This page is the operating system behind every Ryndix judgment—published so you can see the gates before you buy a work order. We sell verifiable decisions before inventory and ads burn cash. We do not log into Seller Central. We do not run your account.
Is this Amazon US demand pocket enterable on evidence—not vibes?
PASS
Demand, competitive structure, and entry friction are documented on the same constraint table; open “unknowns” are labeled; invest-or-stop is explicit.
FAIL
Top competitors are opaque, review/ad barriers unclear, or the niche only “looks big” without unit-level room after fees.
Stop: large inventory PO, brand registry spend tied to this SKU, paid launch creatives at scale. Allowed: more research, free tool checks, a narrower hypothesis.
GATE 02
Supply documents
Can a factory quote and document pack survive desk review before you lock a supplier?
PASS
Specs, MOQ, lead time, Incoterms, and certificate status are comparable across shortlisted suppliers; gaps are listed (P02-style).
FAIL
Quote-only PDFs, missing compliance path, MOQ that blows cash before proof, or “trust me” verbal terms.
ARTIFACT
Supplier comparison sheet (5–8 desk screen → 3 priority) — not a factory audit.
After COGS, Amazon fees, returns, and a sober ad assumption—does contribution still fund learning?
PASS
Pre-ad contribution and post-ad scenarios are numeric; ruling price shelf is named; “stop” is allowed when math fails (see Walking Pad demo).
FAIL
Margin only works at a fantasy ASP, ignores returns, or needs hero ACoS the category never shows.
ARTIFACT
Unit economics sheet + price-shelf note.
IF THE GATE FAILS
Stop: inventory scale-up and broad paid traffic. Allowed: redesign cost, reposition SKU, or kill the direction.
GATE 04
Compliance & listing evidence
Would this page and image set survive Amazon detail-page rules and category documentation checks before you buy traffic?
PASS
Title/bullets/images have no prohibited contact/claim patterns; required docs path is listed; free image-compliance / listing-score checks are green or explicitly remediated.
FAIL
Main-image text risk, incomplete buying context, or missing cert path that can trigger suppression.
Is this a guarantee I will make sales or hit page one?
No. Ryndix sells judgments and plans with stated facts, assumptions, and limits. We do not guarantee sales, rank, profit, or success rate.
Do you log into my Seller Central or run ads for me?
No. No Seller Central login, no managed operations. You (or your team) execute; we deliver the decision artifacts.
How is a case study different from a client result?
Public category reviews apply the same gates to live marketplace data to show the method. They are labeled method demos—not testimonials and not your future outcome.
I already have a live ASIN. Where do I start?
Start at Gate 04 with free tools, then S01 ($199) for priority issues and invest-or-stop. Use P01 only when selecting or reshaping a direction from scratch.
Why ninety days instead of a twelve-month roadmap?
Ryndix scope is closing expensive mistakes before burn. Ninety days is enough to validate, land evidence, and plan capped tests—without pretending we operate your brand for a year.
