Summer Weisberg of Testlio on Building Customer Trust in AI

Testlio CEO Summer Weisberg on why an AI feature can pass every automated check and still fail the customer - and why companies must govern AI at the point of use, with human judgment where it matters.

Where do you most often see a gap between a company's brand promise and its everyday customer operations, and what does that gap look like for the customer?

The gap shows up most often in the everyday moments a company assumes are fine because nothing is technically broken. A button works but feels wrong. A recommendation engine technically returns results, but nothing that is right for the customer. An AI-generated feature passes every automated check and still confuses or disappoints real users.

Take a music recommendation platform that keeps returning to a genre you don't like. Did it fail? No. Are you satisfied? Also no.

Failures like these erode trust slowly, and by the time a company notices, they're already showing up in churn or support tickets. What leaders underestimate is how little patience that buys them. Customers have choices. You cannot build loyalty on an experience customers merely tolerate, and every clunky interaction gives them one more reason to try an alternative. The minute a better option is available, they’re likely to leave.

A lot of leaders treat quality as a binary pass/fail question: does it work, or is it broken? If that's your only lens, you're missing the bigger picture. True quality is about whether the experience is intuitive, accessible, and beautiful. Because of that way of thinking, many companies rely on automation for things that are better tested by real humans. Automation is great for speed, but it's blind to nuance. It can't tell you if a workflow feels clunky or if a design choice is alienating users. It should be part of your QA strategy. Where and how you use it is what sets companies that can build and sustain decades of customer loyalty apart from those that can't.

Can you share a specific example of a process, policy or system change that strengthened customer trust in a brand? What changed, and how did you measure the result?

BitPay's customer-reported issues dropped 15% after they partnered with Testlio, and their customer satisfaction scores stabilized. Here's what that looked like.

BitPay is one of the longest-operating crypto payment companies, with customers in more than 200 countries. They didn't have an internal QA team, so testing fell to development and product teams that were already stretched thin. Coverage was inconsistent, and their core team is based in the US while their users are everywhere.

Crypto raises the stakes because blockchain transactions can't be rolled back the way a card payment can. A mistake at checkout means lost money and a customer who doesn't come back. So we split the work by what each side does best. Automated scripts handled the broad, repeatable coverage. Real testers in real regions handled the moments where a failure can't be undone, like wallet connections, transaction signing, and payment confirmation, on real devices and under real local conditions. That combination is what moved the number, and it's the same model I'd point any brand to when its promise depends on getting a critical moment right every time.

How should businesses decide which rules and approval requirements protect customers and which create unnecessary effort or prevent employees from resolving problems?

The consequence of failure should determine the level of oversight. That's the simplest way to sort rules that protect customers from rules that just slow people down. For any rule or approval step, ask what it protects, what the risk is if that moment goes wrong, and what the fallout would be. A rule that guards a high-stakes moment like login, checkout, or account access earns its friction. A rule that adds a sign-off to low-risk, reversible work is just effort, and it's usually why an employee can't fix a customer's problem on the spot. The number of customers affected isn't the deciding factor either. An issue affecting customers in one region can look small next to millions of users, but if it puts customer data or your reputation at risk, it deserves the strict rule.

As businesses add more AI features, their responsibility and liability go up, not down. AI is powerful, but it needs guardrails, and that's what even the frontier labs are now advocating for. The catch is that governance at the model layer isn't the same as governance at the point of use. Even if frontier labs get their house in order, they're optimizing for their own risk and liability. They won't define what safe means for your data sensitivity, regulatory exposure, or customer expectations. Waiting for AI labs, governments, or regulators to map out your governance sets you up for failure, and grabbing a generic framework off the web won't cut it either. Your validation strategy and oversight need to align directly with how your specific business and brand operate.

When your AI fails, you can't shift the blame to vendors. Customers hold your brand accountable. In an Acquire BPO survey of 600 U.S. consumers, 70% said they'd consider switching brands after just one frustrating AI support experience.

A single hallucination, off-brand reply, or safety failure can wipe out trust that took years to build and automated tools routinely miss these issues. That's precisely where human judgment comes in. During our early-adopter chatbot testing, nearly half of high-severity issues stemmed from models struggling with safe refusals, escalations, and fallback handling. Our approach covers output accuracy and intent resolution, misinformation, PII and data privacy, safety guardrails, bias, and localization. An AI agent that runs smoothly in a sandbox can still fail when exposed to real devices, regional payment systems, or users who don't stick to the script.

It helps to treat an AI model like a new employee or intern: hand them a rulebook, train them on the job, supervise their work until they prove reliable, and keep auditing them. AI can memorize an entire handbook and still miss nuance. A human, on the other hand, immediately spots when a technically accurate response will sound biased, tone-deaf, or unfair to a customer.

Where can AI and automation improve a company's ability to deliver its brand promise, and what evidence should leaders require before calling the change successful?

I'm not an AI skeptic. AI helps customers find answers on their own, complete tasks without waiting on a person, and get up to speed on a product faster. It's doing the same for internal workflows. But whether your AI faces customers or runs behind the scenes, the same rule applies. It still has to be validated with real people.

We use AI to orchestrate crowdsourced testing so results get into clients' hands faster, and our experts can focus on the human insight machines can't replicate. That's proof we see the value. AI makes things faster, and it lets you apply human judgment more efficiently. It doesn't replace it.

Before anyone gets to metrics, a leader should be asking a harder set of questions. Is this a job that's even meant for AI? What happens when it goes wrong? Does it know when to escalate to a human? How often will we review it? If you can't answer those, you don't have a deployment yet. You have an experiment running on your customers. As we start seeing AI features make their way into customer workflows, we need more humans to push on the feature and try to break it the way your actual users would.

Now moving on to what makes a change successful. You need clear metrics defined up front, meaning the specific outcomes they are improving, whether that's faster resolution, fewer escalations, or a shorter path to a customer's first success. AI outputs should be reviewed against business objectives and quality standards. And the test that matters is relevance. Is the experience right for the customer, or did the feature just return something? Most importantly, you need to ensure your metrics prove that your AI behaves responsibly in the hands of users because that’s what regulators want to see, not whether your AI “functionally” works.

I’ll close by saying leaders need to know AI systems are built on trust, and trust can't be engineered. It has to be validated with real people, in real environments, and with real edge cases. Internal teams have blind spots, so external evaluators and diverse human reviewers are the only reliable way to see how AI behaves in the hands of real users. Because AI gives brands extraordinary speed and scale, but human judgment makes sure that what they deliver is actually worthy of the brand promise.
