We Took Our AI Tool to Banks. Here Are the 3 Questions They Asked That Silicon Valley Never Does.
I've probably done 100 demos of AiKey over the past few months. Most go the same way: developers nod along, spot the use case in their own team, and start asking about pricing.
The demos with financial CTOs were different. They listened politely, then asked questions I'd never heard before. Not about features. About failure modes.
I kept a log after the third one. Here are the three questions that kept coming up, and what they taught us about the gap between "AI works for our team" and "AI works for our organization."
Question 1: "Where does the AI traffic go on your current network?"
The startup answer: "Through our API gateway, same as everything else."
The follow-up: "What happens when an AI batch job and a core transaction hit the same rate limiter?"
I had no answer. Neither did the CTO, but he was the one asking the question.
Here's what I learned: most companies route AI traffic through the same infrastructure as their core business traffic. Same gateway. Same load balancers. It works fine until it doesn't. An AI agent with aggressive retry logic can generate thousands of calls in minutes. If those calls share a gateway with payment processing or order fulfillment, the AI traffic wins the race for capacity — and the core business loses.
The banks solve this by having a dedicated AI gateway. Separate rate limits, separate capacity planning, separate priority queues. The AI can burst without starving the business.
We added this to our architecture after the third conversation. It's now a standard deployment option.
Question 2: "What runs before the model gets called?"
The startup answer: "Our prompt template handles the formatting."
The follow-up: "That's not what I'm asking. What compliance checks are running on every request, before it leaves your network?"
This was the question that made me realize how different the operating environment is.
In a regulated industry, every AI request needs to be inspected before it reaches the model provider. PII detection. Prompt injection shields. Model allowlist enforcement. Policy matching. All of it, in milliseconds, on every single call.
Most startups treat this as a "nice to have." The banks treat it as a hard requirement. They literally cannot use a tool without it.
The hard part isn't writing the rules. It's making the checks fast enough that developers don't notice them, and accurate enough that false positives don't become a daily frustration. We spent three months iterating on the runtime compliance layer after that conversation. It's still the feature I'm most nervous about shipping.
Question 3: "How do you split the bill across 12 departments?"
The startup answer: "One account, one monthly invoice."
The follow-up: "That's not a solution. That's the problem."
This one hurt because it's true. Most AI infrastructure treats costs as a single line item. But organizations have finance teams that need per-department, per-project, per-user attribution. Not at month-end. In real time.
One CTO told me they have five people spending half a day every month reconciling API costs across departments. Five people. That's a full-time equivalent, just to figure out who spent what on AI.
The fix isn't "better accounting." It's infrastructure that carries attribution metadata on every call. Project, team, user, model, purpose. Tagged at the proxy level, aggregated in the dashboard. The finance team gets what they need without asking developers to "remember to add the department tag."
What I'd Do Differently
If I were starting over, I'd lead with these three questions in every conversation — not just with banks, but with any team that has more than 20 people using AI.
The standard startup narrative — "AI is magic, here's how to integrate it" — skips the part where scaling introduces infrastructure problems that look nothing like the prototype phase.
The banks didn't teach us new features. They taught us failure modes. And those failure modes are coming for every team, eventually.
AiKey is a credential and governance layer for AI infrastructure. We support gateway isolation, runtime compliance checks, and organizational cost attribution.
If you're dealing with similar scaling challenges, I'd love to hear how your team is handling them.
