Which event management platforms and tools have you found most effective for streamlining event logistics and tracking performance?

Despite working at a Fortune 500 company, we're relatively simple. We use a good amount of our own technology (IE: Marketing Cloud for invites at large scale events, Salesforce CRM, Slack, Tableau). For event logistics and project management towards an event, we primarily use Google spreadsheets and Quip. We've also explored Asana to support this as well. We also have our go to agencies and vendors for event production and work with them via Slack.

Given how big our event portfolio can be across the company, we have a Tableau dashboard that allows us to see which events are coming up. We also have a self-serve pre-event and post-event Tableau dashboards for our event leads to pull performance.
