Overall I like it. It immediately made me think of whichever 37signals product that does the exact same thing.
Initially I thought the page was just the left paragraph and the 3 image slider. I was about to leave until I noticed it scrolled down -- If I didnt find this on HN I would have closed it anyway).
So I'd like to see you add more pictures on the right slider or replace it with a video. If you keep the slider, increase the speed! You're using 1 picture with a few bullet points, it doesn't take 30 seconds to digest that.
