Where to sell data to AI labs

Highford is a listings site. A data owner can post a dataset listing. An AI lab can search that listing and, with an account, unlock the contact and ask for an introduction. The site does not host the file, sell the file, or complete a license.

What you can list

A listing describes a dataset: the kind of data, the size, the rights the owner says they hold, whether it contains personal information, and whether a sample exists. The public card does not include the file or the owner's email.

The person who lists attests that they hold the rights and that the data was lawfully collected. Highford does not sell, host, or transfer the data, and does not verify rights.

What happens after you list

The listing stays a private draft until you confirm it. After that, it can appear in search. A lab that wants to talk uses a monthly unlock, then a credit, to see the contact name and email. A separate outreach step previews an email and sends it only after the sender confirms. The first intros each month are included. A reply is not guaranteed.

Labs can also post a data request that describes what they want. An owner can reply to a live request. The requester's email stays off the public card.

What this site does not do

Highford is not a data broker. It does not set a price, negotiate a license, verify that the owner holds the rights, or promise that a lab will respond.

Questions

Can I sell a dataset directly on this site?

No. You can list it. The file stays with you. A lab reaches you by unlocking the contact or by answering a data request.

Does listing guarantee a buyer?

No. A listing makes the description searchable. It does not promise a view, an unlock, or a license.

The same page as markdown, plus the API and MCP calls that belong to it.

API

Search listings

GET /api/v1/listings?q=support+ticket+archive

Skill file

GET /skill.md

Create a free account
