Marketing agencies in Cincinnati: 227 offices in a consumer-brand town, across three states

This report is for Cincinnati-area brands and businesses hiring a marketing agency, people sizing the local market, and vendors that sell to agencies.

Cincinnati's agencies in one table

Source: US Census Bureau, County Business Patterns (CBP) 2023, for the Cincinnati, OH-KY-IN Metro Area (CBSA 17140) and NAICS 5418, Advertising, Public Relations, and Related Services. CBP counts establishments with paid employees, so the many independent brand consultants and freelancers who work for Cincinnati's consumer companies aren't included.

Three states, one market

The Census Bureau published Boone and Dearborn counties' employment but flagged it as high-noise: its confidentiality noise moved those figures by 5% or more. Three more establishments are in the metro's other counties. Hamilton County dominates, at about 20 employees per office. Northern Kentucky has 35 of the 227.

By size, 145 have one to four employees, 31 five to nine, 21 10 to 19, 17 20 to 49, 8 50 to 99 and 3 100 to 249. The Census Bureau doesn't publish the classes above 250 (it drops cells with fewer than three establishments); the total shows 2 establishments have 250 or more. So 197 have fewer than 20 employees, 25 have 20 to 99, and 5 have 100 or more, a figure derived as the total less the smaller bands.

A market shaped by consumer brands

The Procter & Gamble Company, at One Procter & Gamble Plaza, reported in its 10-K that advertising costs, covering "television, print, radio, digital and in-store advertising," were $10.2 billion in fiscal 2026 (the year to 30 June), up from $9.2 billion. That is a worldwide figure, not spending in Cincinnati. The local agency mix looks like this:

Four media buying offices (541830) complete the 227; their employment figure is high-noise. Employees per location is our calculation. The material distribution businesses, the people who run in-store sampling and coupon drops, average 63 employees each, more than any other type with a reported figure. PR is thin: 26 offices with 58 people. Separately, CBP counts 272 marketing consultancies (541613) and 117 graphic design studios (541430). For which code fits which firm, see the NAICS code for marketing.

Hiring for brand work: what to check

Agencies that serve big consumer companies typically work within brand guidelines, approval chains and test budgets. If you're a smaller brand, ask for those habits without the big-brand overhead:

• Brand work like yours. A case study in your category and price point, with the results the client measured, not just the creative.
• Who's on your business. At an agency with a very large client, ask where your account sits and who covers it during that client's launches.
• Retail and shopper experience, if you sell through stores: in-store, sampling, retail media. Ask which parts the agency does itself and which it subcontracts.
• Your accounts stay yours. Google's advertiser guide says an agency "must set up a separate Ads account for you." On Meta, keep the ad account in your own business portfolio; Meta says a partner with full control "cannot share the business asset with another business."
• The creative is assigned to you. Commissioned work is a "work made for hire" only in the nine categories the Copyright Office lists, with a signed agreement. Get a written assignment on payment.
• A clean exit. Stagwell's 10-K says its contracts "typically provide for termination by either party within 30 to 90 days."

Selling to Cincinnati agencies

The market is small enough to cover by hand: 227 establishments, 30 of them with 20 or more employees. The founder decides at most of the 197 smaller offices; at the larger ones, look for an operations or production lead.

Illustrative example. The company and figures are invented.

Sampleset (sampleset.example) sells event and sampling staff scheduling software at $450 a month. Its natural targets are the 10 material distribution businesses and 53 other advertising services firms, which run sampling and demonstrations: 63 in all. If an illustrative 40% run field staff, about 25 fit, worth about $135,000 a year if each bought. The opener mentions a recent in-store program the firm has posted about and the scheduling load that comes with it. Checking which firms run field teams means reading each site and job post; Bebop does that research for each account in a list. For method, see how to build a prospect list.
