The names cost one work email.

The figures above are yours to keep. Give us a work address and we'll unblur the seller aliases, their storefronts and their capture history.

See it.

A daily scan reads every offer on your listings and records the price, the seller, the storefront and who holds the Buy Box. Anyone not on your allow-list is reported as unauthorized.

Cost it.

Each violation is priced against your MAP and your demand signal, so what lands in your inbox is money rather than a count. Every figure shows the inputs that produced it.

Act on it.

Export a timestamped evidence pack and an escalating MAP notice addressed to the seller or the marketplace. You send it. We log the reply and keep watching the listing.

Every observation
is verifiable.

A capture is a rendered page, a timestamp and a SHA-256 digest of the record. Recompute the digest yourself — the number below is hashed in your browser, right now, from the record on the right.

We are not SOC 2 or ISO 27001 certified yet, and our security page says so plainly.

Radar, not
a retainer.

There are three ways to handle sellers who undercut you. This is what each one hands you at the end of the month.

Enforcement agency

Outsourced takedowns

$2k–$6k/mo, plus a fee per case

A monthly summary, not the listings.
Their crawl, on their schedule.
The evidence stays in their case file.
You hear what happened after it happened.

Price tracker

Charts, not sellers

Around $49/mo, self-serve

Prices, with no seller identity.
No allow-list, so nothing reads as unauthorized.
No MAP logic and no exposure model.
Nothing you could forward to counsel.

Tracewall

Radar and evidence

From $124/mo. The first scan needs no card.

Every offer on every listing, read daily.
Sellers named, then checked against your allow-list.
Money, with the inputs that produced it.
A timestamped pack and a notice — yours to send.

We don't file takedowns. When you want someone to, hire the agency and hand them the pack — that is what it is for.

See what's in a pack

See it on your listings.

We're early, so we'd rather show you the method than a wall of borrowed logos. Every figure prints its inputs, every capture is yours to re-hash, and the first scan runs on your own catalogue — free.

Why we built it

Brands lose margin to sellers advertising under MAP, and most tools tell you a violation exists without telling you what it costs — or who is behind it. Tracewall answers both: it names the seller, prices the leak against your MAP, and hands you evidence you can act on.

The goal was never another dashboard. It's the one document you can forward to your channel lead, or your counsel, without editing it first.

See how it works

How the number is built

Revenue at risk is the estimated demand for a listing, times the share of offers coming from violating sellers, times the per-unit hit to your protected margin. No black box — every input is printed next to the figure, and each one is yours to edit.
