Building a PM Portfolio: What to Include When You Can’t Share Work?

Hey, I’m applying to a bunch of roles, and I often come across a field on job applications that asks for a website or portfolio.

I never thought of creating a website for my work but it seems product companies view it as a useful way to learn more about candidates

What should a PM include in their portfolio or website? Beyond the usual product teardowns, what else adds value? Obviously, I can’t write about the products I’m currently working on since they fall under my org’s.

Experienced PMs here — what do you think about this? Any ideas for creating a meaningful portfolio while navigating these constraints?
