I focus on two of the 4 advocacy types for this Maura, the validators who give feedback tend to do reviews, references, and work with your product team. If they are doing reviews or working with product now, I’d reach out to ask. Status seekers (people who want to take their career to the next level) tend to want to network, you’ll find them on social media, doing webinars in your space, participating in communities, and sharing content they’ve created.
If you look at your customer data or the lifecycle, I would look to ask after big wins, renewals, professional services wrap ups, and then post in the customer newsletter or even use an in-app ask.
