky and Rhode Island's taking effect on 1 January 2026; California's CCPA as amended by the CPRA remains the broadest and the only one carrying even a limited private right of action. Sectoral rules layer on top of that: HIPAA where the work touches health data, GLBA where it touches consumer financial data, and FedRAMP authorisation where the buyer is a federal agency. The practical question to put to a United States vendor is which specific state regimes its standard data processing agreement is already mapped to, and in which states or regions the processing and any sub-processing physically happens.

Every entry is drawn from the same independently maintained AI marketing directory as the rest of the site. Placement is not sold, the order is alphabetical rather than ranked, and the listing is not auto-scraped. Where a field is unknown it is shown as unknown rather than filled with a guess, so you can see exactly how much is on the record for each United States provider before you contact them.
