I'd second the website makeover. It doesn't have to be super sexy, but right now it looks like it's from the late 90's, early 2000's(at least on desktop).
On Desktop:
That black bar at top is bulkier than it needs to be. You can try moving 'the merrier way' from under 'Growthzilla' to the right of it instead. This would allow you to slip it down a bit. There's also no branding. You don't need to hire a marketing company or anything to do this, just try to get a common theme going because right now your colors are all over the place. The slider is moving a little too fast. If you extended the time by about 15-20% I think that's be great for slower readers like myself. The initial call to action under the slider is good. Like snowmaker said, definitely explain more about your product and what sets it apart. Again with the colors, your icons next to your features are purple/blue and some other text is too, but then you have orange buttons and your logo is orange and yellow. I would probably just stick to orange/yellow since they're in your logo and you can couple this with various shades of gray. The purple/blue completely clashes with the orange/yellow. For the testimonials, your slider isn't centered.
On Mobile:
Everything looks much better on mobile than on the desktop. I see nothing you really need to change here, other than the branding/theme/colors. If you're using Bootstrap, it's really easy to use your current logo for mobile and a more horizontal logo on desktop using by using the hide/visible classes(.visible-md-block, hidden-md).
