The Ilu Toolbox, created by Deetken Impact and ProMujer, in collaboration with USAID, is a comprehensive resource developed by the Ilu Women’s Empowerment Fund to help companies address gender gaps and foster inclusive, equal business environments. It is structured around four "gender lenses" that provide practical strategies for organizational transformation: women in leadership, workplace equality, products and services benefiting women and girls, and equality in the value chain and advocacy. This toolbox is a valuable resource for investors conducting gender lens due diligence on potential investees, including financial service providers (FSPs). Investors can use the toolbox to evaluate current gender equality practices, identify areas for improvement, and assess the potential impact of gender-focused strategies on a company's competitiveness and societal contribution. For FSP-focused investors, the toolkit offers insights into how these institutions address gender equality in their operations and services. By leveraging this resource, investors can make informed decisions aligned with their gender lens strategies, while encouraging positive change in supported companies, and ultimately contributing to a more inclusive financial ecosystem.
