Was there A/B testing done on whether to provide it? I'm asking, because the simple sign-up popup requires me to agree to the Refund Policy, which definitely hints that me paying money is part of the equation at some point.
When I thought about using your service for my business, I was so disgusted with the disingenuity of not showing your prices on the homepage (I had to email support, who sounded annoyed -- and not at all apologetic -- to query the price points), I decided to not even give you guys a shot.
I know my company would be willing to pay up to $50 monthly for something like this, but without having to give you my email address I don't see why I would want to deal with you.
If your plan/plans are 50+ then I guess you did make a good choice after all :)
