"We are pleased to share with the impact community our review of 150 impact investing platforms, networks and organizations that promote, support or convene investors in the impact finance area. Prompted by our own experience as investors, technologists, and system designers, we were interested in better understanding prevailing business models and motivations for sharing (or hoarding!) data, innovations, and investors. Our analysis builds on ongoing work to design and develop an interoperable, global, modular, distributed, and democratic infrastructure for mobilizing data, innovations, and capital at the volume and velocity required to achieve the Sustainable Development Goals. Our purpose, in addition to providing an overview of the platform landscape, is to identify opportunities for alignment of prospective partners, around the strategy, design and implementation for such global impact infrastructure; and explore scenarios for collective action."
