MYSTERY CUSTOMER + EVIDENCE
Find where your company loses trust — before it loses the next customer.
We arrive as a real customer, try to understand, buy and solve a problem. Then we sit down with you and show what actually happened.
WHAT YOU RECEIVE
A clear map to understand, prioritize and act.
Where trust broke
The reproducible failure and its commercial or operational consequence.
What to fix first
Priority, recommended correction, suggested owner and retest.
NO MYSTERY
Four steps, from alignment to retesting.
You show us where it hurts
We align on the question that needs an answer.
We define the boundaries
Channels, identities, timing and allowed actions are recorded.
We walk the journey
People run the test; technology organizes the evidence.
We discuss the result
You understand what happened, the impact and the correction order.
FIRST REVIEW
Your first test starts free.
We walk one public journey and present up to three verifiable failures. The final conversation shows whether a broader scope makes sense.
