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.
RudderStack
RudderStack is a warehouse-first customer data platform designed to help you take control of your customer data without sacrificing security. Instead of storing your data in a third-party silo, it turns your existing data warehouse into a fully functional CDP. You can collect events from your web, mobile, and server-side applications and route them to over 150 different marketing, sales, and analytics tools in real-time.
You can also use its Reverse ETL capabilities to sync enriched data from your warehouse back into your operational tools. This ensures your entire team works with the same updated customer profiles. Because it is open-source at its core, you get the flexibility to customize your data pipelines while ensuring compliance with strict data residency and privacy regulations like GDPR and CCPA.
