How AI data brokers, marketplaces, human data vendors and direct deals differ for buyers and sellers, and which fits your data and situation.

Audience: Both

## In short

- A marketplace lists datasets for buyers to browse; a broker finds the right counterparty and helps structure a direct deal.
- Some data companies buy data and resell it to multiple AI developers, which means less visibility for the original holder.
- Brokers suit unique private data that needs rights work; marketplaces suit packaged datasets ready to sell.
- Ask any intermediary how it is paid, whether it holds copies of data, and who signs the license.

## Four routes

| Route | How it works | For sellers | For buyers |
| --- | --- | --- | --- |
| Marketplace | Seller lists, buyer browses and purchases | Reach, but often non-exclusive and price-led | Quick access to packaged data |
| Reseller or data vendor | Buys or licenses data, packages and resells | Simple, but data may reach many developers | One contract, less provenance visibility |
| Broker | Matches parties, supports a direct license | Control and visibility, fee on success | Access to unlisted data with provenance |
| Direct | Parties find each other | Full control, all the work | Full control, all the work |

## How we work

AI Data For Sale is a broker. We never take custody of raw data; samples and transfers move directly between the parties, and buyers and sellers sign the license directly with each other. Sellers pay a success fee only when a deal completes, agreed in writing before any introduction.

## Questions

### Why not just list data on a marketplace?

If your data is packaged, non-sensitive and broadly useful, a marketplace may suit you. Private company data usually needs rights work and buyer vetting first.
