The Society of Independent Show Organisers (SISO) is a global trade association representing for-profit event organisers across exhibitions, conferences, and live events. Founded to support independent organisers, SISO provides a trusted environment for leaders to connect, share experiences, and learn from one another.

With a membership spanning more than 195 organisations worldwide, SISO brings together a diverse community of event professionals who collectively deliver thousands of events each year. Through peer-to-peer networking, education, and industry insight, it helps members navigate challenges, improve performance, and stay ahead in a rapidly evolving market.

At its core, SISO is built on open collaboration. By creating a non-competitive space for honest conversation and knowledge sharing, it enables organisers to exchange ideas, develop best practice, and drive growth across the global events industry.
