Governing Board

Our Governing Board oversees the Open Contracting Partnership since becoming an independent 501(c)(3) charity and replaces the Advisory Board in place between 2014 and 2021. The Governing Board is a multi-stakeholder board made up of renowned individuals from across government, the private sector, civil society, the technology sector and development organizations. It meets twice a year and on a regular basis in its subcommittees. All governing board members serve in a personal capacity and follow OCP’s robust Code of Ethics and conflict of interest policy.

We are grateful to our Advisory Board that led us through the first years of Open Contracting Partnership, including our outgoing Advisory Board Maria Margarita “Paca” Zuleta, Claire Schouten, Jeni Tennison, Andrew Clarke, Rudi Borrmann, and Seember Nyager.

Opaque contracting leads to waste, inefficiency and corruption – none of which helps deliver goods, services and infrastructure to people in need. That’s why open contracting is so vital. Its focus on disclosure and participation helps ensure improved development outcomes for governments, citizens and companies.
