Never Train Your Rival's Model

By Jon Nordmark — Co-founder & CEO, Iterate.ai; Founder & former CEO, eBags

Your files teach an AI how your business works. So does the way you work with AI — your prompts, patterns, and timing.

What you'll learn
Why your files, and the way you work with them, are the real asset for an AI vendor
Who benefits when your knowledge goes into a shared model
Three rules to hold to before you hand anything to an AI vendor

It starts with your files

Every company keeps records: Claims, contracts, repair logs, Notes. They look boring. They are not.

Those files show how your company handles things. Which supplier failed you. Why you wrote off that account.

But the files are only half of it. The other half is how you work with AI: the order you do things in, the checks you run, the calls you make when the output doesn't match expectation. AI learns from all of it.

Shared model:
your knowledge leaves
Your files and how you work
A model everyone shares
Your rivals The model itself

Two parties gain from your institutional knowledge. The second is the one that is new: the model's maker can enter your market.

vs
Your own model:
your knowledge stays
Your files and how you work
A model you own
You alone

One party gains: you. Every prompt improves institutional knowledge, efficiency, and insights.

What actually leaks

People picture documents leaving. That is only part of it. Three things teach a model. The last matters most:

Your files: the records themselves. This is data, but not learning.
Your workflows: the steps your team takes, in order, to get something done. This helps the AI learn.
Your corrections: every time someone tells the AI it got something wrong. That fix carries a piece of how your business really works. This is the most insightful thing a shared AI picks up about your business.
You essentially pay for intelligence twice, once with money, and again with the expertise you use to make it useful.

Satya Nadella, Chairman and CEO of Microsoft, calls this “intelligence exhaust” — the agent trail left behind from prompting and re-prompting or query correction.

When the platform becomes the competitor

eBags packing cubesI learned this lesson at eBags.com, years before AI. As one of the early companies selling through Amazon Marketplace, we sold about 300,000 packing cubes a year on Amazon. Amazon could see what customers bought, which colors and sizes became best sellers, and which prices and discounts worked best. Then AmazonBasics launched packing cubes that closely copied ours — down to the zipper styles and curved accent panels — sold them for less, and used our own product pages to cross-sell theirs. We sent a cease-and-desist. Amazon pulled them, then relaunched a slightly modified version within months.

The lesson is structural: when a platform can see what works, it can become your competitor. With shared AI, it can see something even more valuable — how your company thinks and works.

Three rules to hold

Rule 1 · Own it

The model runs on machines you control, and you keep the learnings.

Rule 2 · Never shared

What your company knows, never leverages a model your rivals already use – not your data, work patterns, or anything your AI built.

Rule 3 · Never an AI rival

Assume the vendor could one day sell what you sell. Ask whether you would still hand it your playbook.

Asking a vendor not to train on your data is the right move, but that clause is narrower than most buyers assume. See the companion brief, “Your Data Doesn't Train Our Model.” Technically.
