ICE is one of the largest gaming industry trade shows, run by Clarion Events.
Erleah ran two personalised email campaigns during ICE Barcelona. Each one pointed an attendee at exhibitors, people and sessions matched to what they actually cared about.
Industry average email open rates for events sit around 20–25%. Erleah delivered 56-58%, more than double, because every email was personalised to what each attendee actually cared about.

support conversations handled by Erleah.
Rose City Comic Con (RCCC) is a Clarion Events property. Mini Erleah ran as a standalone, on-site support assistant, answering real attendee questions about the agenda, sessions, event info, logistics and venue services.
This was support only, proof the tool works on its own rather than only as part of a bigger package. 86% of attendees used it on their phones, on the show floor, while the event was happening.

Erleah won the Gold Prize at the Event Tech Live Launchpad Competition in November 2024. That turned into a 4-year partnership as ETL's Official AI Partner.
Erleah connected into five separate event platforms, ran the hosted buyers programme, and matched buyers to exhibitors directly. It was not added on afterwards. It ran the parts of the event that make money.
ETL is proof this is not just an attendee engagement tool. Done properly, it makes an event money directly: €100K+ in new revenue from a single event.
