Stop Ranking AI Agent Vendors By Feature Count

The RFP spreadsheet lands in your inbox. Twenty vendors down one axis. Forty features across the top. Green checks and red X marks. You total the greens and pick the top three.

You just optimized for the wrong thing.

Feature count is the AI equivalent of buying a car by counting the cupholders. It tells you what the sales team put on the datasheet. It tells you nothing about whether the thing will do useful work on your business next Tuesday.

#Why the feature-count trap keeps working

Vendors know how buyers make lists. They ship a "Slack integration," a "CRM integration," a "voice mode," a "browser mode," a "custom knowledge base," a "workflow builder." Every box gets a check. The demo shows each one for ninety seconds. Nothing runs long enough to break.

Then you buy it. The Slack integration only fires on messages that mention the bot by name. The CRM integration reads records but cannot update them. Voice mode works in the demo language and nowhere else. The workflow builder is a UI over a queue that swallows errors silently.

You did not buy features. You bought icons on a marketing page.

#What actually predicts a good agent

Four things. None of them fit neatly in a checkbox.

#1. Task accuracy on your data, over a week

Not "in a demo." Not "on curated examples." Give the vendor twenty real cases from your own workload. Ask them to run the agent for five business days. Then read every single output. Count how many needed correction, how many were flat wrong, and how many the agent quietly gave up on.

If a vendor will not let you run this test, that is your answer.

#2. What happens when something breaks

Every agent fails. The question is what happens next. Does the failure show up in a log you can open? Is the failing run replayable so you can see the exact inputs? Can a support engineer explain why it failed by looking at the trace, or do they say "the model was probably having a bad day"?

Ask to see one real failure from another customer. Redacted is fine. If they cannot show you one, they are not looking at their own failures.

#3. Who owns the prompts, the data, and the workflow

Read the contract. Not the marketing page. The contract.

• If you leave, do you get an export of your prompts, your evaluation data, and your workflow definitions in a format you can actually reuse?
• If they change their model provider next quarter and your accuracy drops, is that your problem or theirs?
• Who owns the fine-tunes trained on your data?

A vendor that answers all three cleanly has thought about the future. A vendor that hedges is telling you they will lock you in the moment they can.

#4. How fast they ship for a real customer

Ask for two references. Not their biggest logo. A customer roughly your size, in roughly your industry, that has been live for at least six months. Ask that customer one question:

"When you asked for a change, how long did it take?"

If the answer is "we filed a ticket and never heard back," you now know how your first change request will go.

#The four questions that beat any feature checklist

Use these on your next vendor call. Watch how quickly the tone changes.

1. Can we run your agent on twenty of our real cases for a week before we sign?
2. Show me a real failure from a real customer, and walk me through how you diagnosed it.
3. If we leave in eighteen months, what exactly do we get to take with us?
4. Give me a reference roughly our size, and let me ask them one thing.

The vendors that answer these directly are the ones worth a second meeting. The vendors that dodge are telling you what the next twelve months of the relationship will feel like.

#The uncomfortable truth about most RFP lists

The feature checklist is comfortable because it turns a judgment call into arithmetic. Nobody gets fired for picking the vendor with the most green checks. Nobody has to explain why they trusted their read on the founding team. Nobody has to admit that a smaller vendor with fewer features but faster iteration is the better bet.

But arithmetic is not how good decisions get made about a technology this new. The best AI agents in the wild right now are running fewer features than the marketing pages of their competitors and shipping fixes twice as fast.

Count the wrong thing, buy the wrong thing.
