At the heart of our work is a shared perspective that the leaders of social innovations should lead the charge of evidence building to improve practice. Their questions, well answered, will inform policy and scale knowledge and learning in line with business and operating realities. Funders, data and technology firms and researchers play vitally important roles in fueling and supporting efforts to improve, build evidence, and scale. Evident is pleased to work with these stakeholders through an innovative shared services approach. We base our efforts in a set of principles for the proof of concept phase, and larger culture of how Project Evident works with organizations, collaborators, and the field.
