A business I worked with had a familiar problem: high cost per acquisition, and a journey that leaked people right after they'd converted.
Two different teams, two different scorecards - one on getting people in, one on keeping them once they'd arrived. Neither team was doing anything wrong. Nobody owned the join between the two.
Redesigning the acquisition journey and the onboarding experience together, as one continuous thing rather than two handoffs, delivered 40% growth in acquisition and a 50% reduction in cost per acquisition in the same programme.
Neither number moved because of a bigger budget. They moved because the join stopped leaking.
Where does your customer's experience quietly cross a boundary between two internal teams?
