The Webflow.com website was mostly designed in Webflow, but we had some limitations at the time that required us to hand-code things. A new version is in the works that is completely created in Webflow, so it's only a matter of time :)
Pretty much all of our other sites (e.g. [1][2]) are already built/hosted/managed on Webflow.
Your web site is actually pretty terrible. Why do you need those fancy effects? The result is that text starts to fade out if I'm scrolling while I'm reading it, and images don't appear until I've scrolled past where the top of the image would be, so I have to scroll back up to see the top of the image that just appeared. Please, designers, stop trying to be clever for the sake of it. You're guaranteed to make the browsing experience worse for some people.
This is what we did with contentactivator.com. We wanted to promote our app through the sites we built. We even used it for our support site at help.contentactivator.com.
