The marketplace for cleared company data

Prepared by the Buckingham Capital Consulting data services team · 11 November 2026

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.

What is listed

The marketplace lists records that companies create in the course of their work. This data is not on the public web.

  • Communications: email and chat threads, call transcripts and meeting notes.
  • Documents: reports, proposals, procedures and forms, with their versions and edits.
  • Workflow records: tickets, cases, approvals and task histories that follow a piece of work from start to finish.
  • Structured data: spreadsheets, transaction tables, logs and system records.

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.

What each listing shows

A listing gives a buyer enough to decide whether to ask for a sample. The company is not named.

Sector and countryThe kind of business the records come from, and where it operates

How it works

Model builders license cleared datasets. Companies list the records they hold.

  • Model builders: send a specification, review matching listings under a confidentiality agreement, test a sample and license the dataset.
  • Data owners: describe the records you hold, have them cleared against the standard and approve each licence before any data is delivered.
  • Data brokers: list datasets you represent once each has a clearance record.

Further detail

Background

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.

Where no listing matches a specification, we approach companies that hold suitable records and clear a dataset to order.

Listing a dataset

StageWhat happensWhat you receive
1. DescriptionYou describe the records you hold: types, systems, years and volumeA view of what can be listed
2. ClearanceThe dataset is assessed against the six requirements of the standardA clearance record or a findings report
3. ListingThe cleared dataset is listed without your company's nameYour approved listing

5. DeliveryDe-identified records are delivered to the buyerPayment under the licence

You keep ownership of your records throughout. A licence gives the buyer permission to use a copy for the purposes it names.

Confidentiality

  • Listings: no listing names the company or contains any record from the dataset.
  • Buyers: a buyer sees a data sheet and a clearance record only after signing a confidentiality agreement.
  • Identity: the company's name is disclosed to a buyer when the company agrees, usually when the licence is drafted.
  • Data: identifiable records do not leave the company's systems at any stage.

What is not listed

  • Uncleared data: any dataset without a clearance record.
  • Personal data: any dataset in which people can be identified.
  • Scraped content: content gathered from public websites.
  • Third-party material: content the company is not entitled to license.
  • Synthetic data: records generated by a model. A listing describes real records only.

Licence terms

Every dataset is licensed, not sold outright. The terms are agreed between the buyer and the company.

  • Exclusive or non-exclusive: a non-exclusive licence lets the company license the same data to others. An exclusive licence reserves it for one buyer, for a field of use or a set period.
  • Permitted use: training, fine-tuning, evaluation, retrieval and commercial deployment, each named separately.
  • Models and outputs: models the buyer trains, and their outputs, belong to the buyer within the licence's limits.
  • Re-identification: a ban on any attempt to identify people.
  • Retention and deletion: how long copies may be kept, and what happens at the end of the term.

Questions

What is an AI training data marketplace?

It is a place where companies license datasets to model builders for AI training. This marketplace lists company records, each cleared for rights and privacy before listing.

What kind of data is listed?

Communications, documents, workflow records and structured data that companies create in the course of their work. None of it is gathered from the public web.

Is every dataset cleared?

Yes. A dataset is listed only once it has a clearance record under the Buckingham Data Clearance Standard.

Is the company named in a listing?

No. A listing describes the dataset and its clearance. The company's name is disclosed to a buyer only when the company agrees.

Can we test a sample before we license a dataset?

Yes. A representative sample is delivered first, with its data sheet, and tested against your acceptance criteria.

Can we ask for data that is not listed?

Yes. Send a specification, and we approach companies that hold suitable records and clear a dataset to order.

Who can list a dataset?

A company that owns or controls the records, or a broker acting for one, once the dataset has been cleared.

Are datasets sold or licensed?

Licensed. The company keeps ownership of its records, and the licence gives the buyer permission to use a copy for the purposes it names.

Can a licence be exclusive?

Yes, for a field of use or a set period. Exclusivity is checked against earlier licences before it is offered.
