As a former PhantomJS user, I certainly would have used you guys. I went through a lot of shit trying to set it up (this is phantomjs v1.3 i am talking about - mainly xvfb - which kept sending shitty screenshots). I am pretty sure you have a good market out there.

My suggestions: 1. Change your name - since you are doing a hosted phantomjs browser as a service, try to have either the word phantom or browser in your name. 2. Change your design - Go with bootstrap-based template for SaaS apps. 3. Too much content on your page. Cut them down. 4. Spin off couple of specialized tasks as separate services - screenshot capture and web scraping. 5. Quite a bunch of phantomjs and casper.js user groups/mailing lists. Actively participate in them.

Good luck!
