Segment is the world's leading Customer Data Platform (CDP), enabling companies to collect customer event data once and route it to any analytics, marketing, or data warehouse tool in their stack. By placing a single Segment tracking snippet on a website or app, teams can send the same customer events to Google Analytics, Mixpanel, Salesforce, Braze, Amplitude, and 450+ other destinations without separate integrations. Acquired by Twilio in 2020, Segment is the standard CDP for data-driven product and marketing teams.

The verdict
Our take on Segment
Segment is the right foundation for any company building a modern data stack. If you use 3 or more analytics or marketing tools, the investment in Segment pays back immediately through reduced instrumentation time and consistent data across tools. The free plan is limited; the Team plan at $120/month is the right entry point for growing startups.
