Since 2004, WDI has been a leader in exploring enterprise-based solutions to the poverty experienced by the “base of the pyramid” (BoP) — the 4.5 billion people who live on less than $3,000 a year. In this effort, the Institute affiliated with several key thought leaders, including C.K. Prahalad, Stuart Hart and Ted London. During the years that followed, many organizations recognized the business opportunity in engaging with the BoP , and expressed an interest in developing and launching such enterprises. However, too few went on to achieve sustainable impact at scale. These results motivated the Institute to launch the Scaling Impact Initiative in 2016, which focuses not on whether business should serve the poor, but how to do it better. The initiative addresses this challenge by identifying the most relevant and impactful questions facing enterprises, analyzing past successes and failures, and developing practical and actionable recommendations. WDI has attracted collaborators that include multinationals such as Walmart, ITC Limited and CEMEX; entrepreneurial ventures such as Honey Care Africa and VisionSpring; and development organizations such as the Global Alliance for Clean Cookstoves, USAID, GIZ and CARE International. Leveraging a decade’s worth of knowledge gained in the BoP domain, the Scaling Impact team is developing cutting-edge strategies, frameworks and processes that provide a roadmap to scale for enterprise leaders and their partners.
