Our Clients


Since our inception in 2004 we’ve made corporate social responsibility and community engagement a priority, encouraging all of our team members to get involved. We also work with our clients where possible, for example in our GainingWheels programme, to identify individuals/organisations who are in need of assistance but unable to afford this.

Our Scholar Programme reaches out to the young and deserving future leaders of our industry, offering them work experience and a chance to network with trade colleagues. Our Scholars are students who wish to pursue careers in the business events industry and who demonstrate outstanding potential for future industry leadership.

In addition, we offer Industry Support – our consulting services, either pro-bono or at a reduced fee – for developing/emerging destinations which meet our criteria. We have been privileged to have worked with IMEX during their Wild Card programme, and our industry support continues through various projects.

Last but certainly not least, Community Engagement is very important to us. These can be the local communities where our projects take us, or global NGO organisations working to make the world a better place.
