Key Takeaways

  • Gartner found customers are about three times more likely to use third-party GenAI tools than company-provided chatbots to resolve service issues, and company chatbot use has not moved since 2022.
  • In B2B settings, 74% of customers who use GenAI have used it to complete a task on their behalf, compared with 58% of GenAI users overall.
  • Fewer than one in three consumers now give feedback to companies, an all-time low in Qualtrics XM Institute research, while 34% cut spending after a bad experience.
  • 74% of technology buyers in the TrustRadius 2026 study consulted customer reviews, and vendor marketing collateral ranked last among the resources they used.

Every renewal forecast rests on an assumption that rarely gets stated: when customers are unhappy, someone at the company will hear about it. A ticket gets logged, a chatbot conversation goes sideways, a survey score dips, and the account team gets a few months of warning. New research from Gartner, Qualtrics and TrustRadius suggests that assumption is breaking. Customers and buyers are still asking questions and still forming judgments, but more of that activity now happens in places the vendor does not own and cannot see.

The Service Conversation Has Left the Building

A Gartner survey of 3,566 B2B and B2C customers, fielded in February and March 2026, found customers are about three times more likely to use third-party GenAI tools than company-provided chatbots when resolving a service issue. Use of those outside tools in service interactions nearly doubled over the past year. Use of company chatbots has been statistically unchanged since 2022.

"GenAI is shifting some service interactions outside of company-owned channels," said Eric Keller, Senior Director Analyst in Gartner's Customer Service & Support practice. The behavior is more pronounced among business customers: 58% of customers who use GenAI have used it to complete a task on their behalf, and in B2B settings that figure rises to 74%.

The spending has not followed the customer. Service and support leaders invested a median 12% of their 2025 budget in AI, the highest share of the 10 business functions Gartner assessed, yet only 24% reported positive financial returns across their AI use cases. Much of that investment went into the very chatbots customers are now routing around. For a revenue leader, the cost line is the smaller problem. Every question a customer takes to an outside assistant is a support interaction that never creates a ticket, never flags a frustrated user, and never reaches the account team that owns the renewal.

Feedback Is at an All-Time Low

The second early-warning system is quieter still. Qualtrics XM Institute research based on a Q3 2025 survey of 20,001 consumers across 14 countries found that fewer than one in three consumers now give feedback to companies, the lowest share the institute has recorded. Yet 34% reduce their spending after a negative experience and 13% stop spending with the company entirely. Qualtrics estimates that poor experiences put nearly $3 trillion in global sales at risk in 2026.

The same research found that nearly one in five consumers who used AI for customer support saw no benefit, a failure rate almost four times higher than other AI use cases. The data is consumer, not B2B, but the mechanism carries over: customers who are not heard do not complain louder, they spend less and leave. Isabelle Zdatny, Head of Thought Leadership at Qualtrics XM Institute, put it plainly: "Companies cannot afford to treat customer experience as a separate initiative."

There is a bright spot, and it points at what matters. Forrester's 2026 US CX Index recorded the first year-over-year rise in customer experience quality since 2021, with 26% of the 225 brands tracked in both years improving significantly and 7% declining. The largest gain came in emotion, which Forrester analyst Pete Jacques describes as often the strongest predictor of loyalty, advocacy and retention. Emotion is also the dimension a closed ticket or a deflected chat captures least well.

Buyers Are Listening to Each Other, Not to You

The same pattern runs through the front of the funnel. The TrustRadius 2026 B2B Buying Disconnect Report, summarized in an HG Insights analysis, surveyed 1,862 technology buyers and 444 vendors. It found 74% of buyers consulted customer reviews and 53% spoke with a peer, while review-site use rose from 58% in 2025 to 63% in 2026. Vendor marketing collateral ranked last among the resources buyers consult. And 47% of buyers said they trust online resources less than they did a year ago, up from 39%.

Put the two halves together and the picture is consistent. Prospects form their view of a vendor from reviews, peers and AI assistants. Customers resolve their problems with AI assistants and voice their frustration, if at all, on review sites and in peer conversations. In both cases the most honest signal about the account is being generated somewhere the CRM never looks.

That changes what a healthy account looks like on paper. A customer with no open tickets, no chatbot escalations and no detractor score used to be a safe renewal. Increasingly, it may simply be a customer who stopped talking to you. Silence, on its own, is no longer evidence of satisfaction.

The CRO Playbook for a Quieter Customer

Customers have not stopped forming opinions about the companies they buy from. They have stopped telling those companies first. Revenue teams that want an early warning will have to go and get it, because it is no longer going to arrive on its own.
