Think there are two ways to go with managing your startup burn.
1. Optimize for keeping the lights on as LONG as possible. Even if that means not hiring key people who can help you fast-track your success.
2. Hire key (effective) people and make things go as FAST as possible. Even if that shortens the runway.
The problem is that in both cases you spend all the money. but with option 1 you're ALSO spending opportunity cost. I.e. Someone else will come along and disrupt you before you have a chance to get properly situated in the market.
