Training Data

A live map of the companies powering AI with data, generation, labelling and curation.

Funding is modest and almost entirely venture ($3.5bn of $3.7bn), striking for a layer every model depends on. The movement is upmarket: commodity labelling still leads (42 companies), but expert data and RL environments for frontier labs (29) are the fastest-emerging cluster, where value shifts from volume to expertise.

The map is one large image. On a small screen the list below is easier to read.
