When I first visited the homepage I felt overwhelmed with options. All those links up the top could probably go to the footer. The main CTA should be that "Get Started" button. Currently you've also got a sign up button which is a bit confusing. (I know that you've got a little note explaining that they don't have to sign up, but most people aren't going to read that.)

You really just want to show images of what it can do and get them to upload an email and grab their email address, then you can ask them to sign up after they've got their photo and you can also ask via email.
