FullContact

FullContact helps you solve the challenge of fragmented customer data by connecting disparate touchpoints into a single, verified person-level view. You can use their Identity Graph to map personal and professional identifiers—like emails, phone numbers, and social handles—to a persistent ResolveID. This allows you to recognize your customers across different channels even when they aren't logged in, ensuring your marketing messages remain consistent and relevant.

The platform is designed for mid-market and enterprise brands, agencies, and platform providers who need to enrich their first-party data. By integrating FullContact into your stack, you can improve lead scoring, personalize website experiences, and increase the accuracy of your measurement and attribution. It prioritizes privacy through a patented permission-based identity map, giving you a secure way to manage customer relationships without relying on third-party cookies.
