The Dark Matter of a Startup

Over the course of a day or a month or a year, a key person might do all sorts of tasks, with their variance in role inversely proportional to the age of the startup. But what they do in the short term is clearly identifiable. No dark matter to be found.
Having an all-rounder is good for short term goals. Ultimately having clear responsibilities and goals is better as the scope should be narrowed down to achievable goals, whether its a startup that's bootstrapping, or gone really successful
But in early days there are 2-3 people and none of them can be dark matter otherwise this person evolves into a vortex or blackhole for your capital/profits.
I think a employee like this can partially hurt an early-age startup (as also sid says).
You either sell or develop in a startup, if you're doing neither or these, you're useless. Pick one and do it.
