Private beta — marketplace intelligence
See where your marketplace margin is going.
saint brings pricing, Buy Box and competitor signals into one focused operating view, so sellers can see what changed, what it appears to cost, and what deserves attention next.
The problem
Margin rarely disappears in one moment. It drains.
Margin leaks quietly
Fee changes, returns and small price moves compound across SKUs long before they surface in a monthly report.
Buy Box shifts go unseen
A lost Buy Box can hold for days. By the time someone notices, the sales gap is already written.
Signals live in too many tabs
Seller Central, spreadsheets and manual price checks each hold part of the picture. None of them hold the decision.
Scope
What saint is, and what it is not.
A narrow product does one job well. saint is a decision layer, and we would rather be clear about the edges.
saint is
- A decision layer for marketplace sellers
- One view of pricing, Buy Box and margin pressure
- Built around your own cost and fee assumptions
- Deliberately narrow, and in private beta
saint is not
- Not an automated repricer
- Not an ERP or inventory system
- Not a generic chatbot bolted onto a dashboard
- Not a live product you can buy today
How saint works
One workspace, three deliberate steps.
- 01
Connect your catalogue
Bring in the SKUs you actually care about, with your own cost and fee assumptions.
- 02
Watch the pressure points
saint follows price movement, Buy Box state and margin exposure against those assumptions.
- 03
Decide what happens next
One ordered view of what changed, what it appears to cost, and the move worth considering today.
