Overview

FullContact is an identity resolution platform that helps businesses recognize real people across devices and channels by connecting fragmented identifiers into a persistent, portable PersonID. The platform offers products for identity resolution (Resolve), data enrichment (Enrich), website visitor identification (Acumen Lead Identification), and secure data management (Identity Streme). FullContact's privacy-first approach enables real-time customer recognition without commingling data, supporting personalized marketing, sales outreach, and omnichannel experiences while maintaining compliance with privacy regulations.

Key Features

Identity Resolution (Resolve)

Maps fragmented customer data to a single, dynamic customer profile using a persistent, portable PersonID that works across devices and channels without commingling data.

Data Enrichment (Enrich)

Transforms a single identifier (email, phone, name/address, MAID) into comprehensive person-level insights including incremental identities, personal and professional information, delivered via real-time API or batch.

Website Visitor Identification (Acumen)

Identifies 100+ leads with professional email addresses within the first week for average customers, recognizing 45-70% of website visitors with browsing analytics, LinkedIn profiles, and real-time Slack alerts.

Secure Data Management (Identity Streme)

Flexible, encrypted private environment that ingests, obfuscates, and stores data with unique encryption keys, enabling secure data sharing with partners while maintaining privacy compliance and consent tracking.

Customer Recognition

Unifies anonymous and authenticated user data into a single record, identifying up to 80% more unauthenticated visitors and enabling personalized omnichannel experiences across media, websites, and platforms.

API Integration

Seamlessly integrates with CRMs, marketing platforms, CDPs, DMPs, and advertising networks via real-time API and JavaScript implementation for immediate data synchronization.
