Why AI Alone Isn't Enough: The Real Key to Customer Service Success

As companies move from AI pilots to full-scale deployment, customer service has become the proving ground for enterprise transformation. John Kelleher, VP for UKI and MEA at Zendesk, argues that 'better AI' no longer wins — it's the change management around it that drives real outcomes.

The Shift from Back-Office to Front-Office

Customer service has evolved from a cost center to a mission-critical function that drives brand engagement and growth. Companies that have run AI pilots are now confident enough to scale, with most choosing to apply AI to customer or employee service first.

The Change Management Challenge

Business leaders are now requesting help with change management, not just technology. The goal is to maximize ROI on AI investments while ensuring security and speed. It's an iterative process in a volatile world.

AI Fatigue and the Real Differentiator

There's real fatigue around AI messaging — everyone claims to have the best AI. But until AI is embedded into genuine business transformation programs, promises won't be fulfilled. The key is wrapping the right change management around the technology.

Success Stories: South Africa Leading the Way

Companies in South Africa are driving AI-first transformation at a remarkable pace, partly due to infrastructure gaps that create a thirst for faster AI adoption. Messaging channels like WhatsApp dominate, making customer service automation a perfect fit.

Hollywoodbets, a South African gaming company, is a standout example. They've scaled AI agents rapidly, outpacing larger competitors by embracing a strong partnership with Zendesk from the CEO down.

The Human Touch: Using AI Internally

Kelleher shares a personal experience using Zendesk's AI-powered employee service to inquire about logo usage for his son's school rugby tour. The process was seamless — a conversation with an AI agent, followed by links and case resolution without human intervention. Using the product internally adds credibility when talking to customers.

HyperArc: Democratizing Insights

The most exciting announcement at Zendesk Relate 2026 is HyperArc, which allows users to interrogate knowledge databases using natural-language prompts. It democratizes insight across the workforce, making analytics accessible to everyone, not just report builders. This is significant because insight is the hard part — automation can drive efficiency, but analytics reveal what's actually working.
