I really like the concept of what you are doing. I was actually thinking "we need that". Your website turned me off a bit. Like the last comment, the shot of the kid was a bit weird. I had a hard time understanding what your site does. The UI is not terrible but I think you could be doing a better job. Especially since Mobile UIs are so critical to success.
Anyway, keep it up cause I like the concept and would actually use it.
Thanks for your comment. I guess we have to invest some more time into our website. But concerning your point about the UI that needs improvement: Do you mean the website UI or the builder UI seen in one of our videos? And did you check the site on a mobile device or on a desktop? (cause or mobile site is not really existent yet...)
We will definitely keep up and if you subscribed for beta we will inform you about important updates.
Actually, it's not the worse site, but the site could use a little polishing. There's actually a lot of material put out in HN in the past about that. A lot of landing pages look like this example: http://visualwebsiteoptimizer.com/split-testing-blog/landing...
