Dewey (deweydata.io)

Dewey (deweydata.io) — A licensing and access platform for commercial proprietary datasets redistributed to academic institutions under DOI-versioned records — the accessible asset is the curated catalogue plus the research-ready copies it holds of partner data. Flagship holding is a large consumer card-transaction panel from a partner provider: 100M+ credit/debit cards (35M+ active in the last 12 months, 14M+ monthly active), online/offline/third-party spend across 13,000+ merchants and 800+ parent companies, tagged to public tickers, with demographic, geographic and behavioural breakouts an…

Dewey (deweydata.io) offers (Reference, Alternative, Fundamental) — Catalogue rather than a single store: the flagship partner dataset alone spans 100M+ cards and 13,000+ merchants with records reaching back to January 2014, and the platform holds multiple further US datasets from that provider plus additional partner sources (foot traffic, web traffic, social sentiment). Volume of the accessible holdings is therefore very large, but partitioned per-provider under separate licence terms rather than pooled..

Primary route to commercially-licensed consumer transaction, foot-traffic and web-behaviour data for model validation and academic benchmarking without negotiating a direct enterprise alt-data contract; a complete, versioned index of which proprietary datasets exist, who supplies them and under what licence terms — directly useful as a procurement and market-intelligence map; DOI-to-publication lineage for tracing which datasets produced which published findings (a scarce provenance signal for evaluating third-party model claims); and a reference collection of merchant-attributed spend, foot-traffic and sentiment panels for cross-validating in-house inference.

Coverage spans US; Financial Exchanges & Data, Education Services, Data Processing & Outsourced Services; reference, alternative, fundamental; equities.
