Analytics & Product Signals
2 tools reviewed with honest assessments, pricing breakdowns, and GTM Engineer use cases.
Analytics tools track what users do inside your product. For GTM Engineers, this data feeds directly into outbound targeting. A user who visited the pricing page three times this week is a hotter lead than someone who signed up six months ago and never came back. Product signals turn usage data into pipeline.
Segment is the customer data platform (CDP) that routes events to every downstream tool. PostHog is the open-source product analytics platform that gives you session replay, feature flags, and event tracking without per-seat pricing. Both serve different roles in the GTM stack, and many teams use them together.
GTM Engineers care about analytics tools primarily as data sources, not dashboards. The key evaluation criteria: can you trigger workflows from product events? Can you build user segments based on behavior and push them to your CRM or sequencing tool? Does the API let you pull usage data into Clay or n8n? If the answer to all three is yes, the tool earns its place in your stack.
