It looks cool but the pricing is huge. We're raising a round now and this looks like something that would be helpful but at $89 a month? Probably not, certainly not without a short trial.
I have literally all the problems you outlined in the blog and so I checked out the app. It looks cool but why on earth do I have to signup for an account after browsing for a bit? I understand that at some point you want people to login for the enquiry but it makes browsing a new application very very irritating.
Additionally, my biggest annoyance with the commercial real estate is the "MANY OFFICES UP TO Xsqft/FROM £Y". I was hoping this would be something where the lettor had to list offices as opposed to just a general space that can be broken up.
