24/7Eyes on your sellers

Everyone's buying the same leads. You're guessing at the rest.

Bulk scanners dump the same 10,000 ASINs on every seller, then tell you to undercut. Meanwhile the storefronts that actually print money restock while you sleep. That is not sourcing. That is a race to the bottom with extra steps.

Without stalker
  • Scroll Keepa charts until your eyes cross
  • Pay for 10,000 junk leads every other seller also gets
  • Miss the 15-minute window when a winner restocks
  • Run five tools and still source blind
  • Source ten products, sell two
With Arbitrage Stalker
  • Let proven sellers do the research for you
  • Track only catalogs that already make money
  • Get pinged the second a winner restocks
  • One brain scores it all against your numbers
  • Your finds stay yours, capped so they stay profitable

Five tools' worth of signal. One brain.

Storefront stalking, Keepa Product Finder, restock monitoring, and curated lead banks all feed one engine. It scores every find against your real numbers and sends one alert where you already work. Stop running five tabs and missing the window anyway.

Keepa searches on autopilot

Paste a Keepa Product Finder URL. We run it on schedule and alert only on new matches, not the same 800 listings every day.

Chrome extension

One-click add any seller's storefront to your tracker, straight from the Amazon page. No copy-paste, no tab-juggling.

Seller scorecard

Which sellers are actually worth stalking? Avg BSR, catalog churn, replenishment velocity, ranked so you focus on the real winners.

Sub-90s response time

Priority scans on your high-value stores. When a hot product restocks, you know before the next 10 sellers do.

Three steps. Then it runs without you.

01
Step 1

Point it at your sources

Add storefronts with the Chrome extension, paste your Keepa Product Finder URLs, drop in restock ASINs. Every signal in one place.

Source what pings

Discord goes off. A restock means it makes money. Click, source, repeat. That's the whole game.

If you source on Amazon, this is your unfair advantage.

Arbitrage Stalker isn't another scanner. It's the nervous system for your sourcing: every signal you have, in one brain that tells you what to buy.

  • You run Amazon online arbitrage (OA) and are tired of junk leads
  • You do wholesale and want to spy on which brands to chase
  • You manage a sourcing team and need a single signal they all trust
  • You're tired of paying $80/mo for a scanner that surfaces the same 200 ASINs
  • You've scaled past six figures and want to 10x without 10x'ing the hours

Sellers are already finding leads with it.

Unprompted, on live calls. Real Amazon sellers in the community, in their own words.

I've been using Arbitrage Stalker a lot lately. I got one storefront in there and, oh my god, it's just a gold mine.

I've used Arbitrage Stalker with a retail monitor and found a couple of items I hadn't looked at before. There were some nice leads. So I'm happy.
