Affinity Solutions is a New York consumer purchase data and insights company that licenses bank-direct, permissioned credit and debit card transaction data covering 100M+ consumers and tens of billions of annual purchases. Its Comet platform turns that transaction feed into Consumer Purchase Insights, Consumer Purchase Lift, Consumer Purchase Audiences, Card-Linked Engagement and Consumer Bank Campaigns products for brands, media owners, retail and QSR, financial services and investors. Data is delivered through data clean rooms (AWS Clean Rooms), a Snowflake Native App on Snowflake Marketplace, managed services and aggregated-insight APIs rather than a public self-serve developer portal; no public API reference, OpenAPI description or SDK is published. The one machine-readable surface the company serves anonymously is an OAuth-protected Model Context Protocol server on its marketing site.
