The Necrotic Mass in the Back Room (And the Bounty We’re Placing on It)

Let us consider the back room. Not the gleaming, track-lit showroom with its artisanal birchwood hangers and the faint, expensive scent of white tea and bergamot, no—we must speak of the back room. The purgatory of corrugated cardboard. The sunless, airless, fluorescent-flickering crypt where last season's delusions go to petrify. You can smell it, can't…

We Will Sell No Tech Before Its Time. RDE Prime launches in 45 days. The era of gut-feel retail is over.

If you know retail, you know the feeling. You look at your P&L at the end of the quarter, and it says you are profitable. You call your accountant, and they confirm it. You are a successful independent retailer. Then you log into your bank account. The FCF isn't there. Where did it go? It's sitting in your back room. It’s trapped in out-of-season coats,…

The Main Street Turnaround and CMP’s New Algorithmic Alliance

If you want to understand the real health of the American economy, don't look at the quarterly earnings of Amazon or Target. Look at the back rooms of independent retailers. Right now, there is a quiet crisis of trapped capital unfolding, billions of dollars tied up in dead inventory. For the owner-operator, the P&L might say they are profitable, but the…

I was talking to an investor who said, "John - if you want to get some attention, pick a fight."

Told him I already know who the fight is with, and why it puts CMP on the side of the angels. The fight is with BIG retail. As I've learned more about independent retailers, I've come to discover this: they are the backbone of a community. Not a metaphor. A fact you can trace, dollar by dollar, block by block. When Big Retail moves in and pushes them out,…

The Best of Times, the Worst of Times: We Are Handing Over Life to the Machine

We are, whether we've admitted it to ourselves yet, systematically handing over life to the AI machine. Not in some distant sci-fi sense. Right now, in 2026, in the granular decisions of hiring, firing, capital allocation, and how a small retailer in Ohio figures out what to do with a warehouse full of dead inventory. The handover is already well underway,…

CMP's Advisory Board - to a person (https://cashmarginpartners.com/board-of-advisors) - has continuously (and rightfully) - encouraged me to hyper-focus on a couple things. 100%. Nevertheless, this AI-stuff is nuts. The speed at which product can get built, launched, and marketed is breathtaking. It's business at the speed of thought. As a result, a rank…
