Case Study: Dollar Shave Club achieves +84% YoY retention and 13% sales lift with Partnerize

Razor-sharp acquisition and retention, powered by Partnerize

Dollar Shave Club, a razor subscription service with millions of members, needed to drive higher customer lifetime value by improving retention from the affiliate channel on the Partnerize platform. Working with agency The Specialist Works, the brand wanted to understand when affiliate-acquired customers became profitable (a 50% 12‑month retention threshold) and identify optimal commission rates to boost long-term value.

The Specialist Works used Partnerize’s integrated solutions — including Discover, dynamic commissioning and reporting/analytics — to build a measurement framework, recruit best-fit partners, and reward partners once customers reached targeted subscription points. By using Partnerize to prove incrementality and optimize commissioning, the program achieved an 84% YoY increase in retention, a 13% YoY sales uplift, stronger customer insights, and affiliate cohorts that out-retained other paid channels.
