Carbon Arc
Pay-per-use alternative data exchange mapped to a common entity ontology
Carbon Arc operates a New York marketplace that licenses real-world datasets, including card spending, foot traffic, web and app usage and supply-chain records, and maps them onto a single entity model. Investment firms, corporates and AI developers buy slices on a usage basis via app, API, MCP server or bulk files.
GAII take
Usage pricing lowers alt-data trial costs; scrutinise panel provenance, entity-mapping accuracy and licence terms for model training.
