Who buys AI training data, and what each one publishes.
Much of what AI labs spend on outside data reaches the companies that hold it through vendors that buy for their own account and resell. Around them sit marketplaces that pay a share of each sale, intermediaries, wind-down services and programmes that pay for work to order. These 37, across 5 kinds, publish a way in. Open any one for its terms, in its own words.

- Not offers.
- A published rule is not an offer: each buyer evaluates the data before it names a price. None of these buyers is our client, and we are not the agent, partner or representative of any of them.
- Introduction fees.
- Several buyers pay whoever introduces a holder. In a sale we run we decline that money, tell you beside each offer what that buyer pays introducers where it publishes it or tells us, and ask it to put that amount into your price instead. If you choose instead to apply to one buyer through its own referral programme, that buyer pays us its published payout as well as our fee, and you see the amount in writing before you choose. An opened row says what each pays.
- Not listed.
- The AI labs themselves. They license data directly, and most publish no price or policy on brokers, so they are approached through a named role, first with a description that does not name the holder, then with the datasheet the holder approved. Vendors that say they buy data but publish no programme are on the vendor register.
The same data, shown to one buyer, gets one price.
Many of these buyers resell what they buy. One was reported to earn gross margins as high as 80 to 90 percent on off-the-shelf datasets it resells, and another says it will beat a qualifying written offer for the same data and rights, which shows how far apart their prices can be.
A holder that answers the first email sees one number. A holder that puts the same datasheet in front of several buyers at once, with its rights file ready, can compare their offers. Going direct, or through us: what each costs you.
