FullContact vs. Tie

FullContact is a privacy-safe Identity Resolution company building trust between people and brands. We deliver the capabilities needed to create tailored customer experiences, improve ad targeting along with measurement as well as improve identity verification and fraud solutions by unifying data and applying insights in the moments that matter.

Tie is the Shopper Intelligence Platform for B2C ecommerce, the AI data layer that recognizes who shoppers are, what they want, and when they're ready to engage. Built on a market-leading identity graph, Tie makes Klaviyo, Shopify, and the rest of the marketing stack smarter without replacing any of it. Volume-based retention marketing is breaking down. Inboxes are saturated, ESPs alone recognize less than 10% of website traffic, and past engagement is a poor predictor of what a shopper does next.
