Why are you trying to force yourself as a comparison to other companies? In certain cases it makes complete sense and from a brand building perspective can work wonders, but it doesn't always work. I would focus more on describing the value of the product in a clear and concise way.
I agree, I've never been a fan of "X for Y" type of analogies, but our service/services is hard to describe succinctly -- we want to get across that we are a "smart" job search company, and we have the thumbs up and thumbs down like Pandora, but also that we are more than that, including giving analytics that end up being very useful.
We've thrown around "Data driven startup job search" and "Recommendation based job search engine", but those are pretty vague and don't feel quite right either.
To be honest, we're so close to this, that we would love an outsiders take on us -- if you had to describe us, what would you call us? Maybe we just always overthink it and someone will have the perfect way to describe us :)
