• 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.

• Genuinely self-serve — product managers build their own reports without help.
• Large free tier that carries an early-stage product a long way.
• Fast query performance on large event volumes.

• 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.

• Requires disciplined event instrumentation and naming.
• Weaker on user-level qualitative investigation than replay tools.
• Costs scale with event volume, which grows faster than user count.
