Branching logic on landing pages

I've got a landing page with a form on it.  I'd like to display a different message on the resulting thank you page based on their answers to the form.  For example, if they self-identified as an SMB company, I'd display one message, whereas if they identified as an Enterprise client, I'd display another.  Is this possible?  I don't see anyway to branch between two different landing pages, so I'm wondering if anyone has a different approach.

Thanks in advance,

Damian
