Decks & documents are useful for forcing you to distil your thinking, but they won’t get you a deal.
Only face-to-face meetings get the deal.
Only relationships get the deal.
Spending your life fine-tuning decks and docs is a form of mental masturbation and delaying the real thing:
If you win over the customer, the rest is just “ticking the boxes”. If you don’t win over the customer, the rest is just finding excuses to not give you a deal.
Of course, you need your summary deck & document. And it needs to be professional. And it needs a call to action.
But success will come from your ability to win over the customer (or investor).
Don’t prepare your decks & documents.
Prepare your customer.
