How it works

From follow to flip in three steps

01

Follow the sellers

Paste a storefront or seller ID. Doppio starts watching their inventory around the clock.

02

Doppio hunts

Every new listing is scored on live profitability signals and dropped into your ranked feed.

03

You flip the winners

Skim the top of the feed, approve the leads worth buying, and move them straight into your pipeline.

Features

Everything you need to out-source the competition

Effortless seller tracking

Follow any Amazon storefront once. Doppio watches every ASIN they add, drop, or reprice — so you never manually re-check a seller again.

Ranked by deal heat

New listings surface in a single feed, ranked by profitability signals. Your proven, followed sellers pin to the top automatically.

Seller score you can trust

A decayed hit-rate score tells you which storefronts actually produce winners — and quietly demotes the ones that have gone cold.

Brand mining

Found one winner? Open the brand view and mine every other ASIN that brand sells, heat-ranked and ready to source.

Snooze & blacklist

Kill the noise. Temporarily snooze a distraction or permanently blacklist a seller — your feed stays sharp and personal.

Built for your VAs

A clean lead → order → restock pipeline your team runs end to end, with admin-gated bulk actions on every list.

FAQ

Questions, answered

What exactly is a storefront stalker?

It's software that continuously watches the Amazon storefronts of other resellers. When a seller you follow lists a new product, Doppio catches it, scores it for profitability, and surfaces it to you — automatically.

How is this different from a manual check?

Manually re-visiting dozens of storefronts is slow and easy to abandon. Doppio watches every followed seller around the clock and only shows you what's worth your attention, ranked by deal heat.

Do I need my own Amazon Seller account?

Yes — Doppio is built for active Amazon resellers doing online arbitrage. You bring your sourcing hustle; Doppio brings the leads.

Can my virtual assistants use it?

Absolutely. Doppio runs a clean lead → order → restock pipeline with admin-gated bulk actions, so your VAs can run day-to-day sourcing while you keep control.

Is there a money-back guarantee?

Yes. If Doppio doesn't earn its keep in your first 30 days, we'll refund you — no hard feelings.

Monitor your favorite resellers

Stop refreshing storefronts by hand. Let Doppio do the stalking while you do the flipping.
