Funnel Diagnostic Interview — Find the Real Bottleneck in 12 Questions

Intermediate ChatGPT, Claude May 06, 2026

A structured self-interview that walks you through your own funnel, layer by layer, and surfaces where the leak actually is. Built from the same diagnostic I run on every Strategy Call — but you can run it on yourself first.

What this fixes

Founders feel the funnel is broken but can't name where. They optimize the loud layer (usually ads) because that's the layer with dashboards. The quiet layers — qualification, follow-up timing, proposal-to-close gap — leak more revenue but get ignored because nobody's measuring them.

How and why it works

The prompt acts as a structured interviewer, not a brainstormer. It walks the funnel in reverse — from closed deals back to first touch — asking quantitative questions at each stage (drop-off rate, time-in-stage, hand-off integrity). It refuses to move forward until you give a number or admit you don't have one. The 'I don't have one' answers are the diagnosis.

What to expect when you run it

A ranked list of funnel leaks with the missing measurements named. Most users find the bottleneck is two layers downstream of where they thought it was. This is the same exercise that opens every paid engagement — running it free is the point.
