The most important AI vendor evaluation question is the simplest one: where does my data go? Evaluate AI vendors on their data practices, their model performance on your data, and their pricing model. Ask where your data goes, how it is used, and whether it trains their model. Get the data terms in writing, test the model on your inputs, and read the pricing page twice.
Evaluate AI tools on output quality, not features
Every AI tool demo looks impressive. The demo is designed to showcase the best case. Your evaluation should test the average case and the worst case. Run your actual data through the tool for two weeks. Measure accuracy, speed, and the time required to review and correct the output.
The evaluation framework: accuracy above ninety percent for automation, above seventy percent for augmentation. Speed should be faster than the manual process. Review time should be less than twenty percent of the time saved. If a tool fails any of these criteria, it is not ready for production. The AI tool market is moving fast. The tool that fails today might be the best option in six months. Re-evaluate quarterly.
Prompt engineering is a business skill now
You do not need to be a developer to get value from AI tools. You need to be able to write clear instructions. That is prompt engineering. The founders who learn to write effective prompts get ten times more value from AI tools than the ones who type one-line questions and accept whatever comes back.
The basics: be specific about what you want, provide context about your business, give examples of good output, and iterate. A good prompt is like a good brief for a contractor. It tells the AI what to do, why it matters, and what success looks like. Spend ten minutes learning prompt basics and you will save hours every week.
AI risk management starts with your data
The biggest AI risk for B2B companies is not sentient machines. It is data leakage. When your team pastes customer data, financial information, or proprietary code into a public AI tool, that data may be used for training. Your competitive advantage walks out the door one prompt at a time.
The policy you need today: no customer data in public AI tools, no proprietary code in public AI tools, and no financial data in public AI tools. Use enterprise versions with data processing agreements for anything sensitive. This is not paranoia. It is basic data hygiene. The companies that learn this lesson early avoid the breach that teaches it the hard way.
Automate with AI where the stakes are low
The first AI automations should be in areas where mistakes are cheap. Internal reports, first-draft emails, meeting summaries, and data formatting are low-stakes. Customer-facing communications, financial calculations, and legal documents are high-stakes. Start with low-stakes and expand as you build confidence in the tools.
The expansion path: automate internal processes first, then internal-facing customer processes, then customer-facing processes with human review, and finally customer-facing processes autonomously. Most companies should stop at step three. Fully autonomous customer-facing AI is still too risky for most B2B applications. The human review step is not a limitation. It is the feature that makes AI usable.
AI for sales is about preparation, not automation
The AI tools that actually help sales teams are the ones that prepare reps for conversations, not the ones that automate the conversations. Prospect research, call preparation, competitive intelligence, and follow-up drafting are where AI adds value today. Autonomous outreach and AI-generated proposals are where it destroys value.
The workflow that works: use AI to research the prospect before the call, generate a call preparation brief with relevant talking points, draft the follow-up email after the call, and update the CRM with call notes. The rep still has the conversation. The rep still builds the relationship. AI handles the preparation and the paperwork. That is the right division of labor.
Frequently asked questions
What should I ask an AI vendor before buying?
Where does my data go, is it used for training, and will you sign a data processing agreement? Then model performance on my data, and how pricing scales with my usage. In that order.
How do I know if an AI vendor trains on my data?
Read the terms, do not ask the rep. Look for a no-training commitment and a data processing agreement in writing. If the documentation is vague, assume your data is fair game.
What pricing model traps do AI vendors set?
Per-seat pricing that punishes adoption and usage pricing that punishes success. Model your cost at three times current usage before signing. If the economics break at scale, negotiate caps now.
Should I run a proof of concept with an AI vendor?
Always, on your data, with the team that will use it daily. Two weeks, predefined success criteria. A proof of concept that the vendor runs for you is a demo with extra steps.
What is my exit plan if an AI vendor disappears?
Ask before signing: can I export my data and prompts, and what runs without them? AI startups fold and get acquired constantly. If the honest answer is nothing portable, price that risk into the decision.
