The last way that your content can continue to provide value to your customers after a sale, is to simply start the process over again.

This means going back to the guided discovery phase and discovering something new, or finding solutions to new challenges they are facing.

What I like about this idea is that it involves focusing on the meta-value of the content you create for the guided discovery phase. If you want past customers to be able to discover something new, you need to be one step ahead of them, and creating content is one way to explore new opportunities to provide value and demonstrate it to customers.

Put another way, past and present customers should get the sense through your latest content that you and your offerings are regularly evolving and leveling up. They should feel (rightly) that any new purchase will be more valuable than any past purchase, and ultimately they should be excited to participate.
