Prompt
Over the last 50 qualified opportunities at our building management software company, 28 prospects ghosted after proposal delivery. Our VP of Sales wants to initiate an aggressive discount campaign to re-engage them. How should we evaluate this pattern?

B2B Trust Engineering
Use this skill when qualified buyers engage but do not take action. The goal is
to make the buying decision feel safe by reducing risk, increasing relevant
proof, and making next steps obvious.
Source Traceability
Primary source: Unf*ck Your Sales by Jakob Greenfeld, especially the "Trust",
"Diagnostics", "The Confidence Fallacy", "The Persuasion Fallacy", "The Best
Option Fallacy", "The 7-11-4 Law", and "Engineering Trust" sections.
Diagnostic Signals
Trust is likely the constraint when:
Qualified buyers book calls, request proposals, or start trials but do not
close.
Prospects say the offer sounds good and then vanish.
The buyer appears to need the outcome but still chooses an incumbent or no
decision.
The pitch relies on confidence, vision, or ROI claims without enough proof.
The sales call tries to persuade instead of confirming what the buyer already
believes.
Trust Check
Review the last 50 qualified opportunities where possible:
How many closed?
How many ghosted after meaningful engagement?
How many stalled after a proposal or trial?
What proof did buyers see before the call?
What risks, ambiguities, or next-step friction remained?
If qualified close rate is weak or ghosting is high after engagement, treat
trust as the likely constraint.
