In short

Dashboards show the week customers left, never the why. iMario walks the journey with them and brings back the reason, so you fix the cause, not the chart.

The problem

Live systems show behaviour, never reasons.

[1]
1 timestamp

Is what a churn event records. The step is measured to the second; the reason is not a field.

[2]
0 reasons

Come back from most of the people who leave. Nobody cancels, they just stop opening it, and the exit survey only reaches the few who bother.

[3]
1 quarter

Per hypothesis, because a week-3 test needs enough people to reach week 3 before it can call anything. A wrong guess costs the next one too.

How it works

Walk the journey with them, one step at a time.

Lay the flow out, send an audience through it, and hear at every step who is leaving and why. Then rerun the fix on the same people.

What you get

Fix the cause, not the chart.

Week three told me I was behind. I read it as being written off, not encouraged.

Left at week 3 · 62

A reason behind every drop

Each week of the curve opens into what people said as they left it, in their own words.

The fix, pre-tested

Rerun the rewritten step on the same cohort before a single real customer sees it.

81%

A journey you can rerun

The whole path stays as an asset, so next quarter’s change is measured against the same people.

Compared

Product analytics and a journey read, side by side.

Analytics is the right tool for what happened. This is the tool for why, and for testing the fix before the next cohort reaches the step.

Illustrative run · Health programme

The week-3 drop nobody could explain.

The message was rewritten and rerun on the same cohort. The curve held before the next intake started.

A twelve-week programme walked end to end by 600 synthetic patients, then the rewritten week rerun on the same cohort — one afternoon.

Where they were

A twelve-week health programme had lost people at week three for a year. Two fixes shipped against two hypotheses; the drop stayed.

Week 3

Where the notification read as being written off rather than encouraged.

58% of
over-60s

Read it that way, against 21% of under-45s — an age split no dashboard showed.
