Being in a start up is a game. We have an idea and we are playing the game to make that idea as successful as possible. We need tools in this game - engineers, lawyers, accountants etc.. are all tools. Some tools are more useful in the beginning than others. Some tools become more important as our startup matures.

Now MBA is this awesome general degree that teaches you a bit of everything - accounting, sales, some business law. This makes you a versatile tool! :D. The question is, do you know how to best serve a startup? What can you do? What do you want to do? How will you make up for your lack of experience in a certain area - can you learn quickly? Adapt?

Many startups these days start out with the core team being engineers - they're looking to build something, so it makes sense. That said, some startups may do well with a gritty MBA who can go out there and talk to tons of people to generate / prove ideas and report back to the engineering team; take care of accounting; HR stuff if need be; etc... basically it means being the CEO from day one without worrying about the title.

Is that what you're looking for or do you just want a cusy desk job as a junior manager? ;)
