About us

Planning events sucks. We’d know.

We built Diana, an AI event coordinator who answers every inquiry, checks real availability, and files the lead into your CRM. She takes the repetitive back office off a venue team’s desk so they can get back to the part that actually matters.

Where this goes

The operating system for how the world gathers.

That’s the long arc: the infrastructure layer of the global experience economy. It starts with one coordinator doing one job properly.

  1. 01

    Gatherings move the world forward

    Ideas are born, alliances form and culture takes shape when people come together. That’s worth protecting.

  2. 02

    The back office shouldn’t eat the event

    Teams lose weeks to sourcing, chasing and tracking instead of the experience itself.

  3. 03

    She should work like a teammate

    Not a chatbot bolted on. Someone who takes real work off a coordinator’s desk, under their control.
