Meanwhile, Hart and his colleague Erik Simanis at Cornell University's Center for Sustainable Global Enterprise advance another approach, one that focuses on the poor as business partners and innovators, rather than just as potential producers or consumers. Hart and Simanis have led the development of the Base of the Pyramid Protocol, an entrepreneurial process that guides companies in developing business partnerships with income-poor communities in order to "co-create businesses and markets that mutually benefit the companies and the communities". This process has been adopted by the SC Johnson Company[8] and the Solae Company (a subsidiary of DuPont).[9]
