Vendor demos are rigged, and it is not the vendor's fault

We have sat through a lot of vendor demos. Good ones, bad ones, ones that lasted two hours and should have lasted twenty minutes. After a while a pattern becomes obvious.

Every vendor demo runs on a rigged environment.

We do not mean rigged as in dishonest. We mean rigged as in set up in advance to make the product look its best. Clean tenants. Curated data. The three use cases the vendor already knows how to handle. A sales engineer who has practiced that exact flow thirty times this month.

That is not a conspiracy. That is what a demo is. A demo is a sales tool. The vendor is showing you what their product can do on its best day, at its best angle, against the data they picked.

The problem is not the demo. The problem is when you mistake the demo for an evaluation.

What the demo cannot show you

Your log volume at 3x projected growth. Your identity group structure with the one weird group nobody cleaned up in 2019. Your Kubernetes cluster with the one service emitting 40x the traffic of everything else. The integration point between the candidate product and the other tool you already run. The pricing curve when your usage crosses a tier break.

Those things live in your stack, not theirs. No demo touches them.

What to do instead

Run the evaluation inside your environment. Point the candidate at live data. Measure cost, coverage, latency, integration fit, and identity feasibility against what you actually run. Score candidates against each other on dimensions you picked, not dimensions their marketing picked.

If a vendor pushes back on evaluation against real data, that tells you something on its own.

The short version

Every vendor has a great demo. Every vendor has a product that breaks against somebody's stack. You are trying to find out whether their product breaks against yours.

The demo cannot answer that question. Only the evaluation can.
