Setting a Pitch Deck
A pitch deck is fairly open ended for what you want to highlight about your business, however there are certain things that many investors like to see in a pitch deck. Sequoia Capital, one of the largest VCs in the valley, has an blog post that many entrepreneurs have used to begin thinking about how they want to approach their deck.
The pitch deck is yours, so it is okay if it does not follow the exact structure in the link above. Many investors, however, will want to see/learn about the above items either in further discussion or in diligence, especially the team in the early stages.
