20 numbers for the result, 25 case write-ups for the process — from global giants to 200-person mid-caps, from China to the Middle East. Organized by industry, sources graded below.
The struggle: customers went from 40,000 to 316,000 in two years — the old playbook meant growing the support team 7× too.
What the AI did: holds the front line; routine questions resolved outright, complex ones escalated to a human, missed answers fed back into the knowledge base.
The struggle: the hotline caught only half of inbound calls; peak-hour queues, member complaints, and hiring costs that didn't add up.
What the AI did: voice AI answers every call first, handles routine business end to end, routes complex matters to a human agent.
