The Participatory Budgeting Exchange, held in Barcelona, Spain in November 2018, brought together international participatory budgeting (PB) experts, implementers, and funders to co-design new approaches to better exchange ideas, solve common problems, and strengthen the results participatory budgeting delivers. Outputs from this event will continue to help shape how the Hewlett Foundation and other interested funders allocate and coordinate new resources to support global PB initiatives in 2019 and beyond.

The PB Exchange built upon months of participatory activities in 2018:




The William and Flora Hewlett Foundation is a nonpartisan, private charitable foundation that advances ideas and supports institutions to promote a better world.

The Hewlett Foundation is supporting the PB Exchange co-design process to inform its 2019 grant-making priorities and strengthen the impact of PB around the world.


Reboot is a research and design firm that works with change agents in government, civil society and philanthropy to solve civic challenges.

Reboot is facilitating the PB Exchange co-design process, and has recently conducted research on PB implementations in Madagascar, Mexico, South Korea, and Spain.
