What is a sponsorship deck someone who is interested in sponsoring an event I'm running asked for a deck what is it?

A sponsorship deck is usually required by a corporation interested in sponsoring some type of charity or nonprofit organization. The 'deck' is a detailed package that outlines what your event is all about. It usually includes a corporate sponsorship breakdown, outlining the different levels of contribution the company can make.

Make sure it is comprehensive and catchy, this is like your pitch on paper.
