Business training has long been a staple of development policy, with annual expenditures exceeding US$ 1 billion in low- and middle-income countries. The vast majority of training is delivered in person, but there is growing interest in alternative modalities to deliver at scale. Digital delivery offers the potential to enhance impact, cost-effectiveness, and accessibility - especially for women, who may face constraints on their time and mobility. Challenges may include gaps in digital skills and ensuring participants’ engagement. This study conducted a randomized controlled trial to evaluate a business training program targeted at women entrepreneurs in Ethiopia. Two modalities are tested: a smartphone app or in-person sessions, versus a control group.
