Buy enterprise data for AI training: providers and provenance

Updated 2026-10-08

The provider you pick decides the provenance file your lawyers inherit.

Licensed corpora and marketplaces

5 providers on the board list licensed corpora as their main offer and 2 run a marketplace. Their sourcing column shows whether they name the rights-holders as the source.

Annotation and expert feedback

Of the providers the board reads as annotation or expert-feedback firms, Snorkel AI and Scale AI describe experts in the sourcing column, a workforce rather than a data source, while Surge AI's home page as read says nothing about sourcing. How the rights in what a workforce produces are held is a question for the buyer to put to the provider.

Describe the training data your team is buying
