Seems a simple change for HubSpot to implement that results in a huge benefit for customers (as indicated by the number of comments and upvotes).
Indeed, HubSpot themselves actually implements this idea on their own home page (I assume through the custom embed code that other people have shared). If you go to their book a demo form and select company size = 1, you get one thank you page, whereas if you select company size = 10000+ and you get a different thank you page.
Can we please get this functionality implemented for users without the need to loop in developers?
