An AI training data marketplace brings together companies that license their records and model builders that need them. Every dataset listed here is cleared against the Buckingham Data Clearance Standard before a buyer sees it.
The marketplace lists records that companies create in the course of their work. This data is not on the public web.
Datasets come from companies across the economy, including professional services, logistics, manufacturing, retail, healthcare administration and financial services. Records from companies that are closing or being sold are listed on the same terms.
A listing gives a buyer enough to decide whether to ask for a sample. The company is not named.
| Field | What it shows |
|---|---|
| Record types | The kinds of record in the dataset and how they link together |
| Sector and country | The kind of business the records come from, and where it operates |
| Coverage | Date range, languages and volume |
| Permitted uses | Training, fine-tuning, evaluation, retrieval and commercial deployment, each stated separately |
| Exclusivity | Whether an exclusive licence is available, and for which field of use |
| Clearance | The clearance result, its date and the version of the standard applied |
Model builders license cleared datasets. Companies list the records they hold.

Company records are the data that model builders cannot gather from the public web. The marketplace gives them one place to license those records, and gives companies a route to market in which every dataset is cleared before it is offered.
