PurposeCognitive drivers of opportunity identification and development are important in entrepreneurship. This study examines antecedents of opportunity development among women founders of digital platform start-ups, defined as technology-mediated sites that facilitate user interactions, processing of transactions or other innovative practices. The opportunity identification and development literature framed our exploration of drivers into digital entrepreneurship among women in a middle-income economy, an area under-represented in prior research.Design/methodology/approachThis research uses in-depth interview data with women founders of five digital platform start-ups in South Africa. The authors supplemented primary interviews with secondary data from a global big data site to provide context for how investors are funding women-owned start-ups in the country.FindingsEntrepreneurs’ heightened alertness to opportunity developed from a confluence of factors such as personal values, impatience at the slow pace of change in post-Apartheid South Africa, corporate ennui and building for-profit business models driven by social purpose. Respondents had multiple identities, including gender, culture and generation that influenced their development as entrepreneurs and their adoption of digital platform strategy for start-up ventures.Research limitations/implications Multiple factors influence women entrepreneurs during the opportunity identification and development process as they enact the creation of digital platform start-ups. The authors recommend additional research linking opportunity identification and development to gender in emerging markets.Practical implicationsSouth Africa is witnessing the emergence of women-owned digital platform start-ups that attract risk capital investment. These entrepreneurs are university educated and use prior corporate experience to create growth-oriented companies that government should support.Originality/valueThe study contributes to opportunity identification theory building based on context, specifically how the concepts and strategies can inform new models that include women entrepreneurs.
