I’ll add to his feedback, I don’t have a clue how your service works. Sure, your landing page tells me you’ll customize my landing pages. How? Not set up crap in your visual editor. How does it decide which version to send to whom? Comes across as snake oil to me.

We're constantly reworking our marketing site, but to make it more technical for the HN crowd (our audience is mostly marketers), it's an "if-this-then-that" engine for your website.

- If referred by foo.com OR came over with particular UTM params OR landed on /foo THEN change out testimonials to be able foo (using similar underlying tech that Optimizely, et al use)

or

- If visitor, who has opted in previously, has the "Customer" tag in the ESP/CRM that our customer has linked their site to, then ditch the signup form on the homepage and put a training video (or something)

It's basically a rules engine that looks at on-site behavior (pages viewed, referring domain, query string params, cookie data, etc) and allows you to combine that with ESP/CRM backend data (tags, custom fields, subscriber vs anonymous), and make content changes (replace text, hide an element, swap out an image, etc) as a result of a visitor belonging to a particular segment you've defined.
