In response to a D&AD brief, I created a guerrilla marketing concept for giffgaff to extend their “Are you on giffgaff or something?” campaign, which celebrates the unbridled optimism in unconventional ways. Targeting 18–25 year olds, my solution needed to resonate with their priorities: value, sustainablity, and community. The result was giffgaffGO - an app feature that guides users to nearby murals, museums, green spaces, and local food and drink spots. By checking into these Giffstops, members earn rewards such as bonus data, refurbished phone discounts, and vouchers. The concept encourages young people to look up from their phones, explore their surroundings, and share optimistic moments, while reflecting giffgaff’s playful, sustainable, and up-to-good ethos.
