Hospitality Net was the official Media Partner for EHL's Open Innovation Summit, where we had the opportunity to interview some of the event's most visionary voices. In this conversation, we spoke with Michael Levie, Founding Partner at CitizenM Hotels, about the urgent need to modernize tech architecture in hospitality, why middleware and microdata matter more than ever, and how CitizenM maintains its inclusive, rebel spirit - even under the Marriott umbrella.
