Change rarely happens in isolation. Behind every breakthrough, every movement, every new possibility lies a catalyst: a spark that sets everything in motion. But the spark is only the beginning. Transformation happens when that energy is directed and shaped into something lasting. A solution. A system. A new way in. At TEDxSugar Hill 2026, we explore the catalysts that shape our world. Not just as a moment of ignition, but as the start of something intentionally constructed. From one bold idea to a movement that opens doors for others, this event celebrates those who don’t just spark change — they build it.
