OTOH (writing from 20-year working experience with two thirds of it in early stage startups) more often than not founders are not actually competent technically or otherwise. And “letting people do their job” at best means a permission to speak up and endlessly argue with conflicting opinions from colleagues, but not a permission to execute if that means commanding others to do something, because the delegation of power to do that is not being given due to the aforementioned lack of expertise and inability to judge if an idea is good or bad.
