The deck itself needs to tell a story. If it is a new market that you are addressing, think about how to articulate its size and importance in a defensible way. Have a clearly articulated actual pain point that your product is solving and show evidence. Be focused on having a clear view of who is going to pay you for your product. Do not assume that people know your market in depth. As the leader of the business, you need to be the face and cannot outsource this. If you are showcasing your team, make sure it really is a showcase, not just an intro at the start. A simple chart could be very misleading and kill your credibility.
