This case study details how Gozney, a pizza oven manufacturer, has successfully utilized customer advocacy to drive significant business growth since implementing the Mention Me platform in 2021. Initially launching a referral program to acquire new customers, Gozney has expanded its strategy to leverage customer advocacy for increased revenue. The company runs referral campaigns in five global markets, continuously learning about customer preferences through experimentation and A/B testing of various campaign elements. The results indicate that Gozney's new Dome oven featured in referral journeys has led to a threefold increase in referrals. Additionally, referred customers demonstrate higher spending, with a 21% increase in their first six months compared to those acquired through other channels, and they introduce five times more new customers. Gozney plans to further enhance their marketing efficiency by integrating advocacy data into their CRM, aiming to maximize ROI and reduce customer acquisition costs across channels.
