A Founder's Guide to Evaluating AI Vendors (Without a Technical Background)
You don't need to understand transformers to buy AI well. You need six questions and the discipline to walk away when they aren't answered.

AI vendor pitches are engineered to make non-technical buyers feel behind. The demo dazzles, the case studies glow, and somewhere in the third meeting you're nodding at the word "agentic" while privately wondering what you're agreeing to.
Here is the reassuring truth: evaluating AI vendors is a business skill, not a technical one. These six questions do most of the work.
1. "What happens when it's wrong?"
Every AI system makes mistakes. Serious vendors describe their error rates, the review workflow, and the failure modes openly. Vendors who answer "it's very accurate" are telling you they haven't measured — or won't say.
2. "Show me a customer like us"
Not a logo wall. A reference customer of your size, in a comparable industry, using the feature you're buying, whom you may call. One honest reference beats forty logos.
3. "Where does our data go?"
You need plain-language answers: where it's stored, whether it trains their models, who can access it, and what happens on contract end. If the answer requires a follow-up call with a solutions architect, the product team hasn't made data handling a priority.
4. "What does implementation actually require from us?"
The demo runs on their data. Your rollout runs on yours — with your messy folder structure and your busy staff. Ask for the implementation plan in hours of your team's time. Double it. Still worth it? Proceed.
5. "What does success cost in year two?"
Per-seat prices, usage fees, integration maintenance. AI pricing models shift; model the renewal, not just the pilot.
6. "Can we leave?"
Export formats, data deletion, contract terms. The easier the exit, the more confident the vendor is in their product — lock-in is what replaces retention when quality can't.
The walk-away discipline
None of these questions require technical knowledge. They require the willingness to look unimpressed while a good demo plays. If a vendor can't answer two or more plainly, the product may be fine — but the partnership won't be.
