Get a good biz dev person
As a CEO, when you start a company, you are the only one that need to sell until you consolidate Product Market Fit. A biz dev will be only 50% efficient after months of training.
It's a tricky position as you want somebody with the right mix of tech knowledge, business knowledge and bullshiting ability.
Sadly, in my limited experience, there seems to be a large amount of people that excel at the latter but not so much at the other categories.
