FullContact

FullContact is a Denver-based identity resolution company that links multiple identifiers and contact fragments belonging to the same individual into a single unified customer record. Its offering is organized around three product areas: Identify, which recognizes visitors on a customer's website to generate leads; Resolve, which consolidates individual data fragments into dynamic unified customer records; and Enrich, which appends more than 900 unique data attributes to new and existing customer records.

The company positions identity resolution as the basis of a first-party data foundation, including as a source of truth for AI agents that need consistent customer information. For publishers, it converts anonymous website traffic into customer segments by connecting online and offline data, using 700+ behavioral insights and citing match rates of up to 85%. It emphasizes that consumer-brand deployments require no handling of personally identifiable information by the brand and that customers retain control of their own data.

Business model

FullContact sells identity resolution and data enrichment capabilities to business customers, engaging prospects through demo requests on its website; the site directs martech/adtech platforms, consumer brands, and publishers to product-specific offerings.
