There are 2 schools of thought that most people assume are contradictory.
First that, people buy from other people – so folks buy because they like the other person and if they like the person they will buy anything (or everything from that person).
The other school of thought is that people want to buy from a trusted brand, so even if the individual goes away the business remains to support what they bought.
Actually they are both true.
People dont just buy from other people, they buy from people they like.
Which brings me to the demo day pitch. If you dont create an emotional connect with your audience quickly enough (first 30 seconds) you are likely to be perceived as wooden, robotic or impersonal.
