In a simple terms, a startup pitch deck, is a presentation that helps potential investors to learn more about your business.

In my opinion, the primary objective of a pitch desk is not to secure funding but to make a possibility to go to the next meeting. 

This is because, securing funding is a multi-step process. And, a good informative pitch deck is the first step of the ladder.

Pitch deck is a presentation which will make the future investors interested and engaged to your startup activities.
