The OTT Conference is an invitation-only event as we have limited space. We are inviting think tank leaders and funders to register your interest.
Partnership and sponsorship
We are delighted to partner with the South African Institute of International Affairs (SAIIA) and to collaborate with the Institue for Security Studies (ISS), the New South Institute (NSI), Southern Hemisphere, and the AUDA-NEPAD Africa Policy Bridge Tank for the 2025 conference.
Each year we are grateful to our sponsors and funders who help us to deliver a truly diverse and impactful event. Get in touch if you would like to sponsor OTT Conference 2025.
What to expect
OTT conferences are designed to create opportunities for formal and informal interactions, and for participants to create sessions on topics relevant to them.
The programme includes a public event on the first evening, followed by a lineup of keynote addresses, plenary and parallel sessions.
The programme includes extended coffee and lunch breaks for networking, a marketplace of ideas, and fringe events hosted by participating organisations throughout the week.
We invite you to use your time in Johannesburg to organise meetings and fringe events with other conference-goers. If you want our support to connect you with other participants from a specific sector or region, reach out.
If you’re still unsure about what to expect, watch the sessions from the 2023 conference and 2024.
