Thanks for the feedback! We're working on getting some authzed customer stories written - until then, we're able to share some of the logos featured on the website (Turo, HackerRank, Clear Street, etc) and stories from other oss projects using SpiceDB to handle permissions.
That said, if anyone here is interested in sharing their SpiceDB story, my DMs are open! There's also an open issue for anyone who would like to share.
