It is easily worth more than $49 to use this software. But $49 is the kind of price where a professional may just buy it from themselves without bothering to hassle their boss to buy it through the company.
This means less of a hard sell and more copies will be sold to people like you or me who discover it through HN or a tweet or something.
I do think they should increase the company price though, because once a company has decided they want to buy it, the sale is done. The difference between $79 and $199 isn't such a big deal, and something like $999 for 10 licenses could be done too.
