Proof
Creator-marketing attribution

Prove a creator actually sold something.

Give each creator one tracked link and code. Proof attributes the real sales back to them and shows you the ROAS — honestly, whether it worked or not.

How it works

1
Create a campaign
One creator, one fee. Get a unique tracked link and discount code.
2
Attribute automatically
Shopify webhook, a lightweight pixel, or manual entry — sales tie back to the creator.
3
See the honest ROAS
Revenue ÷ fee, cost per customer, and a plain read on whether it paid off.

A losing campaign looks like a loss.

Proof won't dress up a bad result. If a creator's ROAS is under 1, you'll see it in red — because knowing what didn't work is the whole point.
