About us

Built for sellers on thinner margins. Brought to US brands.

Sapientia is an Amazon advertising audit from DAER LLC, New York. It was built for cross-border sellers running thousands of SKUs on ten-point margins. A tool survives there only if it finds money you can see.

How we work

Four things we won't compromise on.

01

Nothing changes until you approve it.

Every recommendation waits for a person. Delegation is granted by fix type, with an end date.

02

A projection is labeled a projection.

The number we keep is the seven-day re-measurement after each change.

03

No customer names without permission.

We’d rather show you a redacted report than a logo wall.

04

Flat pricing for brands.

A percentage of spend gives a vendor a reason to want you to spend more.
