Our Story
Founded in the early 2000s, Keystone Accountability emerged from a need for stronger measurement and performance management in organizations dedicated to social value. Initiated by David Bonbright, discussions on innovative measuring practices led to the establishment of Keystone in 2004, with support from the Omidyar Network and Hewlett Foundation. Over the years, Keystone has developed its Constituent Voice methodology, collaborating with clients like the World Bank and Gates Foundation to enhance accountability in the nonprofit sector.
