The story behind Oz’n’gO name
Oz’n’gO stems from an observation: caught up in day-to-day business and cautious in the face of various risks, organisations often prefer to wait until the last minute to act, even when they know what to do.
The Frenglish name combines Ose (dare) + Go, representing the impulse to overcome reluctance, break out of procrastination and the beaten path, and take the lead before a crisis forces them to do so.
Oz’n’gO reminds us that in a world where everything is accelerating, resilience begins with a single movement: daring to decide, daring to prepare, daring to transform.
