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

• Retroactive event definition eliminates 'we didn't track that' entirely.
• Very fast time to first insight — no instrumentation project required.
• Warehouse sync for teams that want the raw data.

• 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.

• Autocaptured data needs governance or the event list becomes unusable noise.
• Session-based pricing on high-traffic products.
• Acquisition means overlap with Contentsquare's own products.
