A Job Ad that is Ideal for a Budding Startup

Why is this ad "ideal for a budding startup"? I'm sure mixpanel is a nice place to work, but there doesn't seem to be anything unique about this ad, so I'm not sure why it's being held up as a model to emulate.

I like this ad a lot. It's not overblown and avoids obnoxious cliches (ninja, pirate, whatever). It's succinct, to the point and honest.
