If you're building a pricing page - you need to know who will pay for which feature, at what threshold they're willing to pay, and how much, right?

No.

If you don't know any of the answers, you can start with just one - say who will pay for what - and set out to speak to that group to better understand their needs. If you're not sure of the threshold - how many clicks should be free before they pay - you can simply remove those from the pricing page, and test different thresholds within the product itself. (100 clicks - time to upgrade!)

Is the pricing page there to give us some revenue or learn if people will pay? Do we even need a pricing page for that?
