Hi James and Jonathan, congrats on the launch!
In terms of the onboarding experience a quick feedback -- users should be allowed to type in a name of their company (it has to be edited later after the site is generated).
In terms of usefulness, I'd say I was quite impressed with the initial results. One of the major "writer's block" (or perhaps, "developer's block"?) I've faced with building marketing websites is figuring out what sections to add and how they should look. This gives a really good starting point and ideas to just help structure information - at least for someone like myself.
I did play around with the site a bit longer and realized that most / all of the generated sites are the same template with changes to the text and imagery (with perhaps some panels swapped out for others). I am not sure if that's completely true, but I hope, as you continue to develop the product, realize what the major use cases are, you can start to fine tune and better customize for the TAs needs.
