The duration of a brand activation depends on its scale and complexity. As a general rule:
Small-scale (pop-up, sampling): 4 to 6 weeks
Medium-sized (experiential event, 50–200 guests): 2 to 3 months
Large-scale (brand experience, 200+ guests): 3 to 6 months
Always start with the strategy: what do you want to achieve, and for whom? This is followed by concept development, site selection, production, and implementation. A tight schedule keeps the process manageable.
Hire an event planning agency early on. The more time there is for concept development, the more creative and impactful the result will be.
