SSShelfSignal
Walmart Marketplace firstDemo dataset — no live marketplace connection

Know why a product is worth selling — and how much the evidence is worth.

ShelfSignal is a product intelligence workspace for Walmart Marketplace sellers. It turns market snapshots, supplier quotes and category trends into a defensible verdict: the unit economics, the risks, the conditions that would have to be true, and an honest grade on the data itself.

What a verdict looks like

Opportunity score

74

Demand, economics, competition, trend, supply and risk — weighted to your targets.

Data confidence

61

Demand is estimated from indirect signals; supplier quotes are 12 days old.

Provenance on every figure

OBSERVEDCALCULATEDESTIMATEDAI

Nothing is presented as fact unless it was actually observed.

Built to survive scrutiny

Sourcing decisions fail on hidden assumptions. Every screen here is designed to expose them.

Two scores, never blended
An opportunity score tells you how good the deal looks. A separate data-confidence score tells you how much the evidence behind it is worth.
Every number has a source
Each figure is tagged Observed, Calculated, Estimated or AI, with the formula or snapshot it came from — so you can argue with it.
Unit economics, not vibes
Landed cost, referral and fulfillment fees, storage, returns allowance and ad spend roll into a real per-unit P&L with break-even and ROI.
Risks stated plainly
Regulated, fragile, battery, brand-risk and thin-margin conditions are flagged with the reason, the evidence and a mitigation.
Predictions vs. actuals
Log what actually happened after a test order. ShelfSignal compares it against what it predicted and shows where the model was wrong.
Supplier reality check
MOQ, lead time, duties and packaging feed the same math, so an attractive margin never hides an unaffordable first order.

The validation path

  1. 01

    Set your economics

    Minimum margin, ROI, investment ceiling, MOQ and lead-time limits, ad spend.

  2. 02

    Run the funnel

    Candidates are screened stage by stage: economics, demand, competition, then risk.

  3. 03

    Interrogate the dossier

    P&L scenarios, sensitivity, competitor spread, supplier quotes, evidence ledger.

  4. 04

    Test and record

    Order a sample, log the actuals, and see how close the prediction really was.

33 Walmart-style products across eight categories, with eight months of history, competitor sets and supplier quotes — enough to exercise every calculation end to end.
