Country: United States
GEO Agencies in the United States
US-headquartered agencies doing generative engine optimization, weighted towards SaaS, professional services, healthcare and fintech, working on how companies are cited and recommended by ChatGPT, Perplexity, Gemini and other AI assistants.
The US holds the largest share of the directory, and the concentration follows the software industry rather than the advertising one. New York and Austin account for the biggest clusters, with the San Francisco Bay Area behind them, and the rest spread thinly from Portland to Raleigh.
The service mix tells you what these agencies think the work is. Digital PR and source-of-truth content appear most often, followed closely by technical SEO. That combination reflects a common view: being cited by an assistant depends on being written about elsewhere and being readable when the crawler arrives, not on one or the other.

Common questions
Do these agencies only work with US clients?
No. Many work internationally. A US headquarters says where the team is based, not who it will take on.
Does it matter which US city an agency is in?
Rarely. GEO work is almost entirely remote, so a city matters for time zone overlap and for meeting in person if you want that. It does not affect the technical work.
What do US agencies in the directory tend to specialise in?
SaaS and software is the most commonly named industry, followed by professional services, healthcare, fintech and ecommerce. Services are tagged only where an agency names them on its own site.
Which agencies qualify for this page?
Agencies in the directory with a US headquarters. The page updates as new US agencies are added.
