Fridayslab

Fridays Lab is the operator of Retentics, a customer retention product for e-commerce brands running on Shopify and Klaviyo. Retentics analyzes a merchant's transaction history to identify purchase cycles, repeat-order patterns and buyer segments, then automatically generates corresponding flows inside Klaviyo and triggers them based on real-time customer behavior, positioning itself as a flow-optimization add-on rather than a replacement for the email platform.

The product is organized around three stages: learning how customers buy at both SKU and storewide level; auto-generating audience-specific flows in Klaviyo preconfigured with timing and logic; and triggering the appropriate message based on signals such as purchases, browsing and replenishment cycle position. Feature areas include send timing derived from consumption rate with per-variant logic across bundles, variant-level product recommendations with cross-sell and upsell logic, offer control including an escalating incentive as deadlines approach, winback incentives tied to lapse behavior and suppression of discounts for high-intent buyers, and AI-surfaced segments that update automatically alongside user-built dynamic filters. Documented buyer segments include frequent one-time buyers routed to a first-purchase bounce-back flow, lapsed customers routed to winback, and periodic bulk buyers routed to replenishment.

Earlier company communications described Retentics as a hyper-personalized recommendation solution integrated with Shopify, aimed at boosting repeat purchases for domestic and international e-commerce companies, with reported effects of 1.8x higher CRM message conversion and 4x higher customer lifetime value.
