If your organisation or event is seeking corporate partners, you have a responsibility to be able to communicate the value and benefits of being associated with you to potential sponsors. Gail. S. Bower of Sponsor Park, points out the fact that you are the one who knows your event or organisation inside out – it is you that needs to educate and empower partners from the first time you sign them up through the years of your partnership and collaboration, is to assist them in achieving success in their sponsorship of your event or organisation.
