Last night, over and over, I saw VCs reviewing founders' decks and saying "I still don't understand what you do." That is... bad? Messed up? Astonishing? Horrific?
As a CEO, you're first job is to communicate the vision. And of all the documents you share, the deck is the one you have almost certainly spent the most time on.
So when an investor looks at that document and says "I don't get it" -- they are NEVER going to invest in you. You are obviously not capable of doing your job.
If you're raising capital, put your deck in front of people in your network. Especially friends that don't work in the same market as you.
Ask them these questions:
1) What do we do?
2) Who are our customers?
3) What's the problem we solve?
4) Why does that matter to them?
5) Why are we uniquely capable of solving this problem?
Straight up, if a friend of yours can't answer those questions precisely and accurately after looking at your deck, why in the world would you think an investor would be able to?
