Optimize press nor lead pages supports this , btw.

According to the page code, Leadpages is what it was built on.

I talked to lead pages and they said it wasn’t. Was this custom coded and used lead pages theme?

It may not have used leadpages theme. In fact, the images are leadpages images but look to have been copied from leadpages and stored on the server…which is a big “no no”. So the outer part is a custom coded job (likely a page builder but not WP) but the inner (white) part is an infusionsoft for that has been inserted into the custom form.
