The SEEP Network’s 2014 Annual Conference will serve as a platform to promote learning and exchange around proven and emerging approaches, strategies and models for reaching substantial numbers of poor and vulnerable populations on a sustainable basis. The conference will explore scalable solutions that involve inclusive business models, private sector partnerships, technology applications, and new investment and financing models. The conference will organize learning around overarching questions such as: How do we define scale? What are the greatest challenges to scaling development impact? Which innovations in products, delivery and partnerships promise the greatest results and are likely to endure? How can market facilitators be more effective in this context? What are the potential trade-offs between reaching large numbers and achieving impact?
