A mobile-first global brand, Springster digitally connects marginalised and vulnerable girls to online content designed to equip them with the knowledge, confidence and connections they need to navigate the complex choices of adolescence. With millions of girls in the global South now using mobile phones, Springster has been developed to meet girls where they are; at her level and type of phone use. Working with partners such as Vodafone and Facebook’s Free basics, we reach girls by delivering Springster’s content via the channels girls use everyday. Springster is available for free with no data charges (on Free Basics Mobile networks), while it is also accessible through private and public social media channels, to keep pace with girls’ ever evolving needs. Based around an inclusive culture of sharing real-life experiences, Springster provides a space for girls to engage with topics like puberty, education, money management and relationships. Springster’s content, co-created with girls, is designed to entertain, inspire and help girls to make positive choices that change their lives. Springster adopts a mixed quantitative and qualitative research methodology, including online comment analysis and control vs exposed trials (comparing those who have seen our content with those who haven’t) to measure the performance of our product and its impact on girls’ knowledge, attitude and behaviour change. By breaking down barriers and showcasing alternative pathways Springster enables girls to gain the knowledge and power they need to create positive change in their own lives, wherever they live.
