Prospecting and networking approach
Arrive with focused project materials to make meetings productive. Prepare PDF plans, a list of required materials and a budget range. Prioritize exhibitors by topics relevant to your pipeline for renovation, energy upgrades or trade services and book meetings in advance. During stand conversations ask targeted technical questions and request references or case studies.
For exhibitors the practical advice is to frame every pitch around product or service, measurable improvement and financing options. Clear messages accelerate decision making by contractors and developers who visit the fair.
