An independent UK business, built around one Amazon problem
Packfox is independent Amazon brand protection: we watch the listings so the brands that own them stay in control of their own pages.
Why Packfox exists
Packfox didn’t begin as a brand-protection service. It began with me getting deep into how Amazon actually works, building my own tools on Amazon’s Selling Partner API to see what really happens on a product listing, beneath the surface a shopper sees.
The more I looked, the clearer one thing became: on Amazon, a brand’s own product page isn’t truly its own. Other sellers can attach their offers to it, the price can be pulled around, the buy box can pass to someone else, and the listing itself can be changed or suppressed. The brand is usually the last to know, often weeks later, when sales dip or a stockist complains.
I’d set out to work with brands on Amazon; what I came away with was something more useful to them: a way to catch those problems early and know what to do about each one. The tools to watch a channel properly exist, but they assume an analyst at the keyboard, and the agencies that offer real hand-holding charge thousands for it. Packfox is the part in between: the watching, the judgement and the legwork, done for you, at a price a smaller brand can actually justify.
Who’s behind it
I’m Martin Fox, and I run Packfox myself: one person wrote the rules your listings are judged against and stands behind every report, start to finish. I’m the sole director of Packfox Limited; you can check the company and my appointment on the Companies House register.
I’ve spent fifteen years in sales and customer service, across industries including insurance, retail and finance: detail-heavy work where being careful with the facts and straight with people isn’t optional. I’m not a developer by background; I learned to build the analysis tooling behind Packfox because I wanted to understand Amazon properly, rather than take a third-party dashboard’s word for it. Packfox runs on that mix of commercial instinct and tools I built and trust. The monitoring works around the clock in the cloud, every number in a report traces back to marketplace data captured on a stated date, and I answer for every report and draft that carries your name.
It’s the same instinct that shapes how Packfox handles your account: your marketplace data is used for one thing only, watching your own listings, and never shared or sold. The fee is a flat monthly one, not a percentage of your sales, so my only job is protecting your channel.
How we work
We buy specialist marketplace data; our sources include Keepa, an established provider whose price history data is used across the Amazon industry. When a client connects their own Amazon account, we add Amazon’s official Selling Partner API on top: signals from the account itself, such as offer changes as Amazon reports them, account health, listing suppression and content edits. What comes from your account and what we buy from the marketplace are kept separate in what we report. We use AI models to help draft what you read, and a person stays accountable for every word: each number in a report traces back to recorded evidence, and a figure that cannot be traced is not published. You could buy the same data yourself. What clients pay us for is the judgement and the finished next step, so none of it sits on your desk.
If you’d like to see what’s happening on your own listings, the free channel audit is the natural place to start: no call, no commitment.
