This brief by Kore Global synthesises recent evaluation findings to provide the first cross-development finance institution (DFI) evidence on whether and how gender lens investments deliver meaningful outcomes for women. Drawing on four independent portfolio evaluations conducted between 2023 and 2025 for British International Investment (BII), Proparco, FinDev Canada, and FMO, the Dutch entrepreneurial development bank, the brief consolidates findings on 81 unique investments. It offers a clear view of how DFIs are applying the 2X Criteria across diverse geographies and sectors, and what this means in practice for women as employees, leaders, consumers, and entrepreneurs.
