Who We Are

Evidence to Impact Advisory is an independent consultancy led by Dennis Bours, with over two decades of experience across multilateral development banks, global funds, foundations, and international organizations. The firm operates as a networked advisory platform, drawing on a global community of experts to respond to complex, multi-dimensional challenges.
