FullContact is a technology company that provides data enrichment and identity resolution services for developers and businesses. It offers APIs and software tools to enrich consumer profiles with social handles, bio data, firmographic information, and other publicly available signals, enabling workflows in marketing, sales, and customer relationship management.

Founded in 2010, FullContact operates a platform that aggregates data from public sources, licensed providers, and partner integrations to create enriched person and company profiles. The product lineup includes a person API for profile enrichment, a company API for business data, and features such as deduplication, contact verification, and audience enrichment. The services are designed to integrate with CRM systems, email marketing platforms, and other applications used for lead generation and segmentation.

Data and privacy: FullContact states that it supports data governance and compliance with privacy laws such as the EU General Data Protection Regulation and the California Consumer Privacy Act. Data may come from public records, licensed data providers, and user-contributed inputs, with opt-out mechanisms for individuals and customers who do not want their data used. Users of the API are responsible for ensuring lawful and consent-compliant use of data in their own applications.

Reception and market: FullContact is one of several major players in the contact enrichment field, alongside competitors such as Clearbit and ZoomInfo. It is used by developers, marketers, and sales teams to augment contact records, unify identities, and improve targeting and personalization. Privacy and data quality considerations remain central to its deployment in enterprise environments.
