Can't find the documentation. Your site gives me no idea of how you actually integrate it or how it works at all. Wouldn't sign up without that information.
I honestly have no idea what your product does. How is it different to Google Analytics, Optimizely, Mixpanel, et al?
Apart from explaining more about what you do exactly, I'd recommend including testimonials and results (if you have them) - "we helped X increase their ROI by Y" for example.
Edit: 'Totally free until August 2016'? I'd recommend phrasing this as 'sign up now and get our Business package FREE for the next 5 months'. 'Free until August 2016' doesn't sound very appealing as a potential customer.
