Who hurts
Product and growth teams at seed-to-Series-B SaaS companies.
The problem
Funnel analytics say where users leave. Nobody has three hours to watch replays to learn why, so teams redesign steps based on opinion and the number doesn't move.
What you build
Detect the worst drop-off step automatically, pull the replays of sessions that failed there, and summarise the recurring cause — rage clicks on a disabled button, a form rejecting valid input, a verification email that lands after they gave up — with clips as evidence.
Why now
Replay tools expose event streams and DOM snapshots via API, and models can now read an interaction sequence and name the failure.
Validate it this week
Ask three founders for read-only access to their replay tool for one week and send them a one-page findings memo. Their reaction tells you whether it's a vitamin.
Why you'd keep winning
A library of named failure patterns that improves across customers while keeping each customer's data isolated.
The honest risk
PostHog or FullStory can ship this as a feature. Move fast, or aim at the teams whose replay tool won't build it.
The prompt is written to make an AI argue with you before it writes code — that first round of pushback is worth more than the scaffold.
