Site Review

Plenty to do with the site, especially content-wise:

There's no SEO at all: poor titles, no meta description, poor on-page treatment, not enough content... also no og: tags.

The homepage doesn't describe the proposition well in short snappy conversation-like style. Answer the what is sportscurve question with much shorter and snappier copy, same for the who it is for. You can expand the descriptions later on their own pages once the attention has been grabbed and the attention span lengthens.
Sportscurve is a training and performance tracking tool for players, coaches and managers.

The sportcurve_banner.png takes up too much space.

Any walkthroughs/demos and customer feedback.

There are no proper contact details. Important for trust and integrating with Google Places for Business and Google+.

You are duplicating a lot of content in modals on most pages which is a bad idea. Just give most of them their own pages for a number of reasons and put more content in some of the product pages like screenshots/walkthroughs etc. Also make pages for the 3 roles and explain how it works for them.

Use more Social Media, Twitter isn't enough.

Who are you, what are your credentials, why should I spend money on your product, why should I register - try to answer these questions.
