# Introduction

> List and sell private data that AI labs train and evaluate on, or buy it.

**DataVendor** is HUD's marketplace for private AI training and evaluation data. Vendors list
assets they already hold: codebases, tasksets with the RL environments they run on, and Raw data.
Buyers, mostly AI labs, buy those listings, or post a request when the catalog does not have what
they need.

Every sale is between organizations, and vendors never learn which buyer bought. Vendors set their
own prices, buyers see quality evidence before they pay, and access to a purchase lasts after the
sale. [How DataVendor works](/overview/how-it-works) explains the model and the rules behind it.

DataVendor runs on the [HUD platform](https://docs.hud.ai). Tasksets and environments you sell or
buy are the same objects the platform runs evaluations against, and a HUD team API key works with
the DataVendor [APIs](/overview/api) too.
