The most dangerous number in customer experience isn’t low—it’s shiny. In this CX Pulse Check, we unpack why a single score can seduce teams into storytelling that investors love and customers don’t feel, and we make a case for the harder, more honest work of proving value creation by cohort, not by kudos. With Rob Markey of Bain & Company and Harvard Business School, we discuss whether customer metrics predict growth or distract from it, and we separate real loyalty from repeat purchase.
We go straight at the NPS debate: what the score can predict, where it fails, and how it becomes powerful only as part of a system that links feedback to actions that change renewal, cross-sell, referrals, and cost-to-serve. We talk airlines, captive markets, and the language games behind “loyalty” programs that purchase repetition without building emotional commitment. Then we get practical. You’ll hear a little about how to read interaction telemetry for risk signals, and build models that translate service performance—wait times, abandon rates, repeat contacts—into forward revenue forecasts your CFO will respect.
This is a great listen for leaders who want both heart and proof: real-time feedback to understand emotion and expectation shifts, behavioral data to see what customers actually do, and investor-ready visuals like tenure curves and revenue per customer by acquisition year. If you’ve ever wondered how to tell a CX story that earns budget because it earns returns, tune in to this conversation.
