There's an inflection point in growing startups where our focus shifts from building products and helping customers to hiring staff and dealing with internal bullshit. That shift in focus is the death knell for growing startups as it slowly and completely takes our eye off the ball.
If we look at larger companies we can see this in full view. 90% of their focus (sometimes all of it) is spent internally with warring parties and fiefdoms more focused on their jobs and career paths than anything the company actually produces. (I've made the argument before that all the important stuff was probably done long before them anyway.)
Our job as Founders is to do everything in our power to prevent this loss of focus, and it absolutely starts with us.
