Startups in 'founder mode' have an edge

Am I missing something with the latest buzz around the 'founder mode'? It's a new concept for startups that transitioned into an enterprise. Not seed/series A stage startups. In those cases you don't have any other option at all?

I believe going against the notion that CEOs should delegate work as the company grows is great but I don't get why seed stage startup founders act like they are enlightened from this and brag about being in 'founder mode' is something special. You simply don't have any other option?

So how is 'founder mode' - which lost all of its meaning at this point is an edge for 'startups'?
