Steward Leadership Summit 2025

As SAC's annual flagship event, the summit is a high-profile invite-only event bringing together global leaders from the public and private sectors.
The theme of this year's summit is Happiness and Compassion for Prosperity.
In today's volatile landscape - shaped by heightened economic uncertainty, climate change, and rising inequality - organisations must rethink what it means to thrive.
The most effective and impactful leaders today embrace a win-win-win mindset, delivering benefits for business, society, and the environment. Happiness and emotional well-being empower these leaders to act with empathy, build resilience, make better decisions, and drive sustainable prosperity. In an interdependent world, they act with compassion to turn complexity into opportunity and foster long-term prosperity for all stakeholders.
This summit will feature thought-provoking dialogue and visionary keynotes, inspiring leaders to do well by doing good in a rapidly changing world.
