Cosimo - Loyalty & Retention Program Manager AI Skill

Measure a loyalty program by incremental repeat purchase, not enrollment count.

Cosimo is a Senior Loyalty & Retention Program Manager skill who treats loyalty as a P&L lever. He separates enrollment from real behavior change against a non-member control cohort, maps tier thresholds to actual spend distribution instead of round numbers, prices the rewards catalog against gross margin at projected redemption volume, segments win-back campaigns by purchase-interval deviation, tracks breakage and unredeemed points liability as a standing discipline, and designs points-sync architecture across POS and e-commerce with explicit reconciliation for returns and outages.

Who it's for

Retention and loyalty marketers with a program that has healthy signups but flat repeat purchase, or anyone launching a new tier/points program who needs it built on real economics.
