// The Problem

The threat profile has changed.

The tools you have were built for humans committing fraud. They were not built for software pretending to be sellers.

⚡

AI agents create sellers at scale

What took hours of manual work in 2022 takes seconds today. LLM agents generate believable profiles, listings, and reviews automatically. The cost to create a convincing fake seller is near zero.

◎

Individual checks miss coordinated rings

Every tool you have checks one account at a time. Coordinated fake sellers only become visible when analyzing behavioral relationships across accounts, across time, across subnets.

↘

The cost compounds in silence

Promotional credits, fraudulent refunds, degraded buyer trust, regulatory exposure under DSA. Most marketplaces are losing 5–15% of promotional spend to synthetic sellers right now, without knowing it.

// How It Works

Three steps.
No integration required.

We designed the audit to be frictionless. Your engineer doesn't touch anything. You see the findings before committing to anything.

01

You export

Send us a CSV of recent seller signups — seller ID, timestamp, email, IP. Everything can be hashed before it leaves your system. We provide the exact SQL query to run. Takes 15 minutes on your end.

02

We analyze

Our engine runs burst detection, infrastructure clustering, email pattern analysis, and behavioral sequence comparison across your entire seller base simultaneously. No single account tells the story — the cluster does.

03

You get findings

48-hour turnaround. A forensic report showing every cluster found, attack patterns, estimated financial exposure, and why your current controls miss it. No integration. No commitment. Just evidence.

// Sample Findings

What we actually find.

Every audit is different. This is representative of what we surface in a mid-size consumer marketplace.
