> Keep the team small. All doers, no talkers.

Totally agree here. Best teams I work in were the small and focused ones!

I can't really see why small companies with high revenue/traction are portrayed as "risky/volatile" because they have 5-15 employees.

To some extent, the same is with single-founders. Why "dismiss" a 1-man team if he did the work of 2-3 people?

PS: I know the motivations for both, but there is a distinction between possibility and likelihood of a risk to actually occur.
