## Overview

Segment users have made a deliberate investment in customer data infrastructure — they're collecting structured event data, routing it to downstream tools, and building a foundation for personalization and analytics. Companies running Segment are among the most data-mature buyers in the market and are active evaluators of the downstream tools that consume and activate their customer data.

## What's Included

Confirmed Segment CDP installation data and company firmographics. The audience is concentrated among SaaS, fintech, and e-commerce companies with active product analytics and customer data programs.

## Use Cases

- **Data activation and reverse-ETL vendors** targeting companies with structured Segment event streams
- **Personalization and experimentation platforms** selling to companies with Segment as their data foundation
- **Competing CDP vendors** (RudderStack, mParticle) building displacement campaigns against Segment
