The OTT Conference 2025 is set to be a monumental gathering for think tank leaders, funders, and policy experts from around the globe, hosted in Johannesburg, South Africa, in partnership with the South African Institute of International Affairs (SAIIA). As the premier global forum for think tanks, this conference aims to foster discourse across a variety of disciplines, sectors, and ideological perspectives. The conference is designed to create both formal and informal opportunities for participants to engage in discussions that are relevant to their interests, with sessions that can be tailored to specific topics. The program features a public event on the opening evening, followed by keynote addresses, plenary sessions, and parallel discussions, all thoughtfully scheduled to include ample networking opportunities during extended coffee and lunch breaks. Additionally, fringe events will be hosted by participating organizations throughout the week, encouraging attendees to maximize their time in Johannesburg by organizing meetings and connecting with others in the field.
