Just sharing my own experience..I used to work for start-ups and now I am working for a seemingly boring, profitable company that is not venture funded. By boring I meant there is not alot of media news about them. They just bunker down and do the work. There's way less craziness - more focused, mature approach towards problems.
These companies do the regular stuff such as advertising via the usual channels- job boards and LinkedIn. And sometimes with recruiters - not those fancy ones who recruit for start-ups.
