Off the top of my head... While mint.com isn't entirely a finance app, it was sold for $170 million. I'd assume that price would not have been paid if it were only grossing $80k/year. Also Bloomberg has a free app that's pretty awesome. It's hard to peg how much revenue that app is responsible for bringing in, but regardless, I'm sure it adds more than $80k/year of value to the company or they'd can it.
