> In their picture of the world, you, the founders, should only build a product and talk to customers, everything else is superfluous and waste of time. Hiring is waste of time, paid advertising is waste of time, content is waste of time, talking to investors is waste of time, getting media coverage is waste of time.

Getting you to focus on those two things, particularly the second one which many technical founders are initially out of their comfort zone doing (I need to work on it myself), is probably a huge value add in itself if they're successful at doing just that.
