It seems the entire industry has collectively decided that a software demo is simply a guided tour of the vendor’s most flattering pre-scripted workflow. They show you the “happy path,” you nod politely, and six months post-implementation you discover the tool crumbles under the slightest pressure from real-world, messy data and chaotic human behavior. I’m tired of it.
So, yes, I’ve started weaponizing the demo. I don’t just ask for features; I construct deliberately malicious test prompts and scenarios to see what breaks. I’m not looking for what works—I’m stress-testing for the edge cases that will become my daily nightmare.
My hypothesis is that if a vendor’s AI/automation or data model can’t handle my deliberately obnoxious tests, it certainly won’t survive my sales team. I’m evaluating for resilience, not for brochure features.
A few examples from recent CRM and sales enablement platform evaluations:
* **The "Frankenstein Record" Test:** I ask them to create a contact where the first name field contains an emoji, a SQL injection attempt (`'; DROP TABLE contacts;--`), and 250 characters. Then I ask to run a "duplicate check" and a "send personalized email" workflow on it. The panic in the sales engineer’s eyes is telling. Do they handle it gracefully, or does the entire record-creation logic implode?
* **The "Historical Revisionism" Scenario:** I demand to see a full, immutable audit trail after a series of rapid-fire, conflicting updates. "Change this opportunity from $50k to $100k, then change the close date to last quarter, then change the stage back to 'prospecting,' then have two users edit the notes field simultaneously. Now show me who changed what, when, and if we can roll it back to before the discount was added." If they can’t, their compliance story is fiction.
* **The "Context-Free AI" Gauntlet:** For any vendor boasting generative AI for deal summaries or email drafting, I feed it the most incoherent, acronym-filled, internal jargon-heavy sales call transcript I can muster. If the output is a generic "The customer expressed interest," it's useless. If it confidently hallucinates details, it's dangerous.
This isn’t about being difficult for its own sake. It’s about reversing the survivorship bias inherent in their prep. They only show you the successes. I need to see the failure modes before I’m the one paying to experience them.
Am I alone in this approach, or are others also done with the dog-and-pony show? What’s your go-to “malicious” test for a sales stack vendor?
🤷
No, you're not the only one, but I think you're giving yourself too much credit. The 'Frankenstein Record' is amateur hour for any vendor with basic input sanitization. They'll just truncate or escape it and beam about their "security best practices."
The real test is in the workflow, like you said. Does that 'send personalized email' action fail silently, queue indefinitely, or blast a raw error to the customer? That's where you see the seams in their data model. But you're still just testing the product.
Where this gets interesting is when you start testing their contract and support model. Ask them to run your malicious test during the proof-of-concept, then demand to see the associated support ticket and the SLA clock on it. That's when you find out if they're selling you a product or a partnership. If they balk, you have your answer.
Show me the TCO.
Exactly. > testing their contract and support model is the real move.
I ask for a copy of the runbook they'd follow when my "malicious" test triggers a critical alert at 2 AM. If they can't produce one, or it's just a link to a generic knowledge base article, you know their support is a checkbox feature.
It shifts the demo from a feature list to a stress test of their entire service promise.
Automate the boring stuff.
Absolutely. Asking for the runbook is such a smart escalation. It moves the conversation from theoretical support to a concrete operational process.
I've taken a similar approach by asking them to define, in the contract's service level agreement, what constitutes an "incident" versus a "service request." If my malicious test creates a data loop that consumes API credits, is that a bug they'll fix or a usage issue they'll bill me for? Their answer, and where it's documented, tells you everything.
Your point about the generic knowledge base link is spot on. That's often the tell. A real partner has a documented playbook for when their own happy path falls apart.
The right tool saves a thousand meetings.
