Mystery Collector
See your gallery through a collector’s eyes.

07 / Commercial perspective
What is one missed
opportunity worth?
How many additional sales would cover your program? See what the gallery’s commission on each sale could contribute.
A small number of additional sales can cover the investment in your team. Adjust the figures to see the threshold for your gallery.
When does the program pay for itself?
2 additional sales
$15,000 commission per sale · $30,000 across 2 sales covers a $20,000 program.
Illustrative inputs, not a fee quote. Calculated from gross gallery commission before other costs and taxes. These must also be covered to reach net break-even. Only additional sales count towards the illustration; sales outcomes are not guaranteed.
Sales training / Online & Inquiry Sales

to a confident purchase.
Turn digital inquiries into meaningful collector conversations—and sales.
Practical training to help your team respond effectively, build trust remotely and guide collectors toward a purchase through email and phone.
Make the first reply count.
Understand the inquiry and open a personal, relevant conversation.
Build trust at a distance.
Present artworks with confidence and lead effective phone conversations.
Follow through to the sale.
Address hesitations, sustain momentum and guide the next step.
Art fair support
Before. During. After.
A three-stage program to help your gallery make the most of every art fair.
From preparing your team to supporting collector conversations and following through after the fair, GPI provides practical support tailored to your gallery.
Prepare.
Align your team, artist presentations and collector appointments.
Connect.
Support your team on the floor with collector conversations and sales.
Follow through.
Turn new connections into personal follow-up and lasting relationships.
Scope agreed in advance. Independent advisory; no affiliation with fair organizers.
Confidentiality & discretion
Trust is part
of the method.
The purpose is to develop the team and improve the collector experience. A useful assessment should create clarity, not anxiety.
Confidentiality, access and the treatment of personal information are agreed in writing before an engagement begins.
Who sees the report?
The engagement defines the authorized recipients. An NDA can be put in place before any information is shared. Reports are not published or shared with other galleries.
Is the team informed?
We agree the communication approach with leadership in advance, including how the team is informed and how feedback is delivered. The program is designed for development, not public ranking or individual humiliation.
Who owns the data?
The engagement agreement provides for the gallery to own its engagement-specific observations and reports. GPI retains its pre-existing methodology. Access, retention and deletion arrangements are set out before work starts.
What about artists and collectors?
Scenarios assess the gallery experience, not the quality of an artist’s work. We minimize personal information, avoid collecting confidential collector records and do not make purchase commitments.
