Sardio builds customer engagement and retention strategies that increase lifetime value and reduce churn. Acquisition gets the credit but retention drives the margin. For most ambitious brands, a 10% improvement in retention has a larger impact on profitability than a 20% increase in new customer acquisition. We build the systems that make retention scalable.

• Customer lifecycle mapping - defining the key moments in the post-purchase journey where the right message drives the most value
• Klaviyo email and SMS automation - welcome sequences, post-purchase flows, winback campaigns and loyalty programmes
• Segmentation and personalisation strategy - moving from batch-and-blast to behaviour-triggered, individually relevant communications
• Loyalty programme design and implementation - building structured reward systems that increase purchase frequency and brand affinity
• Customer lifetime value optimisation - identifying the segments worth investing in and the levers that increase their value
• Churn prediction and prevention - identifying at-risk customers before they lapse and deploying the right intervention
• Voice of customer and NPS programmes - systematic feedback collection that informs product, service and marketing decisions

The most profitable customer you can acquire is one you already have. We help you build the system that keeps them.
