How to Evaluate AI Vendors Without Sitting Through Sales Calls
If they can't answer in a shared doc, the answer is no. A practical scorecard for cutting through demos.
James had been through six AI vendor demos in three weeks. Each one was the same: polished slides, impressive benchmarks, enthusiastic account executives. Each one left him with the same question: what actually happens when we try to use this?
The seventh demo was different. The vendor responded to his questionnaire with written answers — detailed, specific, including references to their gaps. James spent 30 minutes reviewing their document instead of an hour on a sales call. That vendor earned a pilot. The other six, who wanted "a call to discuss," never got one.
Vendor evals devolve into slide decks and "we'll cover that in enterprise pricing." You don't need another hour of animated logos. You need evidence on integration, data handling, and what happens when you leave.
Scorecard categories
- Integration — APIs, SSO, audit logs, on-prem option — not roadmap promises, today's capabilities
- Data — training opt-out, deletion SLA, encryption at rest and in transit, region locks
- Exit — export formats, contract term, portability — what happens day one after cancellation
- Proof — reference customer in your industry, not a logo wall of companies that look like yours
Score on your workflows, not their benchmarks. Send a structured questionnaire before any call. Vendors who ghost or waffle just saved you budget. The ones who answer become your shortlist.
| Signal | Meaning |
|---|---|
| "Trust us on security" | No SOC2 / no DPA / no third-party audit |
| Vague on export | Lock-in by design — they know leaving hurts |
| Demo-only features | Roadmap sold as product — you're betting on promises |
| No industry reference | Logo wall of companies nothing like yours |
The Questionnaire They Can't Dodge
Send twelve questions in writing before booking a call. Data residency, training opt-out, deletion SLA, sub-processors, export format, on-prem option, audit log access, rate limits, incident history, termination data portability, pricing model at 10x volume, reference customer in your industry.
Vendors who answer thoroughly earn thirty minutes. Vendors who reply "let's discuss on a call" earn a pass. Sales calls optimize for emotion; written answers optimize for evidence. Your procurement team needs a paper trail, not charisma.
Score answers 1-5 with weighted categories. Integration and exit cost usually matter more than benchmark slides. If they won't put integration depth in writing, they don't have integration depth.
If they can't answer in a shared doc, the answer is no.
Comparing vendors to tools you can trial solo
Hold vendors to the bar set by focused utilities you spin up in minutes — clear scope, no sales engineer required, obvious value. Enterprise AI doesn't get a pass on friction because the logo is shiny. If a free tool explains budgets better than their demo, ask what you're paying for.
What this means for you: publish an internal scorecard template. Every eval uses the same weights. Decisions become comparable quarter to quarter — not amnesia with new slide decks. The best vendor meeting reviews their written answers, not discovers them live.
Vague on export or training on your data? Next vendor. No exceptions.
Reference calls that aren't marketing
Ask references: what broke in month two, what export hurt, what support ticket took longest. Happy references are fine; honest ones are gold. If vendor won't connect you with a customer who churned, note that too.
What this means for you: score references separately from questionnaire answers. A perfect PDF plus a lukewarm reference beats a vague PDF plus a logo wall. You're buying operations, not slides.
Contract clauses that matter
Negotiate data deletion timelines, training opt-out in writing, liability caps on bad outputs, and export assistance at termination. Verbal promises evaporate at renewal disputes.
What this means for you: legal reviews written questionnaire answers before pilot expands to prod. Sales agreed in email isn't enough — get it in the order form.
Build internal score history
Keep every vendor's written answers in a shared drive — compare year over year when they return with "we fixed that." Memory beats slides. Publish an internal scorecard template so every eval uses the same weights. Decisions become comparable quarter to quarter — not amnesia with new slide decks.
Pilot success criteria
Define pass/fail metrics before API keys land — accuracy on your eval set, p95 latency, export completed in under an hour. One workflow, two weeks, your data, your logs. The pilot ends with a scorecard, not a feelings meeting.
On day ten of the pilot, run the exit drill: export everything. Measure the pain. If the vendor's platform can't spit your data back out cleanly in under an hour, that's your answer.
Share the scorecard template internally before RFP season. Procurement, security, and engineering score the same columns — fewer surprises when legal joins week three. Archive every written response; revision history catches moving promises.
If they can't answer in a shared doc, the answer is no.
Twelve questions, one scorecard, zero slides
You don't need another animated-logo deck to know whether a vendor is worth your budget. You need their written answers on data residency, export, and what happens on day ten of the pilot. What this means for you: send the questionnaire before you book a single call. Vendors who answer earn thirty minutes; vendors who stall just saved you a procurement cycle.
Keep every written answer in the same shared drive, scored on the same weighted columns, year after year. That archive is worth more than any reference call — it's the paper trail that catches a vendor quietly walking back a promise at renewal.
