My mic drop moment...
One day I'm going to go into a 'Startup Sales 101' talk and do my typical 90 minute primer in 2 minutes:
Do you have customers? Call every one of them and ask them why they work with you. Going forward ask every single customer that signs up the same question.
Don't have customers? Call 50 potential customers and ask them what their biggest pain about [insert the problem you're solving] is.
Take all this information and put it into a one-page doc to send potential customers.
Use that doc to create a simple landing page.
Use this messaging to target your top 25 dream customers and get their attention using something other than a generic, cookie-cutter e-mail.
Be real. Be honest.
Use the next 88 minutes to do the above.
