Inclusive innovation is increasingly recognised as pivotal in addressing inequalities and achieving the United Nations’ Sustainable Development Goals. While existing literature predominantly emphasises vertical inequality and economically marginalised groups, in this study we examine how digital technologies promote inclusive innovation by addressing intersectional, horizontal inequalities. Drawing on both case studies and interview data from the UK and Germany, we explore how digital ventures incorporate technological and social dimensions to support marginalised groups. Using the lens of intersectionality, our findings highlight the nuanced roles of digital platforms, tools, and innovations in enabling societal participation for individuals experiencing multidimensional exclusion. Our study makes three key contributions. It extends the understanding of inclusive innovation by addressing intersectional horizontal inequalities, highlights the role of digital technologies in overcoming structural and cultural barriers to inclusivity, and further develops intersectionality theory by demonstrating how overlapping identities shape the adoption and use of digital solutions.
