• The deepest retention and cohort analysis in mainstream product analytics.
• Good free tier for early-stage products.
• Strong data-governance tooling for event taxonomy.

• Statistics engine is genuinely strong — sequential testing and CUPED are not marketing veneer.
• Flags, experiments and analytics in one system removes a whole class of integration work.
• Warehouse-native mode satisfies data-governance requirements.

• Requires deliberate event instrumentation — nothing works without it.
• Enterprise pricing rises steeply with tracked users.
• Replay and experimentation are newer and less mature than the analytics core.

• Event-based pricing can escalate sharply on high-volume products.
• Broad surface area means a real learning curve.
• Now owned by OpenAI, which introduces strategic uncertainty for some buyers.
