Selling a marketing agency? Its briefs and feedback rounds have another buyer

An agency acquirer pays for the team, the retainers and the client relationships. Your archive captures the craft: each brief, the opening concept, client feedback, the revisions and the final approval.

That request, draft, feedback, revision loop is precisely what AI companies want to learn from.

Is my agency big enough?

Floors usually fall between 20 and 30 staff. If your agency grew by buying others, total up headcount across all of them.

Your clients' brand files and ad accounts

Brand assets, ad account data and campaign results usually belong to clients. Buyers say client data can be excluded. Keep the scope to your own process and anonymised correspondence.

What the published agency deal tells you

The one published agency figure is a $110,000 license from Polyshares, by its own account. It is a data point, not a benchmark, and the price for your agency will depend on size, years and scope.

Questions to put to any data buyer

Is this a license of a copy, or a sale of the records outright?
Is it exclusive, and for how long? Can I license the same data elsewhere later?
Which systems and date ranges are in scope, and can I leave folders or whole tools out?
Who removes names and personal details, how, and do I approve a sample before anything leaves?
When does payment arrive, and does the clock start at signing or at your acceptance of the delivery?
Do I pay anything, and does anyone in the chain take a cut?
How long do you keep the copy, and what happens to it if you are acquired?

FAQ

Questions, answered

Has a marketing agency been paid for data?

Polyshares says it licensed one agency's data for $110,000.

Is my company big enough?

The usual floor is somewhere from 20 to 30 staff. Some buyers publish none at all. Mode accepts law firms with 6 people and accounting firms with 10, and Pewter goes by your highest-ever headcount. Our match quiz sorts it out in two minutes.

What could a license pay?

For a business that is still trading, most buyers publish bands of roughly $100K to $2M. Treat those as marketing claims. They are no price for you. Only a written offer from a buyer whose criteria you meet tells you what your data is worth.

Do I pay anything to license?

Typically no. Direct buyers rarely charge sellers. Middlemen are different: brokers and marketplaces may keep anywhere from 8% to 30%. Have any fee written down before a sample changes hands.
