Illustrative result. Demand remains unverified until seller research is complete.
Built for scrutiny

Practical intelligence for operators.

Conservative economics

Fees, shipping, reserves, and costs are visible—not hidden behind a headline margin.

Matching transparency

See why marketplace evidence was accepted, rejected, or left unresolved.

Evidence visibility

Inspect comparable offers and freshness before making a sourcing decision.

No fake demand claims

Active asking prices are never presented as sales velocity or verified demand.

FAQ

Clear answers before you upload.

Does ProductGap guarantee profitable products?

No. Results are candidate opportunities for deeper research, not guaranteed outcomes.

Does active marketplace data prove demand?

No. Asking-price evidence helps evaluate economics and competition. Demand must be verified separately.

Can anyone create an account?

Not during the founding beta. Approved sellers receive an invitation and workspace membership.

What supplier files are supported?

CSV and XLSX catalogs with SKU, product, cost, stock, variant attributes, and GTIN where available.
