Getting kids excited for a supermarket trip isn't easy. PLUS Supermarket wanted to turn their weekly grocery run into something families actually looked forward to. The Brand Father built a custom web tool that let users design their own personalized Eredivisie sticker sheets, blending the nostalgia of physical sticker collecting with the thrill of digital personalization. No app download, no friction, just pure creative play that lived exactly where their audience already was. The campaign didn't just drive engagement, it drove revenue. Over 90,000 users designed their own sticker sheets, and we converted a massive share of them into paying customers with 40,000+ paid orders. Converting into a 44.4% conversion rate. The result: a digital solution that was playful and made a massive impact.
