About
The largest AI newsletter for ecommerce sellers.
Cruxfinder helps Amazon, Shopify, TikTok Shop, and Walmart sellers cut through the noise with weekly news, free tools, and AI powered strategy breakdowns.
Our mission
Ecommerce moves fast. Marketplace policies change without warning, new AI tools launch every week, and staying current used to mean scrolling through a dozen different forums, newsletters, and seller groups just to catch the important updates.
Cruxfinder exists to fix that. We track every meaningful change across Amazon, Shopify, TikTok Shop, and Walmart, then turn it into clear, actionable coverage delivered every Monday. No fluff, no filler, just what sellers actually need to know to protect their margins and grow their business.
What we cover
Weekly Newsletter
Every Monday, we break down the most important marketplace news, policy changes, and AI tool launches into a fast, actionable read.
Free Tools
A growing library of free calculators and analyzers built specifically for Amazon, Shopify, and TikTok Shop sellers. No sign up required.
Software Directory
A curated directory of the tools and platforms ecommerce sellers actually use, covering research, PPC, listings, analytics, and more.
In Depth Guides
Practical, no fluff articles covering AI workflows, marketplace strategy, and platform specific tactics for sellers on every major channel.
Our approach
We read the source material so you do not have to. Every story we publish is grounded in official marketplace announcements, seller forum discussions, and firsthand testing of the tools and tactics we cover.
We are not afraid to point out when a policy change is confusing, when a new tool underdelivers, or when a marketplace update creates more problems than it solves. Sellers trust Cruxfinder because we call it like we see it.
Cruxfinder and AmazonRankPro
Cruxfinder is part of a small family of resources built for ecommerce sellers. AmazonRankPro, our sister brand, focuses on Amazon specific tools and partnerships. Together, these properties reach thousands of active sellers every week.
