O3 Hostess Agency supplies briefed, multilingual event staff for corporate events, trade shows, VIP hospitality, product launches, brand activations and jobfairs. O3 Group is a marketing and events partner based in Heverlee (Leuven) that coordinates guest reception and event staffing across Belgium. We select people around your brief, sector, language requirements and dress code, rather than availability alone. Your contact proposes hostesses, promotional teams, cloakroom attendants, shuttle drivers or parking hosts suited to your project. French, Dutch and English are central to our team, with other languages available on request. Each crew is briefed on the guest journey and led by an on-site staffing supervisor who coordinates with your project manager. Because we also build stands, print signage and produce events, reception teams can work within a production we manage from start to finish. You keep one point of contact for preparation and execution. Hostess Agency is one of our 8 services under 360° Brand Services. Active since 2010, O3 Group brings 15+ years of experience and handles 350+ projects per year.
