What alternative methods or platforms are being explored by your team for effectively communicating projects and updates to executive teams, aside from traditional slide decks?

We've used Miro (with frames and navigation) to extremely good success, and also we installed Jira wallboards on all the TVs of the executive floor, also helps with clear progress tracking

I'm encouraging my teams to be better strategic storytellers and focus less on the platforms. With that we've been investing additional time in the methods in which we communicate our work.

Loom videos, walking through products or slides

Jira boards clubbed with Confluence pages are strong communication tools for executive updates.
