Overview
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.
Twilio Segment
Twilio Segment helps you break down data silos by providing a single point of collection for all your customer interactions. Instead of writing custom code for every new tool you want to use, you integrate the Segment API once and then flip a switch to send that data to over 450 different applications. This ensures your marketing, product, and engineering teams are all looking at the same high-quality, real-time information.
You can use the platform to create a unified view of your customers across web, mobile, and server-side touchpoints. It allows you to enforce data governance, protect user privacy, and build personalized customer journeys at scale. Whether you are a startup looking to get your data stack right from day one or an enterprise managing complex global data flows, it provides the infrastructure to turn raw data into actionable insights.
