At SISO Leadership Coference 2026, Shanna joins ASP CEO Jon Benjamin for an in-conversation session on AI visibility. Earlier this year, Shanna tested one of her own events in ChatGPT to see what came back. What she found prompted a significant piece of work across the CloserStill portfolio. She will share what that process involved, what it revealed and what it means commercially for event organisations that have not yet looked at their own AI discoverability.
