In the world of tech accessories, the phone case is often viewed as a peripheral product–a commoditized accessory piggybacking on the innovation of mobile devices. Far from the complex electronics and sophisticated software inside phones, cases are seen as plastic shells or rubber bumpers with limited value-add. How did CASETiFY, a Hong Kong-based phone case startup, become a global sensation in this unexpected product category? This paper showcases CASETiFY by spotlighting the major factors that led the brand to success. We do so by deep-diving into CASETiFY’s various projects and initiatives and identifying three crucial phases in its history–the Value Creation phase, Value Communication phase, and Value Delivery phase. We highlight how, in each of these phases, CASETiFY leveraged on both the social aspects (e.g., brand communities, authentic brand messaging, providing a sense of belonging) and the individual aspects (e.g., self-expression, individualism) of its target consumers’ psyche to cultivate success factors such as intentional creativity, intensive branding, and the identification of consumers’ psychological needs. While extensive case studies exist on prominent tech companies, academic resources on peripheral accessories, a niche side of the tech industry, are limited. By documenting CASETiFY's fascinating journey, this case study sparks a scholarly discussion on an unconventional Asian success story. It also serves as a structured reference for commoditized-accessory businesses to learn about deriving success through challenging industry norms, recognizing overlooked opportunities and thoroughly understanding one’s target consumers.
