We're online sports games of skill that allow you to play for money: play short-term fantasy contests, win cash tonight. Suffice it to say that this is a super hot space, so if you like sports and making money, this could be the place for you.
We're built on RoR, founded by highly successful internet marketers (as in, tens of millions of users and hundreds of millions of dollars), and we have a ridiculously nice office in downtown SF with a sky high view of the Bay and all three bridges.
Reach out to russ [at] doubleup after checking out our site, and let me know where you'd like to fit in.
