1) The website doesn't justify a 499 dollar app. (the website is to simple)
2) The GUI of the software is old fashion and to simple which isn't worth 499.
3) Your marketing can be much better. You don't appeal to your audience which are system administrators. I had to look for 3 minutes to understand what deployer did.
4) Where are the bullets with the benefits? Like saving time, money error etctetc
