Gavin Hayman

Executive Director

Gavin is honored to be the Executive Director of Open Contracting Partnership, a silo-busting collaboration across government, business and civil society to open up and transform public contracting and procurement. Gavin plans to reinvent one of the largest markets in the world – covering 1 in every 3 dollars spent by government – as a smart, user-centered digital service, improving trust, inclusion and sustainability.

Before joining the Open Contracting Partnership, Gavin was Director of Campaigns and then Executive Director of Global Witness. He oversaw the organization’s groundbreaking and award-winning investigative, campaigning and advocacy work uncovering secret deals, corruption and conflict around the world. He helped create the international Publish What You Pay campaign and negotiated the intergovernmental Extractive Industries Transparency Initiative to improve disclosure and oversight of over trillion dollars of oil and mining money paid around the world.

He is also an expert on illicit financial flows and helped lead global efforts to end the abuse of anonymous shell companies for money laundering and financial crime, including at the G8 and Open Government Partnership.

He has a Doctorate from the University of Reading and has worked with Chatham House in London and the United National Environmental Programme in the past on analyzing and investigating global environmental crime.

Kathrin Frauscher

Deputy Executive Director

Kathrin is the Deputy Executive Director and Gavin’s co-pilot in leading the Open Contracting Partnership. Kathrin’s journey as a social entrepreneur started in an unlikely place – the World Bank Institute, the incubation lab of the World Bank. Kathrin worked in countries such as Nigeria, Uganda, and Mongolia on challenging but potentially transformative sectors including mining, construction, and service delivery. Once she realized the potentially massive impact that more accountable procurement processes could have, there was no turning back. While still at the World Bank, Kathrin and her team there began a user-centered iterative process to create a global organization that was better equipped than the World Bank to work across stakeholder groups in developed and developing countries to open up government contracting. Kathrin now co-manages the Partnership with Gavin where she is still thrilled by the daily opportunity to change how contracting can deliver value for everyone. Before working at the World Bank for ten years, she got a Masters in Advanced International Relations from the Paul H. Nitze School of Advanced International Studies of Johns Hopkins University and a BA in Economics from the University of Vienna.
