Unfortunately, it took me 14 page views and 1738 seconds to find the product tour on the page. In general, I found the organization of the different product descriptions to be confusing.
I also missed an answer to the 'How?' question. Of course, it depends on your preferred target audience but if it's smaller start-ups, it wouldn't hurt to get a bit more technical.
There's just one real negative point I could make: The site lacks credibility, in my opinion. There's neither a clear "FREE" message nor is there a "Plans and Pricing" page. I also missed a note about the status of the service. The word "solutions" has a negative connotation for me. There is no privacy policy, terms of use or 'About Us' page. Also, there's nothing with a more personal touch, no link to a blog, for example. The link to the Twitter account is hardly noticeable. Since 'Get started now' leads to a contact page, it just makes it look less trustworthy. You want me to contact you, but you don't say who you are.
If I had found the site by some other means, I would have been very warily.
Hope this helps.
