Overview

A fine jewellery brand with strong category momentum and a lifecycle stack that hadn't kept pace. We came in to audit the post-purchase system, tighten the acquisition engine, and run the kind of weekly cadence that turns big trading moments into repeatable ones. Five quarters in, sale windows are delivering consistent year-on-year growth, the lifecycle programme is doing real work between purchases, and creative is feeding the funnel with the kind of velocity the category rarely sees.

THE CHALLENGE

Fine jewellery is a category where every conversion has to be earned. The price point sits high enough that customers research, hesitate, and return. That means acquisition can't be measured on first-click economics alone, and the lifecycle layer has to do real work between purchase and re-purchase.

Coming in, the brand had momentum but a stack that wasn't fully translating it. The lifecycle programme had grown faster than its underlying logic, with overlapping segments and flows that no longer matched how the customer actually behaved. Acquisition was working, but the creative engine and the post-purchase system weren't yet pulling in the same direction, so peak moments were leaving revenue on the table.

The brief was hands-on from day one: audit what's there, rebuild what's broken, and turn weekend trade and sale extensions into repeatable events rather than one-off wins.

THE APPROACH

How the engagement was structured.

The work started with the lifecycle stack. A full audit of the post-purchase system surfaced the gaps: segments collapsed into one another, flows fired at the wrong moments, and the measurement layer underneath wasn't trustworthy enough to act on. We rebuilt it from the ground up, with cleaner segmentation, stricter naming conventions, and a weekly cadence that kept the rebuild moving rather than letting it stall in audit purgatory.

Acquisition ran in parallel. Paid social was restructured around creative velocity: a steady tempo of new concepts, ruthless retirement of fatigued assets, and naming discipline tight enough that the team could actually read the data they were producing. Creative strategy stopped chasing one-off heroes and started building on what worked between drops, so each new launch inherited everything the last one taught us about hook, format, and the customer the brand wanted to attract next.

Underneath all of it sat a weekly WIP rhythm. Acquisition, lifecycle and creative didn't run as separate workstreams reporting in: they ran as one team, with the founder's team inside the loop. Sale windows became coordinated moments rather than channel-level pushes, and the post-purchase system carried the customer forward instead of letting them go quiet.

THE OUTCOME

Weekend trading has strengthened steadily inside the partnership, with sale windows now delivering consistent year-on-year growth. Sale extensions have become genuine trading events, with the lifecycle stack carrying customers from the moment of acquisition through to repeat purchase without the leaks the original setup carried.

Acquisition runs with the kind of creative discipline the category needs: concepts tested, retired and replaced on a tempo the brand can actually feel in its numbers. The post-purchase system now compounds rather than churns, and the weekly WIP rhythm keeps the whole team moving as one, not three.

The partnership has held across five quarters and keeps paying off, with measurement, creative and lifecycle now working as one for a category that punishes anything less.
