Segment CDP

Segment is a customer data platform (CDP) that acts as the central hub for customer data. On the input side, it collects events from websites, mobile apps, backend systems, and third-party tools. On the output side, it routes that unified data to 300+ destinations: analytics platforms, marketing automation tools, data warehouses, CRMs, and ad networks. Segment unifies customer profiles across touchpoints, creating a single view that powers personalization and activation. Segment's value is that you instrument your application once (send data to Segment), and Segment routes to all your tools. If you need to add a new tool later, you just connect it to Segment—no code changes required.
