Case Study: Grover scales subscription promotions and referrals with Voucherify

How Voucherify empowers Grover's marketing team

Grover, a German subscription rental service for tech products like smartphones, laptops, and cameras, needed a more flexible promotion system than its built-in coupon tool could provide. The company struggled to support recurring payments, targeted customer segments, and redemption limits, so it turned to Voucherify to power promotions for its custom e-commerce stack.

With Voucherify’s APIs and Node.js SDK, Grover launched subscription discounts, student offers, influencer codes, and a double-sided referral program with custom metadata-based targeting and fraud controls. Voucherify helped Grover integrate in about a week, and the company has since launched 750+ promo campaigns, sends 40,000+ API requests daily, and manages 200+ customer metadata properties.
