As an angel investor, I can tell you that investors are generally looking for the same handful of items in your pitch deck. Make sure and deliver on the basics!
Go-to Market Strategy
Anything beyond these key points, can be asked during the Q&A. You do NOT want to spend your valuable Q&A time answering the basics, this is a huge lost opportunity.
Your goal is to cover enough about your business that it gains initial interest and prompts good follow-on questions. This information helps investors connect-the-dots on why you are the RIGHT team to bring this NECESSARY solution to a LARGE market, potentially delivering their required RETURN on investment.
Make sure your deck is not too word-heavy (you are delivering a lot of information for investors to digest in a small amount of time), you are energetic and clear, and that you keep to your allotted time.
